(c)  the implementation of any of the measures referred to in the Agreement.
s 23: Am 2000 No 92, Sch 8.17 [3].
24   Principles to be applied
(1)  This section applies if an action, claim or other proceeding is brought against the relevant water authority for compensation for damage caused by:
(a)  the construction, maintenance, operation or control of works, or
(b)  the carrying out of operations referred to in the Agreement, or
(c)  the implementation of any of the measures referred to in the Agreement.
(2)  The court is to have regard to the following principles in determining whether any, and if so what, compensation for damage is to be made:
(a)  no compensation is to be made for any diminution or deterioration of the supply of water to which any person may be entitled, unless the diminution or deterioration is such as to deprive the claimant of a supply of water previously legally enjoyed by the claimant and unless the diminution or deterioration is the direct, and will be the permanent, result of the completed works,
(b)  no compensation is to be made for the taking or diverting of any water which the relevant water authority is empowered by or under this Act or the Agreement to take or divert, either permanently or temporarily, from any river, creek, stream, watercourse, lake, lagoon, swamp or marsh,
(c)  there is to be considered in reduction of all claims for compensation for injury:
  whether, by reason of the execution of any works under this Act, any, and if so what, enhancement in value of any property of the claimant, wherever situated, has been directly or indirectly caused, and
  whether any, and if so what, immediate or proximate benefit has been gained by or become available to the claimant by reason of the construction or use of any such works,
and a deduction is to be made accordingly from the amount which, but for this paragraph, would have been paid or payable as compensation,
(d)  the measure of damages is in all cases to be the direct pecuniary injury to the claimant by the loss of something of substantial benefit accrued or accruing and is not to include remote, indirect or speculative damages,
(e)  if the injury complained of appears to be of a permanent or continuing character, or likely to be repeated, a sum may be awarded which the court may declare to be a compensation for all injury, loss or damage sustained in respect of the matter complained of to the date of judgment in the proceedings and also for all future injury, loss or damage in respect of the same matter, and thereafter no further compensation may be made in respect of any such future injury, loss or damage.
25   Stay of proceedings until completion of works
(1)  This section applies if compensation is sought to be recovered from the relevant water authority for any injury alleged to be the result of:
(a)  the construction, maintenance, operation or control of works, or
(b)  the carrying out of any of the operations referred to in the Agreement, or
(c)  the implementation of any of the measures referred to in the Agreement,
that are incomplete at the time of the alleged injury and of the claim for compensation in respect of the alleged injury.
(2)  The court may, on an application by the relevant water authority, make an order directing the stay of proceedings on the claim for compensation until the completion of those works or operations or implementations of those measures or for such period, stated in the order, as the court considers sufficient for their completion or implementation. The proceedings to recover compensation are stayed accordingly.
(3)  When the stay of proceedings expires, the claimant may resume the proceedings for the recovery of compensation without commencing any fresh proceedings.
26   Compensation for injury to other interests
(1)  This section applies if compensation is sought to be recovered in respect of any injury to property that may affect interests in reversion as well as in possession in the property and that is alleged to be the result of:
(a)  the construction, maintenance, operation, or control of works, or
(b)  the carrying out of any of the operations referred to in the Agreement, or
(c)  the implementation of any of the measures referred to in the Agreement.
(2)  The claimant for compensation is required, before any sum is awarded as compensation, to satisfy the court:
(a)  as to the nature and extent of the respective estates or interests in the property of the claimant and all other persons (if any) whose interests are said to be affected, and
(b)  that the claimant has given sufficient notice to all such other persons of the proceedings brought by the claimant to obtain compensation under this Act.
(3)  A person, apart from the claimant, having an interest in property as referred to in subsection (1) and who, whether on being notified by the claimant or not, appears before the court is entitled to be heard in respect of the person’s interest in the compensation to be awarded.
(4)  In awarding any sum by way of compensation, the court is to award and apportion, as between the claimant and all other persons appearing to have an interest in the property concerned, in such manner as to the court seems fit, the amounts to be received by any or some or all of them respectively out of that sum, as compensation for the injury caused or likely to result to the respective interests of the claimant and those other persons in the property.
