Part 1 Introduction
1   Name of Plan
This Plan is the Water Sharing Plan for the Lower Gwydir Groundwater Source 2019 (hereafter this Plan).
2   Nature and status of this Plan
(1)  This Plan is made under section 50 of the Water Management Act 2000 as amended (hereafter the Act).
(2)  This Plan covers the core provisions of section 20 of the Act for water sharing, and additional provisions of section 21 of the Act, and other relevant matters.
3   Date of commencement
This Plan takes effect on 1 July 2019.
4   Area to which this Plan applies
The area in respect of which this Plan is made is that area of land within the Gwydir and Border Rivers Water Management Areas known as the Lower Gwydir Groundwater Source (this groundwater source) as shown on the Plan Map (WSP047_Version 2) Water Sharing Plan for the Lower Gwydir Groundwater Source 2019 held by the Department (the Plan Map).
Notes—
1   
The Gwydir and Border Rivers Water Management Areas are shown on the map in Appendix 1.
2   
The Plan Map is part of this Plan and can be viewed on the NSW legislation website.
5   Waters to which this plan applies
The water in this groundwater source includes all water contained in the unconsolidated alluvial sediment aquifers associated with the Gwydir River, its tributaries, and effluents downstream of Gravesend.
Note—
Water supply works drilled through the unconsolidated sediments into the underlying Great Artesian Basin (GAB) are tapping a different resource. On plan, they may lie within the boundaries of the Lower Gwydir Groundwater Sources, however they are within the deeper GAB Groundwater Source and are not included as a part of this Plan.

(h)  extent to which local water utility requirements have been met,
(i)  extent to which native title rights requirements have been met, and
(j)  extent of recognition of spiritual, social and customary values of groundwater to Aboriginal people.
Part 3 Basis for water sharing
12   Basis for water sharing
This Part is made in order to give effect to section 5 (3) of the Act, and in accordance with sections 20 (2) (c) and 21 (e) of the Act.
13   Climatic variability
(1)  This Plan recognises climatic variability and therefore that the level of natural recharge to this groundwater source will vary.
(2)  To give effect to subclause (1), this Plan has provisions that manage—
(a)  the sharing of water in this groundwater source within the limits of water availability on a long-term average basis, and
(b)  water extractions to enable the protection of groundwater dependent ecosystems, aquifer integrity and water quality in this groundwater source.
14   Recharge
(1)  The overall basis for water sharing in this Plan is the average annual recharge to this groundwater source, estimated to be 38,000 megalitres per year (hereafter ML/yr) plus the requirements for basic landholder rights at the commencement of this plan.
(2)  The Minister may under section 45 (1) (b) of the Act amend subclause (1) to vary the average annual recharge value following further recharge studies undertaken by the Minister.
Note—
The extent to which this change may impact on access licence holders is limited by clause 29.
Part 4 Environmental water provisions
15   Environmental water provisions
This Part is made in accordance with sections 5 (3) and 8 (1), 8 (2) and 20 (1) (a) of the Act.
16   Planned environmental water
Note—
It is anticipated that the planned environmental water provisions in this Part and management of local impact provisions in Part 10 of this Plan will also protect the cultural and spiritual values of groundwater (see clause 9 (h)).
(1)  This Plan establishes the following planned environmental water rules—
(a)  subject to Part 10 Division 2 of this Plan, the physical water contained in the storage component of this groundwater source will be reserved for the environment,
(b)  subject to Part 10 Division 2 of this Plan, 15% of an amount that is equal to the long-term average annual recharge to this groundwater source minus basic landholder rights requirements at the commencement of this plan, being 5,700 ML/yr, is reserved for the environment.
(2)  The Minister may under section 45 (1) (b) of the Act amend subclause (1) (b) vary the proportion of recharge reserved as planned environmental water based on further studies of groundwater ecosystem dependency undertaken by the Minister.
Note—
The studies may recommend management options other than reservation of a portion of recharge to protect groundwater dependant ecosystems.
Note—
The extent to which this change may impact on access licence holders is limited by clause 29.
