The NSW public has a right to know whether a senior government executive, fired over her alleged involvement in the Murray-Darling water theft scandal, received a six-figure payout, the opposition says.
A report into water theft in the Murray-Darling Basin, released on Thursday, confirmed that along with top bureaucrat Gavin Hanlon's public resignation, a second executive was fired for her role in the alleged misconduct.
AAP understands the senior executive is a former National Party staffer and irrigation lobbyist, who was appointed to a senior job within the Department of Primary Industries in 2015.
Opposition water spokesman Chris Minns said the Berejiklian government should confess whether the executive had received a golden handshake on her way out the door.
"The government needs to come clean and tell us how much taxpayer money was handed over to (the executive)," Mr Minns told AAP in a statement.
"This is taxpayer money not Minister Blair's personal piggy bank."
In September, NSW Minister for Primary Industries Niall Blair said misconduct proceedings had started against Mr Hanlon.
Mr Hanlon was forced to resign as the Department of Industry director general in September following allegations of misconduct, including promising to share internal government documents with irrigation lobbyists in 2016.
Thursday's independent investigation into NSW water management and compliance report, authored by Ken Matthews, said the second senior executive is alleged to have also been involved in the teleconference.
According to her LinkedIn profile, the executive was a policy officer for lobby group Southern River Irrigators between 2011 and 2013 before becoming an advisor to federal senator Simon Birmingham for a year.
A Department of Industry, Crown Lands and Water spokeswoman told AAP some employees were entitled to receive a "termination payment".
"Employees whose employment is terminated may be entitled to receive a termination payment in line with the conditions set out in the Government Sector Employment Act," the spokeswoman said.
Thursday's report comes less than a week after both NSW and Queensland were slammed by a Murray-Darling Basin Authority (MDBA) review into water theft and regulation.
That inquiry found both states regularly failed to make sure irrigators complied with the Murray-Darling Basin Plan, and weren't transparent about their failures.
A day after the MDBA report was handed down, South Australian Premier Jay Weatherill announced a royal commission into water theft in the basin.