(5)  A person, other than the claimant, to whom an amount is awarded or apportioned under subsection (4) has all such remedies and means of recovering that amount from the relevant water authority as though the person had originally been a plaintiff in the action in which the award or apportionment was made.
Part 5 General
27   Supreme Court
(1)  The Supreme Court may exercise jurisdiction in relation to the Commission and the Commissioners in the same manner and to the same extent as it could if the Commission were a body representing the Crown in right of the State and as if the Commissioners were State officers.
(2)  If a court of the Commonwealth or another State that is a party to the Agreement exercises a power under a law corresponding to subsection (1), the Commission and Commissioners must comply with an order or decision of that court.

(a)  a minute or record, or copy, referred to in subsection (1), or
(b)  a document referred to in subsection (2),
is taken, unless the contrary is proved, to be such a minute or record, copy or document, as the case may be.

(2) 
The Commission must determine the flows referred to in sub-clause 87 (1) in such manner as it sees fit.
88.    
Variation of South Australia’s entitlements
The Commission may from time to time, at the request of a Commissioner for South Australia, vary for a specified sequence of months any of the monthly quantities which that State is entitled to receive under clause 86 without increasing the total of those quantities for that sequence.
89.    
Use of Lake Victoria
If the Commission decides that the flow or prospective flow of the River Murray downstream of its junction with the Great Darling Anabranch is, or will be for any month in excess of the sum of—
(a)   the quantities which South Australia is entitled to receive in that month under clause 86 or 88;
(b)   any quantities which, in the opinion of the Commission, ought to be and can be impounded in Lake Victoria during that month with the object of filling that storage at some time before the end of the next ensuing month of May; and
(c)   any quantities required for use by New South Wales and Victoria, downstream of the junction of the River Murray and the Great Darling Anabranch,
South Australia may receive that excess in addition to the quantity of water which it is entitled to receive under clause 86 or 88.

DIVISION 3    
WATER ACCOUNTING
102.    
General
The following provisions give effect to the principles set out in the preceding Divisions of this Part.
103.    
Allocation of water to New South Wales and Victoria
(1) 
In respect of any period—
(a)   the natural flow of the River Murray at Doctors Point; and
(b)   the volume of water calculated in accordance with clause 10 of Schedule G,
must be allocated between New South Wales and Victoria as provided in sub-clause 103(2).

Half the water entering the Menindee Lakes Storage from the Darling River is allocated to New South Wales and half to Victoria.
(2) 
Of the water allocated to Victoria and stored in the Menindee Lakes Storage, Victoria must cede 4,170 megalitres each month to New South Wales.
105.    
Tributary inflows
(1) 
The quantity of water which in any period enters the upper River Murray downstream of Doctors Point from a tributary, or from any artificial outfall approved by the Commission for the purposes of this clause, other than quantities referred to in clause 104, is allocated to the State from which the water enters the upper River Murray.

(a)   diverted from the upper River Murray by an offtake under the jurisdiction of that State, unless the Commission determines otherwise; and
(b)   calculated under sub-clause 12(1) of Schedule G, in the case of New South Wales; and
(c)   calculated under sub-clause 12(2) of Schedule G, in the case of Victoria.
107. 
  (Repealed)
108.    
Losses
(1) 
Any water which is lost by evaporation or other means from the upper River Murray is deemed to have been used by New South Wales or Victoria.
(2) 
Unless otherwise determined by the Commission—
(a)   losses attributable to evaporation from a major storage will be deemed to have been used in proportion to the quantities of water allocated to New South Wales or Victoria in that storage;
(b)   losses attributable to an unregulated flow in any part of the upper River Murray will be deemed to have been used in proportion to the flow allocated to New South Wales or Victoria in that part of the river;
(c)   all other losses will be deemed to have been used half each by New South Wales and Victoria.
(3) 
For the purposes of this clause an “unregulated flow” means a flow which has not been planned by the Commission.
109.    
New South Wales’ and Victoria’s supply to South Australia
For the purposes of this Division any water supplied in any month to South Australia which it is entitled to receive under clause 86 or 88 is deemed to be supplied half each by New South Wales and Victoria and the Commission must make appropriate adjustments to allocations between New South Wales and Victoria of water in the upper River Murray so as to give effect to those States’ obligations under clause 93.
