Analysis of Possible Rules for Interstate Water Trading by the Australian Capital Territory

Rules will be studied and modelled for allowing ACT water trading with other states, within an agreed abstraction cap. The aim is to find administrative, constraining and price-setting rules that maximise the economic gain of trading to Australia, bearing in mind environmental constraints, infrastructure costs, transaction costs, and equity. Innovative challenges for the rules will be allowing ACT to sell water now but buy it back later, thus providing for long term population growth; and handling the differences between ACT's spare storage capacity and urban uses, and the downstream irrigation uses with which trade is most likely.