17   Adaptive environmental water
(1)  Water may be committed in this water source for environment purposes by an adaptive environmental water condition pursuant to section 8B of the Act.
(2)  The holder of an access licence may request that the Minister impose an adaptive environmental water condition in respect of the whole or a part of the share component of the access licence.
(3)  The condition imposed under subclause (2) will continue until the holder requests its removal.
(4)  An access licence may be held by the Minister, Local Land Services or another public body to the extent that the whole or part of that access licence has been surrendered as a result of on farm water savings made by works or other improvements, subject to—
(a)  the share component of the access licence held being equal to the value of the on-farm water savings made,
(b)  the access licence held being the highest priority category in this water source, other than a specific purpose category, and
(c)  an adaptive environmental water condition being imposed on the access licence and that condition not being removed.
(5)  The adaptive environmental water condition specified in subclause (1) and the plan for implementation of that condition, as required by section 8E (7) of the Act—
(a)  are to be established by the Minister, and
(b)  shall be such as to ensure that there will be a contribution to the objectives of this Plan.
(6)  The allocation of water for access licences with an adaptive environmental water condition will be in accordance with the available water determination for the relevant category of access licence under this plan.
(7)  If the adaptive environmental water condition on an access licence requires the water to be left in the water source for environmental purposes, then the water allocation account is to be debited when the water is available in accordance with the adaptive environmental water condition on the access licence.
(8)  If the adaptive environmental water condition requires the environmental water to be taken from the water source then the water allocation account is to be debited when it is taken.
(9)  For the purposes of auditing compliance with the long-term extraction limit under this plan, the delivery of water pursuant to an access licence that has been committed as adaptive environmental water shall be accounted for as extraction where it occurs pursuant to a licence under subclause (2) or subclause (4).
(10)  To the extent that the water allocation of an access licence which is subject to an adaptive environmental water condition is not required to meet the requirement of the condition it may be the subject of an assignment dealing in accordance with the Dealings Rules in this plan.
(11)  Notwithstanding subclause (10) an access licence with an adaptive environmental water condition may be the subject of any other dealing permitted by the Dealing Rules in this plan, provided the benefit to the environment provided for in the adaptive environmental condition is not diminished.
(12)  At the commencement of this clause, there were no access licences with an adaptive environmental water condition in this groundwater source.
Part 5 Basic landholder rights
18   Basic landholder rights
(1)  This Part is made in accordance with sections 5 (3) and 20 (1) (b) of the Act.
(2)  If a landholder is unable to exercise their basic landholder rights due to interference of their supply by extraction authorised by access licences—
(a)  the Minister may amend a water supply works approval to allow the landholder’s affected bore to be replaced or deepened to ensure continuing access to water for basic landholder rights’, or
(b)  the Minister may amend another water supply works approval so that basic rights water may be supplied by an alternative water supply work means during critical times.
(3)  In accordance with the legislative requirements, the Minister may impose a charge on access licence holders in this groundwater source under section 114 of the Act, as a contribution to the costs of activities or works associated with subclause (2).
(4)  Basic landholders rights exercised under section 52 of the Act must be exercised in accordance with any guidelines established by the Minister with respect to the reasonable use of water for domestic consumption and stock watering by landholders authorised to use water for either or both of those purposes.
Note—
The Minister may, by order made under section 323 of the Act, impose temporary restrictions on basic landholder rights when it is necessary to do so in the public interest, such as to cope with a water shortage or threat to public health or safety.
Note—
The Minister may enforce any reasonable use guidelines by serving orders on individual landholders under section 325 of the Act. The Minister may also order individual landholders accessing basic landholder rights to take specified measures to protect the environment, to preserve basic landholder rights or to overcome a threat to public health under section 328 of the Act.
19   Domestic and stock rights
Note—
It is not recommended that the water from this groundwater source be consumed without prior treatment. Land use activities may have polluted the groundwater in some areas.
(1)  At the commencement of this Plan the water requirements of holders of domestic and stock rights are estimated to be a total of 700 ML/yr.
