Shooters, Fishers and Farmer Party Murray MP Helen Dalton has said her private member's bill to create a public water holdings register could be delayed until the middle of next year.
"In February, I introduced a bill for a state water register, which would also force politicians to declare their water interests," Mrs Dalton said
"The government stalled, stalled and stalled some more to stop the Bill being debated and voted on,"
"They then suspended Parliament until September, meaning my Bill will expire and get thrown out."
"I know under normal circumstances, bills introduced to Parliament expire after six months. But the NSW Government has stopped parliament until September."
Mrs Dalton questioned by bills should expire during a time when Parliament was not sitting due to a crisis and accused the National Party of being "terrified" of her Water Register Bill as it would "expose MPs and corporations profiting from water trading".
The Shooters party collected 11,000 signatures over five months calling "for a federal royal commission into the Murray Darling Basin Plan and the Murray Darling Basin Authority, and the establishment of a Public National Water Register".
Mrs Dalton was later told by the Speaker of the House that an anonymous Nationals MP had objected to the bill on the grounds that Ms Dalton had a conflict of interest, Standing Order 176, which states 'a Member cannot vote on any question in which the Member has a direct pecuniary interest not held in common with other citizens of the State.'
"He or she reported me to the ethics committee. They did everything they could to stop this Bill," Mrs Dalton said.
"Now, they get to throw the Bill out".
Wagga-based Nationals MP Wes Fang said Mrs Dalton's bill and its introduction to Parliament was a matter for the lower house clerks.
"I wouldn't care to really proffer an opinion but the millionaire from Murray should really be focused on the issues ahead of us and stop playing politics with water," he said.
"She is very good with playing politics with issues but the Legislative Assembly has already clarified that water licences should be declared if they have an income greater than $500 per annum.
"She has millions of dollars in water allocations at the moment. I can understand why she is pursuing this register but parliamentarians with water holdings with more than $500 in income should have already declared them on their disclosures.
"We are getting on with the job and talking with the inter-jurisdictions that have control of this and we're looking to establish a national water register and I know the Water Minister has already provided her public support for that."
Mrs Dalton said she planned to re-introduce her Water Register Bill as soon as Parliament resumes, but would have to go through all the formalities again and debate on the Bill could well be delayed until mid-2021.
Wagga MP Joe McGirr has previously backed the Shooters' petition calling for a federal royal commission into the Murray Darling Basin.
"I think a royal commission would go a long way towards clearing up the confusion and mistrust that is dominating public debate in this area," Dr McGirr said in February.
"It would also provide an opportunity to canvas alternative options, if the current plan was found to either not work or could not be made to work."
