A Shooters, Fishers and Farmers MP who owns more than $17 million of water entitlements in the Murray-Darling basin wants to force politicians to disclose their water interests.

Murray MP Helen Dalton, an irrigator who owns a farm 40 kilometres from Griffith, is preparing a bill that makes such disclosures mandatory, establishing an online water register that allows the public to look up the water entitlements of individuals, investors, foreign companies, and government departments.

“State MPs are making key decisions that impact on the supply and price of water. If they own water themselves, the public have the right to know about it," she said.

A critic of the Murray-Darling Basin Plan and the Berejiklian government's water policies, Mrs Dalton campaigned heavily on water issues in the lead up to the March election, when she won the south-western NSW seat from the National Party.