Note—
The volumes of water identified in subclause (1) are the total volumes of water estimated for domestic and stock rights in this groundwater source.
(2)  This Plan recognises that the exercise of domestic and stock rights may increase during the term of this Plan.
Note—
Increase in use of domestic and stock rights may occur as a result of an increase in the number of landholdings overlying this groundwater source, or as a result of the increase in the exercise of domestic and stock rights by existing landholders.
20   Native title rights
The requirement for water to satisfy native title rights is the water that may be taken in the exercise of native title rights in accordance with the Native Title Act 1993 of the Commonwealth, including any determination of native title.
Notes—
1   
This Plan may be amended if there is a native title determination in accordance with the Native Title Act 1993 of the Commonwealth by which water is required.
2   
Native title rights may be exercised in accordance with the Native Title Act 1993 of the Commonwealth, including section 211 of that Act.
Part 6 Bulk access regime
21   Bulk access regime
(1)  This Part is made in accordance with section 20 (1) (e) of the Act.
(2)  This Plan establishes a bulk access regime for the extraction of water under access licences in this groundwater source having regard to—
(a)  the environmental water provisions established under Part 4 of this Plan,
(b)  the requirements for basic landholder rights identified under Part 5 of this Plan, and
(c)  the requirements for water for extraction under access licences identified under Part 7 of this Plan.
(3)  The bulk access regime established in subclause (2)—
(a)  recognises the effect of climatic variability on the availability of water as provided for under Part 3 of this Plan,
(b)  establishes rules according to which access licences are granted as provided for in Part 8 of this Plan,
(c)  recognises and is consistent with limits to the availability of water as provided for in Part 9, Division 1 of this Plan,
(d)  establishes rules according to which available water determinations are to be made as provided for in Part 9 Division 2 of this Plan,
(e)  establishes rules according to which access licences are managed as provided for in Parts 9 and 10 of this Plan, and
(f)  establishes rules with respect to the priorities according to which access licences are to be adjusted as a consequence of any reduction in the availability of water as provided for in Part 9 of this Plan.
Part 7 Requirements for water for extraction under access licences
22   Requirements for water under access licences
This part is made in accordance with section 20 (1) (c) of the Act.
Note—
The amount of water specified in this Part represents the total volumes or total shares specified in the share components on access licence in this groundwater source. The actual volume of water available at any time will depend on climate, access licence priority and the rules in this Plan.
23   Share components of domestic and stock access licences
It is estimated that at the time of commencement of this Plan, the share components of domestic and stock access licences authorised to extract water from this groundwater source will total 200 ML/yr.
24   Share components of local water utility access licences
It is estimated that at the time of commencement of this Plan, the share components of local water utility access licences authorised to extract water from this groundwater source will total 3,572 ML/yr.
25   Share components of aquifer access licences
It is estimated that at the time of commencement of this Plan, the share components of aquifer access licences authorised to extract water from this groundwater source will total 28,920 ML/yr.
26   Changes to share components
This Plan recognises that the total requirements for water for extraction within this groundwater source may change during the term of this Plan as a result of—
(a)  the granting, surrender or cancellation of access licences, or
(b)  the variation of local water utility access licences under section 66 of the Act.
Part 8 Rules for granting access licences
27   Rules for granting access licences
(1)  This Part is made in accordance with sections 20 (2) (b), 61 and 63 of the Act, having regard to the limits to water availability in this groundwater source and the need to protect groundwater dependent ecosystems, aquifer integrity and groundwater quality.
(2)  Applications for access licences may be made and access licences granted in this groundwater source if they are—
(a)  a specific purpose access licence for which an application may be made under the Water Management (General) Regulation 2018 (hereafter the Regulation) in accordance with section 61 (1) (a) of the Act, or
Notes—
1   
Clause 10 of the Regulation provides for the following specific purpose access licences to be applied for—
(a)  a local water utility access licence (subcategory “domestic and commercial”), for the purpose of domestic consumption and commercial activities,
(b)  a domestic and stock access licence (subcategory “domestic”), for the purpose of domestic consumption,
(c)  an aquifer access licence (subcategory “town water supply”), for the purpose of supply to communities for domestic consumption and commercial activities,
(d)  any category of specific purpose access licence (subcategory “Aboriginal cultural”), for Aboriginal cultural purposes.