110.    
Commencement of continuous accounting of carryover of stored water
Half the water in each major storage on 1 December 1989 is deemed to have been allocated to New South Wales and half to Victoria.
111.    
Reallocation of water between New South Wales and Victoria
(1) 
By agreement between a Commissioner for New South Wales and a Commissioner for Victoria, any quantity of water allocated to one of those States and in store in any of the upper River Murray storages or in transit in a specified part of the upper River Murray, may be exchanged for a quantity of water allocated to the other State and in store in another of the upper River Murray storages or in transit in another specified part of the upper River Murray, if such an exchange of water does not prejudice the entitlement of South Australia.
(2) 
The Commission may at any time, with the consent of either New South Wales or Victoria, determine that certain quantities of water in transit in the upper River Murray are surplus to the requirements of that State and reallocate the whole or part of such quantities from that State to the other State.
112. 
  (Repealed)
113.    
Efficient regulation of the Murray River
Any water used by either New South Wales or Victoria or supplied to South Australia by either of those States is deemed to be provided from water allocated to that State and the Commission may, as necessary to ensure the availability of appropriately allocated water at the place of such use or supply, reallocate quantities of water in the upper River Murray but must not thereby alter the total quantities of water allocated to New South Wales or Victoria respectively, in the upper River Murray.
114.    
Accounting procedures
Subject to clauses 110, 111, 112, 113, 115 and 120, the quantity of water in any part of the upper River Murray and which is allocated to either New South Wales or Victoria is deemed—
(a)   to increase in any period by the quantity of water allocated to that State flowing into that part in that period, and
(b)   to decrease in any period by any quantities of water—
(i)   used by that State by way of diversion or loss from that part in that period, or
(ii)   passed from that part in that period for—
—   downstream use by that State,
—   supply by that State to South Australia,
—   conveyance to another part of the upper River Murray as water allocated to that State, or
(iii)   released from that part in that period and determined under clause 121 to be a release of water allocated to that State, or
(iv)   spilled from that part in that period and deemed under clause 116 to be a spill of water allocated to that State.
115.    
Internal Spills
(1) 
In any major storage, water allocated either to New South Wales or Victoria must be re-allocated to the other State to prevent the quantity of water allocated to either State in the storage exceeding half the lesser of—
(a)   the target capacity of the storage, or
(b)   the quantity of water stored when releases are being made for flood mitigation.
(2) 
In Hume and Lake Victoria, “target capacity” means the capacity of the reservoir at the Full Supply Level.
(3) 
In Dartmouth “target capacity” means the lesser of—
(a)   the capacity of the reservoir at the Full Supply Level, or
(b)   the quantity of water stored when water is being released through the hydro-electric power station and the storage level is above the level specified by the Commission for the operation of the power station.
(4) 
In Menindee Lakes “target capacity” means the greater of the capacity—
(a)   at the Full Supply Level, or
(b)   at such higher level as may be determined from time to time by the Commission.
(5) 
When water in Dartmouth Reservoir is to be re-allocated under sub-clause 115 (1) and there is capacity in Hume Reservoir available to the State from which water is to be re-allocated to store some or all of the re-allocated water, a compensating adjustment must be made in Hume Reservoir so that the accounts of the State from which the water is to be re-allocated in Dartmouth Reservoir are not thereby reduced.
116.    
Accounting for spill from storages
Any quantity of water spilled from any of the upper River Murray storages, including water released solely to provide space for the retention of floodwaters, is deemed to be water spilled out of the waters allocated to New South Wales or Victoria respectively, in such proportions as minimizes the re-allocation of water under sub-clause 115 (1).
117.    
Accounting for releases from Dartmouth Reservoir
(1) 
Whenever the storage level in Dartmouth Reservoir is above the level determined for the purposes of this sub-clause by the Commission, releases made from Dartmouth Reservoir through the hydro-electric power station will be deemed to be spills and will be accounted for as provided in clause 116.
(2) 
No release from Dartmouth Reservoir will be attributable to the allocation of water to New South Wales or Victoria if the quantity of water in Dartmouth Reservoir allocated to that State is less than or equal to half the minimum operating storage in the reservoir.
