2.63 The states and territories concerned have passed laws to refer powers to the Australian Parliament, which then relied on these references to support a number of reforms implemented by the Water Amendment Act.  2.16 After the Water Act came into force, the Commonwealth, NSW, Victoria, SA, Queensland and the ACT concluded a declaration of intent regarding the basin at a COAG meeting in March 2008.  It was agreed to apply other cooperation agreements for water management in the basin, which are part of the agreements established under the Water Act, particularly on issues for which the Australian government did not have the constitutional authority to legislate.  The Intergovernmental Agreement on a National Water Initiative (2004) is an agreement between the Commonwealth, New South Wales, Victoria, Queensland, South Australia, the Territory of Australia and the governments of the Northern Territory. The agreement is a joint commitment to increase the efficiency of Australian water consumption, increasing investment security and productivity. 2.23 The Australian government has also taken non-legislative measures to implement water reform, including water buybacks. The Memorandum of Understanding signed on 2 November 2012 MOU) is an agreement between the State of Maharashtra and the State of New South Wales to facilitate mutually beneficial cooperation and encourage trade and/or investment in: A drilling rehabilitation concept was proposed as part of the strategic management plan of the Great Artesian Basin 2000 and led to the development of the Sustainable Development Initiative Program for the Great Arterial Basin (GABSI). This program has been made available in partnership by the governments of Australia, New South Wales, Queensland, South Australia and the Northern Territory to provide financial assistance for repairs to uncontrolled drilling. The agreement, in force since 2003, provided a useful cross-border strategic obligation in the water field, which influenced the content and nature of subsequent water planning and management decisions for both states. 2.12 In 1994, the Council of Australian Governments (COAG) adopted a strategy for effective and sustainable reform of water management in Australia.  This strategy improved further in 1996.  In 2004, COAG approved an intergovernmental agreement on a National Water Initiative (NWI).
 Through the NWI, the Commonwealth, states and territories have agreed on the importance of meeting the water needs of rural and urban communities, while ensuring the health of river systems and groundwater.