2   
Pursuant to sections 66 (3) and 66 (4) of the Act, the Minister may also vary the share component of a local water utility access licence at 5 year intervals, or on application of the local water utility where there is rapid growth in population.
(b)  an access licence with a zero share component in accordance with sections 61 (1) (b) and 63 (5) of the Act, or
(c)  an access licence that may be granted in accordance with a dealing that is permitted under Part 11 of this Plan, or
(d)  a domestic and stock access licence, if the water taken under the licence is to be delivered via the Lower Gingham Pipeline.
(3)  In applying for a new access licence, the applicant must establish the purpose and circumstances relating to that access licence, and that the share and extraction component sought will be the minimum required to meet that purpose and circumstance.
(4)  Access licences granted under this Part cannot be used to extract water through a water supply work (bore) located in areas where the extraction authorised by the access licence plus the full extraction authorised by existing access licences nominating water supply works (bores) located in the area and the exercise of basic landholder rights, are likely to cause an adverse local impact, as outlined in Part 10 Division 2 of this Plan.
(5)  An application may not be made for a domestic and stock access licence if the granting of the licence would cause the total share components of domestic and stock access licences granted under subclause (2) (d) to exceed 200 ML/yr.
Part 9 Limit to the availability of water
Division 1 Long-term average extraction limit
28   Extraction limit
(1)  This Division is made in accordance with section 20 (2) (a) of the Act.
(2)  The extraction limit for this groundwater source is initially 32,300 ML/yr, plus the total requirements for basic landholder rights at the commencement of this plan.
29   Variation of extraction limits
(1)  The Minister may under section 45 (1) (b) of the Act amend clause 28 to vary the extraction limit in accordance with—
(a)  any change to the average annual recharge arising from subclause 14 (2), and
(b)  any change to the planned environmental water arising from subclause 16 (2).
(2)  If there is any change to the extraction limit arising from subclause (1) then—
(a)  the extraction limit will not be greater than 38,760 ML/yr, plus the total requirements for basic landholder rights at the commencement of this plan and,
(b)  the extraction limit will not be less than 25,840 ML/yr, plus the total requirements for basic landholder rights at the commencement of this plan.
30   Compliance with the extraction limit
(1)  Water extraction in this groundwater source will be monitored each water year to determine if there is any growth in volume extracted above the extraction limit specified in clause 28, based on a comparison of the extraction limit against the extraction within this groundwater source over that year and the preceding 2 years.
(2)  For the purposes of auditing compliance with the extraction limit, if water that—
(a)  pursuant to an access licence is committed as adaptive environmental water to be left in the aquifer for environmental purposes, then extraction will be assumed to be equal to 100% of the available water determination made under clause 31, or
(b)  pursuant to an access licence is committed as adaptive environmental water to be extracted for environmental purposes, then extraction will be that measured through the approved water supply work (bore).
(3)  If the 3 year average of extraction in this groundwater source exceeds the extraction limit established in clause 28 by 5% or greater, then the available water determination made for aquifer access licences under clause 31 (5) for the following water year, should be reduced by an amount that is assessed necessary by the Minister to return subsequent total water extraction to the extraction limit.
Division 2 Available water determinations
31   Available water determinations
(1)  This Division is made in accordance with section 20 (2) (b) of the Act.
(2)  All available water determinations in this groundwater source shall be expressed as either—
(a)  a percentage of the share component for all access licences where share components are specified as megalitres per year, or
(b)  megalitres per unit of share component for all access licences where share components are specified as a number of shares.
(3)  An available water determination for each category of access licence in this groundwater source should be made at the commencement of each water year.
(4)  The available water determinations made at the commencement of the water year for domestic and stock and local water utility access licences should be 100% of share components.
