Australians with evidence of corruption have been urged to share it with crossbenchers in federal parliament, who have no hesitation airing their claims.

A swag of crossbenchers have made the appeal while pressuring the government to create a corruption watchdog with real teeth, amid concerns a probe into Crown Resorts by a little-known agency won't address key allegations.

Senator Jacqui Lambie says people who have lost trust in politicians from the major parties can turn to the crossbench, who are protected from legal action over what they say in parliament.

"I want the people of Australia to know this: we have no fear and we have the advantage of privilege in the chamber," she told reporters in Canberra on Wednesday.

"If you have got documents you want to produce to us, and you don't want to be named, I'll tell you what, we have no fear in standing up in the chamber and calling them out for what is going on here."

Attorney-General Christian Porter is currently drafting a bill to establish a federal integrity commission.

It is expected to be completed by the end of the year before being subjected to a "robust consultation phase".

The crossbenchers believe if the commission was in place now, it would be the appropriate body to consider allegations involving Crown and government agencies.

The gambling giant is facing claims it had a "hotline" to Australian consulates to fast-track visa applications for high rollers flying in from China.

There are also allegations Crown laundered large sums of money through its Melbourne gaming venue, which the company strongly rejects.

Mr Porter has tasked the Australian Commission for Law Enforcement Integrity with investigating the issue, but Tasmanian MP Andrew Wilkie says its limited powers mean the watchdog will miss key elements.

"ACLEI will not look at the behaviour of Crown, ACLEI will not look at the conduct and behaviour and allegations about politicians in this place," he told reporters.

Mr Wilkie said it was self-evident things "stink" in parliament.

"I'll go so far to say there are corrupt politicians in the federal parliament, and they're scared stiff of an integrity commission."

Newly-elected crossbenchers Zali Steggall and Helen Haines said community members were forthcoming with their concerns on the campaign trail.

The crossbenchers are pushing for an anti-corruption body that is well funded, able to hold public hearings and accept complaints from the public.

Under the government's current plan, the watchdog will have two arms, one focused on law enforcement and the other on the public sector, with only the first able to hold public hearings.

The public sector division would investigate and refer potential criminal conduct to the courts, where findings could then be made public.

Mr Porter said the experience of state-based corruption bodies showed it is the worst possible area to make "policy on the run".

"This is one area where the hard detailed work must come before the headlines," he told AAP.

"The coalition is doing the hard work to get the model right.

"As a result, Australians can have confidence that an appropriate mechanism will be in place to detect and prosecute corrupt or criminal behaviour by all commonwealth employees."

Labor lashed out at the Liberal Party, saying Australians have heard nothing about the impending integrity commission since it was announced in December.

"Apparently that's now back to the drawing board, or perhaps it's in the waste paper basket. That's how much this government thinks of integrity," shadow attorney-general Mark Dreyfus told parliament.