(3) 
Releases from Dartmouth Reservoir other than those covered by sub-clauses 117 (1) and 117 (2) will be attributable to the allocation of water to New South Wales or Victoria in such proportions as tend most to equalize the quantities of water allocated to those States in Hume Reservoir.
118.    
Accounting for releases from Hume Reservoir
(1) 
Any release made from Hume Reservoir for the deliberate purpose of transferring water to Lake Victoria for use at a later date will be attributable to the allocation of water to New South Wales or Victoria in such proportions as tend most to equalize the quantities of water allocated to the respective States in Lake Victoria and the Menindee Lakes Storage.
(2) 
Releases from Hume Reservoir other than those covered by sub-clause 118 (1) will be attributable to the allocation of water to New South Wales or Victoria in such proportions as satisfy the expected downstream water requirements of each State.
119.    
Accounting for releases from Menindee Lakes Storage
(1) 
For the purposes of this clause releases from Menindee Lakes Storage consist of—
(a)   water required to maintain a flow throughout the main course of the Darling River downstream of Menindee Lakes;
(b)   water released to satisfy use by New South Wales in the main course of the Darling River downstream of Menindee Lakes;
(c)   water released through the Lake Cawndilla Outlet Regulator;
(d)   water released down the main course of the Darling River downstream of Menindee Lakes Storage to satisfy directions given by the Commission under sub-clause 95 (4);
(e)   any other water released from the Menindee Lakes Storage which can be used either to supply South Australia’s entitlement under clause 86 or 88 or to supply water to Lake Victoria.
(2) 
Whenever New South Wales is using water pursuant to sub-clause 92 (1) all release from Menindee Lakes Storage will be attributed to the allocation of water to New South Wales.
(3) 
Whenever sub-clause 92 (1) does not apply to the use of water by New South Wales from the Menindee Lakes Storage—
(a)   releases under paragraph 119 (1) (a) will be attributed equally to the allocations of water to New South Wales and Victoria;
(b)   releases under paragraph 119 (1) (b) and 119 (1) (c) will be attributed to the allocation of water to New South Wales;
(c)   releases under paragraph 119 (1) (d) and 119 (1) (e) will be attributed to the respective allocations of New South Wales and Victoria in such proportions as tend most to equalize the water in Lake Victoria allocated to each State, provided that such proportions do not—
(i)   cause the water allocated either to New South Wales or to Victoria to fall below 240,000 megalitres;
(ii)   cause water to be re-allocated between the States under clause 115.
120.    
Reallocation of water in Menindee Lakes Storage
(1) 
At the conclusion of any period during which New South Wales is using water pursuant to sub-clause 92 (1), the quantities of water stored in the Menindee Lakes Storage and allocated respectively to New South Wales and Victoria must be adjusted so that the difference between those quantities is the same as the difference in the allocated quantities at the beginning of that period.
121.    
Accounting for dilution flows
(1) 
Whenever the Commission directs under clause 95 that the flow of water is to exceed the water order at a particular point, unless the Commission determines otherwise, the proportion of the water order attributed respectively to New South Wales and Victoria must be increased by such amounts as tend most to equalise the respective allocations to New South Wales and Victoria of the total flow at that point.
(2) 
For the purpose of this clause the “water order” is the flow of water at a particular point which is necessary—
(a)   to meet diversions by New South Wales and Victoria, losses and dilution flows downstream of that point;
(b)   to meet South Australia’s entitlement; and
(c)   to supply storages downstream of that point.

•   any tributary within that State other than the River Darling, and
•   any artificial outfall from that State approved by the Commission for the purposes of clause 105;
and
(ii)   any water allocated to that State which flows to South Australia in excess of South Australia’s entitlement under clause 86 or 88.
If (ii) exceeds (i), the account kept under this paragraph must be set at zero;
(c)   all water allocated to that State which is supplied by it to meet South Australia’s entitlement under paragraph 86 (a).
125.

SCHEDULE E    
INTERSTATE TRANSFER OF WATER ALLOCATIONS
PART 1    
PRELIMINARY
1.    
