Rules and restrictions

A number of rules and restrictions govern the trading and transfer of water rights. These rules are established under regulation by Australian government, state and territory governments, through inter-governmental bodies and agreements and by private irrigation organisations. These rules can act to both facilitate and restrict trade. They relate to changes in location/ownerships of water entitlements, water allocations, irrigation rights, water delivery rights and the circumstances under which these rights can be traded.

The rules and restrictions are established through a variety of administrative instruments. All states and territories have underlying legislation that provides a legal basis for the establishment, administration and/or enforcement of rules and restrictions.

The list below summarises the sources of rules and restrictions in each of states and territories and also rules operating across jurisdictional boundaries. For further information click the links below or seek advice from your local water authorities.

Rules for water trading in the Murray-Darling Basin are currently being reviewed as part of the Murray-Darling Basin Plan development. For further details see the Murray-Darling Basin Authority's web site . This section will be expanded once the Murray-Darling Basin Plan is finalised.

Allocation limit Environment Allocation Amount of water that can be made available for consumptive use in a particular defined area or water resource under the rules specified in the water resource plans. This affects the volume of water available for trading. Tick Tick Tick Tick Tick Tick Tick Tick
Refer to the allocation announcements in Water allocations and rules specified in the Water Resource Plans in Water trading rules below
Basin cap Environment Allocation Applies a limit on the amount of water that can be diverted from the Murray-Darling river system for consumptive uses (agricultural, industrial or domestic purposes). This limit impacts the amount of water available for consumptive use, hence the water available for trading. Tick Tick Tick Tick Tick Cross Cross Cross
The Cap is managed in accordance to the rules specified in Schedule E of the Murray–Darling Basin Agreement which is Schedule 1 of the Water Act 2007.
Barmah Choke Physical Allocation The Barmah Choke imposes a channel capacity constraint to the volume of water that can be supplied to the lower reaches of the River Murray (limit on upstream water to be traded downstream). The channel is narrow and the maximum flow that can pass through is about 8,000 ML per day. Tick Tick Cross Tick Cross Cross Cross Cross
Connectivity of the water systems Physical Allocation Water can only be traded between water supply schemes that are hydrologically connected. Tick Tick Tick Tick Tick Tick Tick Tick
Refer to Water resources for information on the water systems and see the relevant administrative instruments for your jurisdiction below.
Carryover arrangements Volume Allocation This is the maximum amount of unused water that can be carried over from one year to the next within specified limits, usually subject to volume and time limits as well as usage restrictions. This may be useful in helping water users plan their water requirements or sell their excess water. Tick
Carryover rules are specified in the water resource plans for each state and territory.
