Disgraced former Liberal MP Daryl Maguire gave Louise ­Waterhouse the personal email address of NSW Premier Gladys Berejiklian to help fast-track approval for an infrastructure decision she was after but urged her not to mention him because it would be “ICACable”.

The Independent Commission Against Corruption heard Mr Maguire tried to lobby several NSW ministers, including Ms Berejik­lian, on behalf of Ms Waterhouse and her Smart West Sydney development project near the Badgerys Creek airport.

The inquiry, in its 11th day of hearings, is investigating Mr Maguire, who resigned after alle­gations surfaced ahead of the 2018 state election, over claims he misused his parliamentary position to pursue his and his business associates’ financial interests.

After multiple failed attempts to garner parliamentary support, Mr Maguire sent Ms Waterhouse the Premier’s personal email address in November 2017, telling her to “rub her ego” as she sought to overcome the “bureaucratic gridlock” that was scuppering road plans for her development.

“All right, this is what you’ve been trying to do and — these ­people are getting in your way. Just kill them, just off with their heads. Take no prisoners,” Mr ­Maguire told Ms Waterhouse in an intercepted telephone ­conversation.

“Actually you prob, you, you probably better off not to dob me in it. Just send it to her OK? I’ll just, I’ll walk down and tell her … well the fact all that stuff is ICACable.”

“Freedom of Information or whatever,” Ms Waterhouse replied.

The daughter of Sydney bookmaker Bill Waterhouse denied any wrongdoing, describing the conversation as “silly talk”.

She also rejected the allegation she asked William Leong, the property developer trying to broker the sale of the development, “Who would take care of Daryl?” — a reference to the $690,000 fee Mr Maguire ostensibly stood to gain from the sale.

“I saw him as a very good member of parliament,” Ms Waterhouse told counsel assisting the inquiry, Scott Robertson.

“He (Mr Maguire) told me he didn’t stand to gain.”

In two emails to Ms Berejiklian, which Mr Maguire allegedly proofread before they were sent, Ms Water­house asked the Premier to look at an engineer’s review of the design of the intersection, so she could be “independently and properly informed” about the planned location.

“I hope you don’t mind my taking the liberty to send my attached letter to you directly — about an urgent need to future-proof important infrastructure in Sydney’s west — which greatly concerns me and I believe will concern you too,” she wrote.

The corruption inquiry also heard from property developer Joseph Alha, whom Mr Robertson questioned over his role in trying to influence appointments to the Independent Hearing and Assessment Panel — the body that oversaw development approvals.

In intercepted telephone calls, messages and emails tendered as evidence, Mr Alha and Mr Maguire discussed several applicants for the panel, whom they described as “very bad news” — ­ people Mr Alha believed would negatively impact his development planning proposals.
