Former NSW premier Mike Baird has told the state's corruption watchdog he only ever witnessed his successor Gladys Berejiklian act impartially toward disgraced MP Daryl Maguire, who he described as "certainly aggressive and at times abusive" to staff.
Mr Baird told the Independent Commission Against Corruption he was "incredulous" Ms Berejiklian, a close personal friend, was in a secret relationship with Mr Maguire.
The commission is investigating whether Ms Berejiklian breached public trust by not disclosing the relationship and whether she "was liable to allow or encourage" Mr Maguire's conduct in securing grant funding.
"I think it should have been disclosed," Mr Baird said of the relationship.
He said he thought the "potential conflict of interest" could have been managed had he known about it.
He said Mr Maguire was someone who "relentlessly pursue his own agenda".
"At times, he was certainly aggressive," Mr Baird said. "And, I think, at times, abusive to members of staff, to public servants and MPs."
Some $5.5 million was set aside for the Australian Clay Target Association in Wagga Wagga in Mr Maguire's electorate after a meeting of cabinet's Expenditure Review Committee, which Ms Berejiklian chaired, in December 2016.
Mr Baird said he supported the project but that he thought the proposal needed "significant work".
"I put my concerns and what I thought was needed and that was endorsed by the [expenditure review] committee," Mr Baird said.
Nigel Blunden, the former director of strategy to Mr Baird, was asked by ICAC earlier on Wednesday about emails in which he was derisive about the project, calling it the "Maguire international shooting centre of excellence".
He began a memo on the project: "As Joel Goodson [Tom Cruise's character in the film Risky Business] would say, sometimes you gotta say WTF."
Mr Blunden agreed on Wednesday that he said this in jest.
The memo said "Gladys and Ayres want it", referring to Ms Berejiklian and then-sports minister Stuart Ayres.
It details that it was suggested they should "go away, test the assumptions, verify the business case and then come back when it's solid". It then notes the proposal was taken off the agenda, "but Daryl fired up and Gladys put it back on".
Mr Blunden told the ICAC Mr Maguire "had every right to advocate" for funding, but his own "overwhelming concern" was about the urgency while there was not a rigorous business case.
"It was just a case of is this really the most appropriate expenditure of $5.5 million of taxpayers' money?" Mr Blunden told the commission.
Counsel assisting the ICAC, Scott Robertson responded: "To summarise, WTF."
The inquiry prompted Ms Berejiklian's resignation earlier this month, and she has denied any wrongdoing.
Earlier this week, two senior public servants who worked at the Office of Sport testified there were questions raised by Mr Baird's office in 2016 about the grant.
Paul Doorn, a former executive director in the state's Office of Sport said there was "a lot of push" from Mr Maguire to get funding, and if he'd known about the personal relationship it would have been a "red flag".
The next witness ICAC will call on is Chris Hanger, a deputy secretary in the Department of Regional NSW.