(5)  The available water determination made at the commencement of the water year for aquifer access licences should be such that the total of available water determinations under this clause equals the extraction limit set in clause 28 (2) as varied by clause 29 minus the total requirements for basic landholder rights, minus the total available water determinations for domestic and stock and local water utility access licences, or such lower amount as results from the operation of clause 30 (3).
Part 10 Rules for managing access licences
Division 1 General
32   Rules for managing access licences
This Part is made in accordance with sections 20 (2) (b) and 21 (a) and 21 (c) of the Act, having regard to—
(a)  the environmental water rules established in Part 4 of this Plan,

33   Water allocation account management
This Division is made in accordance with sections 20 (2) (b) and 21 (c) of the Act.
34   Water allocation accounts
In accordance with section 85 of the Act, a water allocation account shall be established for each access licence in this groundwater source.
Note—
Water allocation may be assigned to, or from, these accounts by a water allocation assignment made under section 71T of the Act, where these are allowed under rules specified in Part 11 of this Plan.
35   Accrual of water allocations
Water allocations will be accrued into water allocation accounts each water accounting year in accordance with the Minister’s available water determinations as specified in clause 31.
36   Annual accounting for water extraction
(1)  Water taken from this groundwater source will be accounted for at least annually.
(2)  Water taken by a water supply work (bore) nominated by an access licence will be periodically debited against the access licence water allocation account.
(3)  A water allocation account shall remain at or above zero at all times.
(4)  Unused water allocations in the water allocation accounts of domestic and stock access licences or of local water utility access licences, cannot be carried over from one water year to the next.
(5)  In any water year, subject to local impact management restrictions arising from Part 10, Division 2 of this Plan, water taken from this groundwater source under a local water utility access licence or a domestic and stock access licence may not exceed a volume equal to—
(a)  100% of the share component of the access licence,
(b)  plus any water allocations assigned from another access licence under section 71T of the Act in that year,
(c)  plus any water allocations re-credited in accordance with section 76 of the Act in that year, and
(d)  minus any water allocations assigned to another licence under section 71T of the Act in that year.
(6)  Unused water allocations in the water allocation accounts of aquifer access licences may be carried over from one water year to the next, subject to subclause (7).
(7)  The maximum amount of unused water allocations that can be carried over under subclause (6) is equal to 2 ML per unit of share component.
(8)  In any water year, subject to local impact management restrictions arising from Part 10, Division 2 of this Plan, water taken from this groundwater source under an aquifer access licence may not exceed a volume that is equal to—
(a)  2 ML per unit of aquifer access licence share component,
(b)  plus any water allocations assigned from another access licence under section 71T of the Act in that year, and
(c)  minus any water allocations assigned to another access licence under section 71T of the Act in that year.
(9)  Subclauses (4) to (8) do not apply to any access licence specified in Schedule 2 of this Plan.
(10)  Any access licence specified in Schedule 2 will be subject to the water allocation account management rules specified in that Schedule, in addition to clauses 33, 34, 35, and 36 (1) to (3).
Division 3 Management of local impacts
37   Management of local impacts
This Division is made in accordance with section 21 (a) of the Act.
38   Extraction interference between neighbouring bores
(1)  The minimum allowable distance between a property boundary and extraction from new and replacement water supply works (bores) authorised to extract equal to or greater than 20 ML/yr is 200 metres.
(2)  New and replacement water supply works (bores) authorised to extract less than 20 ML/yr which are within 100 metres of any basic rights water supply work, will require an investigation of potential impacts on neighbouring water supply works (bores).
(3)  The Minister may, upon request of the applicant for the water supply work approval, vary the distance restrictions specified in subclause (1) if the Minister is satisfied that—
(a)  a hydrogeological study undertaken by the applicant, and assessed as adequate by the Minister, demonstrates that the location of the new or replacement water supply work will have no more than minimal potential for adverse impact on existing authorised extraction, and
(b)  all potentially affected access licence and water supply work approval holders and adjacent landholders have been notified by the proponent, and
Note—
Potentially affected access licence holders are typically neighbouring access licence holders and/or those in the near vicinity.
