Despite politicians and lobby groups opposing Helen Dalton's water register bill, the Member for Murray believes it's "on the right track".
Mrs Dalton's water register bill was the focus of hearings during a state parliamentary inquiry.
The hearings heard that the bill would force politicians to declare their water interests and create an online water register,
The register was labelled as an invasion of privacy and a waste of time by those in opposition.
However, Mrs Dalton is determined her bill remains on track and insisting that the strong opposition has only highlighted those who she says have something to hide.
"When 11,000 members of the public sign a petition for a water register and all the powerful groups try and stop it, you know you are on the right track," Mrs Dalton said.
"People who have nothing to hide, hide nothing.
"This shows why we need a water register."
Former National Party water ministers Kevin Humphries and Katrina Hodgkinson, current water minister Melinda Pavey, Griffith mayor John Dal Broi, NSW Farmers and the NSW Irrigators Council were among those who fronted the inquiry.
"Some called it a waste of time, others called it an invasion of privacy," Mrs Dalton said.
"But they all seem to want my bill to disappear."
A key claim of groups like NSW Farmers and the NSW Irrigators Council was that a water register would lead to Aussie Farm-style 'terrorist' attacks on irrigators.
"This is absolute rubbish. I'm an irrigator. Anyone who walks past my farm already knows I own water," Mrs Dalton said.
"A water register would expose the Sydney traders and foreign companies who own water, not farmers.
"We already have a land register, but a water register seems to terrify a lot of powerful people.
"I wonder why?"
Water researcher Maryanne Slattery and Southern Riverina Irrigators vice-chairman Darcy Hare were among the few who expressed support during the hearings.
Mrs Dalton believes the widespread hostility toward the bill proves it is needed.
The inquiry will present recommendations to NSW Parliament on the bill in September.
Both Mrs Dalton and Ms Pavey have bills before the parliament which they both claim will improve transparency in water trading and ownership.
