Major irrigation systems on the Victorian side of the Murray River have received further allocation increases, but general security allocations in New South Wales remain at zero per cent.
The Victorian Murray system moves from 71 per cent of high-reliability water shares to 78 per cent HRWS.
The Goulburn system and the Loddon system increase from 56 per cent HRWS to 70 per cent HRWS.
The seasonal determination in the Broken system increases from 4 per cent HRWS to 9 per cent HRWS.
The Bullarook system increases from 69 per cent HRWS to 100 per cent HRWS and 25 per cent of low‑reliability water shares.
The Campaspe system remains at 100 per cent.
Resource Manager Mark Bailey said the improvements came from more water reaching the major storages than was estimated.
"Flows into the major storages have been higher than anticipated in the last fortnight, even without significant rainfall," Dr Bailey said.
Dr Bailey noted the climate outlooks continue to favour drier conditions.