(c)  there is a process for remediation in the event that any adverse impact occurs in the future, specified as conditions on the water supply work approval.
(4)  Subclause (1) does not apply to extraction under existing access licences until such time as the nominated water supply work (bore) is replaced.
(5)  The distance restrictions specified in subclauses (1) and (2) do not apply to the grant or amendment of a water supply work approval if the Minister is satisfied that the water supply work is solely for basic landholder rights.
Note—
The intention of this clause is to minimise the impact of extraction under new access licences on extraction under existing access licences. It is intended to develop models to support hydrogeological assessment of the adverse impacts of new groundwater extractions on existing licensed extraction.
39   Water level management
(1)  The Minister may declare that, in order to maintain water levels within this groundwater source, local access rules are to apply in a defined area known as a local impact area.
(2)  If water levels in any part of a groundwater source have declined to such an extent that, in the opinion of the Minister, an adverse impact is occurring, or is likely to occur, extraction from all water supply works (bores) within a local impact area declared under subclause (1) that are nominated by an access licence will be restricted to such an extent and for such time as is required to reinstate water levels to such a degree as to mitigate or avoid that impact.
Note—
This clause recognises that in some locations, at certain periods of high groundwater demand, critical water level declines may occur, and that additional extraction limitations may be required. The Department will identify monitoring bores, specify the target levels, and determine the method for specifying an affected area.
40   Water quality management
(1)  The beneficial uses of this groundwater source are raw water for drinking, and irrigation, based on beneficial use classes identified in the Australian and New Zealand Environment and Conservation Council Water Quality Guidelines 2001, and the National Health and Medical Research Council Raw Water for Drinking Purposes Guidelines 1996.
Note—
It is not recommended that the water from this groundwater source be consumed without prior treatment. Land use activities may have polluted the groundwater in some areas.
(2)  Water quality decline will be deemed unacceptable if extraction is likely to cause water quality to decline to a lower beneficial use class.
(3)  The Minister may declare that, in order to protect water quality within this groundwater source, local access rules are to apply in a defined area known as a local impact area.
(4)  If unacceptable water quality declines are resulting from extraction, extraction from all water supply works (bores) within a local impact area declared under subclause (3) that are nominated by an access licence will be restricted to such an extent and for such time as required to halt that decline, or restore the beneficial use of this groundwater source.
(5)  Extraction under local water utility access licences shall be subject to restrictions under this Part, but not to such an extent as access is denied.
41   Protection of groundwater dependent ecosystems
(1)  Extraction of groundwater from a new or replacement water supply work (bore) is excluded within 100 metres of high priority groundwater dependent ecosystems, or any creek or river, for those exercising basic landholder rights, and 200 metres for extraction authorised by all other access licences unless the water supply work (bore)—
(a)  only draws water from an aquifer at depths greater than 50 metres, and
(b)  has an impermeable seal, constructed within the annulus of the water supply work (bore), as specified by the Minister, to isolate aquifers above 50 metres depth, and to prevent water ingress from the shallow aquifers.
Note—
Subclause (1) will not apply to extraction from an existing water supply work (bore) until such time as the work is replaced.
(2)  High priority groundwater dependent ecosystems are those listed in Schedule 3.
(3)  Pursuant to section 42 (2) of the Act, the Minister may identify further high priority groundwater dependent ecosystems and include them in Schedule 3 at any time, based on further studies of groundwater ecosystems dependency undertaken by the Minister.
(4)  The Minister should consult with the Minister for the Environment before adding further high priority groundwater dependent ecosystems to Schedule 3.
Note—
At the commencement of this Plan, there is not sufficient information to identify high priority groundwater dependent ecosystems within the Lower Gwydir Groundwater Source.
42   Protection of aquifer integrity
(1)  The Minister may declare that, in order to protect the integrity of the aquifers within this groundwater source, local access restrictions are to apply in a defined area known as a local impact area.
(2)  The Minister may, on presentation of evidence of land subsidence or aquifer compaction, restrict extraction from all water supply works (bores) nominated by an access licence within a local impact area declared under subclause (1), to such an extent and for such time as to stabilise that subsidence or compaction.
