I caught a grab on TV last night about Rudd and Wong spending $303million to return water to five NSW river systems under the Restoring the Balance in the Murray-Darling Basin program. A figure of 240 gigalitres was mentioned.
Digging around I find that the Twynam Agricultural Group, the nation’s largest private water holder, has sold general and supplementary water licences to five systems—the Gwydir (63.5GL), Barwon (14.6GL), Macquarie (41GL), Lachlan (52.3GL) and Murrumbidgee (68.4GL). The NSW Government reacted to the sale by placing an embargo on any further buybacks in the state and demanded that Victorian irrigators be called on to sell their share of water licences.
Two points can be made. Removing Twynam’s allocation from the system does mean more water over the long-run for environmental flows. However, these licences have yielded, on average, 107GL of real water—or less than half the 240GL entitlement—each year. Climate change may well reduce that amount to less than 100GL in public hands. Though little of that water will make its way to South Australia and to the lower lakes and the Corong, it will help give the Gwyder and Macquarie wetlands a drink.
Secondly, this buyback by the Commonwealth is addressing the bad policy by the NSW state government, which over-allocated the water in the first place--- in the 60s and 70s under Wal Murray-- and which has failed, nay refused, to claw back the over-allocations of water priced far too low. They have ducked the issue of subsidizing irrigated agriculture that trashed the environment.
This is happening at a time when the Victorian state government is building a pipeline to take 75GL for Melbourne. Rudd, Wong and Garrett say nothing. How can taking more water from the River Murray be a good thing? The Commonwealth is saying that health of the Murray-Darling Basin is in decline that available water is currently over-allocated, and this problem is likely to become worse as water availability declines due to climate change.

Twynam sold their water licences because they were yielding a poor rate of return. The company is getting out of rice and cotton, and they got a pretty good deal for selling their licences.