Objects of Schedule
The objects of this Schedule are as follows—
(a)   to facilitate and promote the interstate transfer of water allocations co-ordinated by the Commission;
(b)   to provide for the Scheme to be implemented on a trial basis in that it will initially only apply to specific water diverters and high security water allocations and to a restricted part of the Mallee region;
(c)   to improve the efficiency and effectiveness of consumptive water use in ways which facilitate environmental sustainability but which do not increase or accelerate environmental degradation;
(d)   to establish a procedural framework and set of standards so that the Scheme is accountable and does not result in increased levels of salinity, reductions in environmental flows or degradation of the natural environment;
(e)   to provide for the suspension of the operation of this Schedule if there is an increase in, or acceleration of, environmental degradation from the use or management of water that has been diverted interstate in accordance with the Scheme;
(f)   to give effect to water trading arrangements in accordance with the terms of the Ministerial Council’s decision regarding the long-term level for off-stream diversions in the Murray–Darling Basin;
(g)   to enable the Commission to adjust the quantity of water to be delivered to the States as a result of the Scheme.
2.    
Definitions
(1) 
In this Schedule—
“exchange rates” means the exchange rates determined by the Commission in accordance with clause 7 of this Schedule;
“Scheme” means the scheme for the interstate transfer of water allocations established under this Schedule;
“State of destination”, in relation to a water allocation, means the State to which the water allocation is transferred;
“State of origin”, in relation to a water allocation, means the State from which the water allocation is transferred;
“transfer register” means the register required to be kept by the Commission under clause 17 of this Schedule;
“water allocation” means a privately held statutory entitlement to divert water on a river system in the Murray–Darling Basin.
(2) 
A reference in this Schedule to a “water cap” is a reference to the total volume of water permitted to be diverted within the Murray–Darling Basin in line with the Ministerial Council’s decision to limit diversions to 1993-94 levels of development.
3.    
Application of Schedule
(1) 
This Schedule applies to water allocations—
(a)   that are supplied from the River Murray between Nyah and the barrages; or
(b)   that are River Murray licences supplied from the Lock 10 weir pool.
(2) 
This Schedule applies to the following types of water allocations—
(a)   private statutory entitlements to divert water for use by the holder of the statutory entitlement concerned;
(b)   high security water allocations, being water allocations described—
(i)   in New South Wales as private high security licences; or
(ii)   in South Australia as water licences granted under the Water Resources Act 1997; or
(iii)   in Victoria as private diversion licences.
(3) 
This Schedule applies to and in respect of that part of a water allocation that is proposed to be transferred permanently, that is, a transaction where the rights of the seller in relation to the part of the water allocation to be transferred are cancelled when the transaction is concluded. The part of a water allocation that is proposed to be transferred may include the whole of the water allocation if the seller is proposing to transfer the whole of the water allocation.
(4) 
This Schedule does not apply to temporary transfers of water allocations.
(5) 
Any water allocation that comprises a statutory entitlement to a bulk supply of water for the purpose of on-supply through reticulated systems to users other than the holder of the statutory entitlement (for example, to irrigation districts) may not be transferred under this Schedule.
4.    
Suspension of Schedule
(1) 
A State Contracting Government may from time to time, after consultation with the Ministerial Council, suspend or limit the operation of this Schedule in that State on the grounds that the State Contracting Government considers that—
(a)   there has been an increase or acceleration of environmental degradation resulting from the use or management of water diverted pursuant to the transferred water allocations; or
(b)   inadequate progress has been made by any one of the States involved in the Scheme in achieving full cost recovery water pricing.
(2) 
The Ministerial Council may, from time to time, resolve to suspend or limit the operation of this Schedule—
(a)   if a Contracting Government fails to provide a report to the Commission in accordance with clause 18 of this Schedule; or
(b)   for such reasons, or on such other grounds, as the Ministerial Council thinks fit.
(3) 
Any resolution under sub-clause (2) operates to suspend or limit the operation of this Schedule according to the terms of the resolution.
PART II    
GENERAL OPERATIONAL PROVISIONS
5.    
Adjustment of delivery of State entitlements under Part X of the Agreement
(1) 
The delivery of water pursuant to each State’s entitlement under Part X of the Agreement, and the water accounting provisions under that Part, may be adjusted by the Commission in order to take into account, and to give effect to, the Scheme.