Note—
This clause recognises that damage of aquifers through excessive water storage loss is irreversible, and destroys the resource for future water users, including the environment.
43   Extraction Restrictions
The Minister may, in the event of local impacts restrictions arising from this Division, impose, by Order, a reduction in annual, quarterly, weekly or daily extraction rates from water supply works (bores) in the local impact area.
Note—
The Minister will attempt to give licence holders prior notice of any local impact restrictions so as to minimise the impacts of such restrictions on access within a season.
44   Group registration
This Plan allows for the formation of a group of access licences with respect to the sharing of local impact restrictions arising from this Division, subject to the following rules—
(a)  the group register will be maintained by the Minister,

Part 11 Access licence dealing rules
46   Access licence dealing rules
(1)  This Part is made in accordance with section 20 (1) (d) of the Act and with the Minister’s access licence dealing principles gazetted under section 71Z of the Act.
(2)  Applications for access licence dealings may be granted subject to the Minister’s access licence dealing principles gazetted from time to time under section 71Z of the Act and the rules in this Part.
Note—
There are a number of mechanisms within the Act, called access licence dealings, to change either the ownership of all or part of an access licence, or the location within a water source at which all or part of the share and extraction components of access licences can be exercised. These dealings are governed by the principles in section 5 of the Act, Minister’s access licence dealing principles, and the rules in this Part.
Note—
Where there is an inconsistency between access licence dealing rules established in this Plan and Minister’s access licence dealing principles gazetted subsequent to the commencement of this Plan, section 71Z of the Act provides for the Minister’s access licence dealing principles to prevail.
47   Rules relating to constraints within a groundwater source
(1)  This clause applies to any relevant dealings under sections 71Q, 71S, and 71W of the Act, and section 71T of the Act with respect to allocation assignments within this groundwater source.
(2)  Dealings are prohibited under this clause if—
(a)  any of the access licences or water allocations involved are not within this groundwater source,
(b)  the dealing would result in the total extraction under access licences through nominated works in the area, plus basic landholder rights extraction, causing any adverse local impact in accordance with Part 10 Division 3 of this Plan,
(c)  the dealing would result in any increase in the total access licence share components nominating works within the Gwydir Watercourse Plan of Management area, as shown in the Plan Map,
(d)  the dealing would result in any increase in the total water allocations credited to access licences nominating works within the Gwydir Watercourse Plan of Management area, as shown in the Plan Map,
(e)  the dealing involves any assignment of access rights from any access licence specified in Schedule 2,
(f)  the dealing involves any water allocation assignments from any access licence specified in Schedule 2, or
(g)  the dealing involves any nomination of works by any access licence specified in Schedule 2, other than those nominated by the licence at the commencement of this Plan.
48   Rules for change of water source
(1)  This clause relates to dealings under section 71R of the Act.
Note—
Section 71R dealings are the mechanism by which access licences can move from one water source to another. Once the change in water source has been effected, if permitted, the new licence will have to nominate specified works (by a dealing under section 71W of the Act) in the receiving water source before extraction can commence.
(2)  Dealings under section 71R of the Act that change the water source to which an access licence applies are prohibited in this groundwater source.
49   Rules for conversion of access licence category
(1)  This clause relates to dealings under section 71O of the Act.

Great Artesian Basin is a ‘confined’ groundwater basin comprised of a complex multi-layered system of water bearing strata (porous sandstone aquifers) separated by largely impervious rock units, underlying largely arid and semi-arid landscapes to the west of the Great Dividing Range, and extending from Queensland through New South Wales and the Northern Territory, to South Australia.
groundwater is water that occurs beneath the ground surface in the saturated zone.
groundwater dependent ecosystems are ecosystems which have their species composition and natural ecological processes wholly or partially determined by groundwater.
long term average storage component is the volume of water in the aquifer less the combined average annual recharge and requirements for basic rights at the commencement of this Plan.
monitoring bore refers to a bore constructed for the purpose of measuring water levels and/or taking samples for water quality analysis.
