The Indi MP will introduce the bill in the House of Representatives on Monday.

The government has the power to leave it there with no action, but Dr Haines is hopeful that by early December, she could get support needed to at least have a debate.

While the states have their own integrity commissions, to investigate corruption by public servants, there is not one on a national level.

"There has been actually in the last week, since I've been talking about this much more... a steady stream of people approaching me now asking about my bill," Dr Haines told The Border Mail.

"Quite a few people have indicated to me that they are willing to cross the floor to bring on debate - that's a big move for them to do.

"It doesn't mean they would necessarily vote in favour of my bill, but that they are really strongly in favour of us finally (having the debate) - because we have never had a debate in the House of Representatives on a federal integrity commission bill."

Attorney General Christian Porter has said the federal government wanted to conduct consultation around its draft integrity legislation, but not during the worst of the coronavirus pandemic.

The MP's bill has received extra attention since revelations at NSW's Independent Commission Against Corruption about the relationship between Premier Gladys Berejiklian and former Wagga MP Daryl Maguire.

Although this has increased public interest in the possibility of government corruption, Dr Haines said "any day is good timing to introduce a federal integrity commission".

"What I think the last couple of weeks have demonstrated are just more examples of why we absolutely need one," she said.

The examples also included senior Australia Post employees being gifted gold watches, the federal government paying more money than land was worth for a future airport in Western Sydney, and the ongoing sports rorts scandal.

"It just goes on and on, the list just gets longer and longer," Dr Haines said.

"Many things are converging this week about the need for a federal integrity commission - that is very timely for me introducing to the Parliament this new bill."

One of the sticking points for MP is the push for public hearings, but Dr Dr Haines said "hearings behind closed doors don't engender public trust - the nation has told us that time and time again."

"I think we need to have an integrity commission that has a common set of rules for everyone, whether you're a Member of Parliament or a staffer or departmental head or whether you're a member of the Australian Federal Police," she said.

"If there is a serious, systemic allegation of corruption, there needs to be a public hearing so the public can then see for themselves whether a fair process has been undertaken. It is a sticking point for the government though - they do not want public hearings for MPs or their staffers.

"I think that just simply doesn't pass the pub test with everyday Australians."