(2) 
Water deliveries to South Australia are to be increased by a volume equal to the adjusted net balance of water allocation transfers into that State as recorded in the transfer register at the end of each financial year.
(3) 
The supply of water by New South Wales and Victoria to South Australia under clause 93 of the Agreement is to be increased in each case by a volume equal to the adjusted net balance of water allocation transfers into South Australia from the State concerned as recorded in the transfer register at the end of each financial year.
(4) 
The delivery of water in Hume Reservoir to New South Wales is to be increased by the adjusted net balance of water allocation transfers from Victoria to New South Wales as recorded in the transfer register at the end of each financial year, and the delivery of water in Hume Reservoir to Victoria is to be decreased by that same amount. In accordance with sub-clause (8), a transfer from New South Wales to Victoria would equal a negative net balance of water allocation transfers from New South Wales to Victoria.
(5) 
During any special period of accounting declared by the Commission (referred to as “a period of special accounting”), the Special Accounts of State diversions under paragraph 124 (a) of the Agreement are to be decreased by a volume equal to the adjusted net balance of water allocation transfers into the State concerned as recorded in the transfer register.
(6) 
The Special Account of water supplied to meet the entitlement of South Australia under paragraph 124 (c) of the Agreement is to be decreased by a volume equal to the adjusted net balance of water allocation transfers into South Australia from the State concerned as recorded in the transfer register.
(7) 
Adjustments under sub-clauses (2)–(6) are to be made in equal amounts in the months of September to April inclusive. If South Australia’s entitlement is restricted at any time in accordance with clause 127 of the Agreement, those restrictions (that is, the same percentage reductions) are to apply in relation to the adjustments.
(8) 
For the purposes of this clause, the “adjusted net balance” is the net balance of water allocation transfers following adjustment by the application of the appropriate exchange rates. Any such adjusted net balance may be a positive amount or a negative amount.
6.    
Adjustment of water cap
(1) 
The water cap in respect of each Contracting Government is to be adjusted by the Commission—
(a)   to maintain the integrity of the overall water cap for the Murray–Darling Basin; and
(b)   to reflect the water allocations that have been transferred interstate under the Scheme.
(2) 
The water cap in respect of the State of origin is to be lowered, and the water cap in respect of the State of destination is to be correspondingly raised, to ensure that the total level of off-stream diversions remains within the total of the respective water caps of the States.
(3) 
For the purposes of adjusting the water cap in respect of a particular State, a water allocation that is transferred interstate under the Scheme—
(a)   is taken to have been fully used (or by such lesser proportion as may be determined by the Commission) in the State of origin; and
(b)   is taken to have been transferred for full use (or by such lesser proportion as may be determined by the Commission) in the State of destination.
7.    
Exchange rates
(1) 
The Commission is to determine exchange rates for the purposes of the Scheme.
(2) 
The exchange rates are set out in the document called “Exchange Rates for the Inter-State Transfer of Water Entitlements in the Mallee Region” issued by the Commission.
(3) 
The object of exchange rates is to limit the impact that any particular transfer made in accordance with the Scheme might have on other water users.
(4) 
The exchange rates are to take into account—
(a)   losses through transmission in the river channel; and
(b)   losses through changes in the level of security for the supply of water,
resulting from the operation of the Scheme.
(5) 
The Commission may vary the exchange rates from time to time.
(6) 
Water allocations that are transferred interstate under the Scheme—
(a)   are subject to any adjustment by the Commission at the time of the transfer so as to give effect to any losses identified under the exchange rates; and
(b)   are not to be increased so as to give effect to any gains identified under the exchange rates.
(7) 
Any such gains are to be set aside by the Commission for environmental purposes. The Commission is to establish an account in respect of these gains.
(8) 
A State of origin may also determine exchange rates for the purposes of adjusting the volume of water in respect of a statutory entitlement in order to reflect the amount of water that has been used under the entitlement.
8.    
Charges
(1) 
The Council may, after considering any recommendation by the Commission, adjust the share of contributions due by each State under Part VII of the Agreement (referred to as “Part VII charges”) in proportion with any variation in the delivery of water under State entitlements that has resulted from the operation of the Scheme.
(2) 
Adjustments to Part VII charges are—
(a)   to be determined annually in accordance with the water pricing principles approved by the Commission from time to time; and
(b)   to take into account any variation in the delivery or allocation of water under State entitlements from the beginning of the Scheme.
