Buildev co-founder Darren Williams wanted former ministers Mike Gallacher and Chris Hartcher to set up a meeting with the now Premier Mike Baird about one of the company's proposals, an inquiry into corruption has heard.

Mr Williams was asked at the Independent Commission Against Corruption (ICAC) about an email he sent to Nathan Tinkler before the last election about Buildev's plans to build a coal loader at Mayfield in Newcastle.

"Spoke to Mike Gallacher this morning, he's ready to go post election," it read.

Counsel assisting Geoffrey Watson SC asked Mr Williams if that meant Mr Gallacher was ready to start mobilising support for the project once the Coalition won government.

But Mr Williams said it just meant he was willing to have the proposal put through proper processes.

"He wouldn't have said he was ready to go, that would be my words," he said.

The inquiry heard after the election Mr Williams sent a text message suggesting Mr Gallacher and Mr Hartcher needed to get the new treasurer, Mr Baird, briefed on the coal loader as soon as possible.

Mr Watson put it to Mr Williams that he felt he could ask Mr Gallacher and Mr Hartcher for a favour.

"You did this because you knew that Buildev had made payments to Eightbyfive which had benefit to both Mr Gallacher and Mr Hartcher?" Mr Watson said.

Mr Gallacher's barrister Arthur Moses furiously objected to the suggestion, saying there was no evidence whatsoever that his client benefited from the EightbyFive fund.

The inquiry previously heard allegations that Buildev and Mr Tinkler's other companies channelled tens of thousands of dollars through the alleged slush fund, which had been set up by a staffer or Mr Hartcher.

There is no evidence that a meeting between Buildev and Mr Baird ever eventuated.

The inquiry claimed another Liberal Party scalp yesterday, as Londonderry MP Bart Bassett became the ninth member to be dragged into the scandal into alleged political donations.

Commissioner Megan Latham announced new evidence had emerged to widen the inquiry's scope to examine whether Buildev tried to influence Mr Bassett.

Mr Baird said he could not believe what was happening at the inquiry and was disappointed.

"I'm obviously not going to provide a running commentary on ICAC but I can assure you we've taken action, very strong action, and we'll continue to take strong action," he said.

"We're not accepting, in any way, anything that we are seeing emerge out of ICAC. If we need to take action we will."

The Premier would not say whether he has spoken to his MPs about the corruption allegations.
