Indi MP Helen Haines believes support for her proposed integrity commission has increased following Christian Porter's resignation from federal cabinet.
In announcing Mr Porter's move to the backbench, Prime Minister Scott Morrison said the former Attorney General's decision to resign upheld the Ministerial standards.
But Dr Haines said the same questions remained about the blind trust that supported Mr Porter's legal action against the ABC whether he was on the frontbench or not.
"If it's unacceptable for a Minister, it's unacceptable for an MP too," she said.
"If the PM had kept his election promise and established an ICAC, the facts about Mr Porter would be on the table."
Dr Haines told The Border Mail there were "good members of the government who have been watching and waiting for two years for their own Prime Minister to lead them into establishing a federal integrity commission". Asked about those members of government, Dr Haines said she hadn't spoken within anyone in recent days but named MPs in both houses of Parliament who had been working on the integrity bill.
"So there's many, many members of the cross-bench and of the government who've all engaged with me in writing the Australian Federal Integrity Commission Bill, and I know they're very keen to see an integrity commission established," she said.
"They (government members) were waiting on their own team to introduce a piece of legislation into the house, but that hasn't happened, so I'll certainly be calling on them when I get back to Canberra in October to support me in bringing on debate of the bill in the house."
The government voted down Dr Haines' move to suspend standing orders to debate the integrity body in August, after the Indi MP first introduced the bill in October, 2020.
"You never know until the bills ring who will do what - but I call on any member of of a large party to vote with what their constituents want them to do," she said.
"In every piece of polling that's been undertaken in recent times, the support for an integrity commission is always upwards of 80 per cent.
"This is not a new idea; this is a popular idea, and one that was promised to the nation more than 1000 days ago."
In addressing media about Mr Porter's resignation from his Ministerial position, Mr Morrison said it was a different issue whether he should remain an MP.
"The issue for the Prime Minister is about whether a Minister is in a position to ensure that he can satisfy himself that he doesn't have a conflict of interest, perceived or otherwise. And, so, the Minister has taken a decision which respects that standard," he said.