(3) 
Once the Commission has made an adjustment of any Part VII charges in accordance with this clause, any charges imposed by the State of origin which had been applicable to a water allocation transferred interstate cease to be recoverable by that State.
(4) 
Subject to the laws of the State of destination, that State may recover from the recipient of the transferred water allocation the additional Part VII charges resulting from the transfer, together with such other charges as may be recoverable from the holders of other similar private statutory entitlements to take water in the State of destination.
9.    
Salinity and drainage strategy
(1) 
The operation of the Scheme is subject to the requirements of Schedule C to the Agreement.
(2) 
Any salinity debits or credits arising from the dilution effects brought about by water allocation transfers to or from South Australia are to be assigned at the end of each financial year under Schedule C to the upstream State involved in the transfer concerned.
(3) 
Any salinity debits or credits arising from the dilution effects brought about by water allocation transfers between New South Wales and Victoria are to be shared equally by those two States.
(4) 
Any salinity debits or credits arising from changes to salt accessions brought about by the operation of the Scheme are—
(a)   to be assigned in New South Wales and Victoria to the State in which the change occurs; and
(b)   to be treated as a requirement in South Australia for zero impact on salinity.
10.    
Environmental and supply considerations
(1) 
The licensing authority of each Contracting Government must, in assessing or determining any proposed transfer of a water allocation under this Schedule, ensure that—
(a)   the licensing authority takes into consideration the Ministerial Council’s policies on environmental flow management; and
(b)   the proposed transfer is not inconsistent with those policies.
(2) 
The licensing authority of each Contracting Government must ensure that—
(a)   any water allocation that has been transferred to the State under the Scheme; and
(b)   the use of water diverted pursuant to such a transfer,
are subject to the same regulatory provisions and environmental considerations that apply in respect of water allocations granted by the licensing authority in the State and in respect of the use of water diverted pursuant to an intra-State transfer.
(3) 
The environmental considerations referred to in sub-clause (2) are set out in the document called “Environmental Clearances for New Irrigation Developments in the Mallee Region” (as approved by the Ministerial Council from time to time), and may include such matters as land use development, movement of water between high and low impact zones, channel capacity, clearance of native vegetation, on-farm irrigation standards, consideration of ground water accessions and surface drainage.

Environmental Objectives And Strategy For River Murray Increased Flows
(1) 
Before the commencement of the second complete Water Year after the Corporatisation Date, the Ministerial Council must determine:
(a)   a strategy for retaining and releasing River Murray Increased Flows to be implemented by the Commission; and
(b)   the environmental objectives for the River Murray Increased Flows,
in accordance with the provisions of this clause.
(2) 
The Strategy:
(a)   must include a provision to the effect that River Murray Increased Flows have first priority from River Murray Above Target Releases;
(b)   may provide that water credited to the River Murray Increased Flows in Commission Storages Account need not be released during the Water Year in which it is credited;
(c)   unless the Ministerial Council otherwise determines, must not have a significant adverse impact upon the security of entitlements to water;
(d)   must integrate the environmental objectives for the River Murray Increased Flows with other environmental initiatives on the River Murray;
(e)   must include adaptive management principles to allow the ability to optimise environmental benefits; and
(f)   must prescribe appropriate environmental reporting and monitoring conditions.
(3) 
The Ministerial Council must determine the environmental objectives and Strategy in accordance with the following principles:
(a)   Natural diversity of habitats and biota within the river channel, riparian zone and the floodplain should be maintained or enhanced.
(b)   Natural linkages between the river and the floodplain should be maintained or enhanced.
(c)   Natural metabolic functioning of aquatic ecosystems should be maintained or enhanced.
(d)   Elements of the natural flow regime, in particular, seasonality should be retained or enhanced as far as possible, in the interests of conserving a niche for native rather than invasive exotic species and in maintaining the natural functions of the river.
(e)   Consistent and constant flow and water level regimes should be avoided where practical, as this is contrary to the naturally variable flow regime of the River Murray.
(f)   The general principles of ecosystem services should be recognised.
(g)   Environmental benefit should be optimised.
(4)
