On Friday The Australian Financial Review reported the government may abandon or delay plans to introduce legislation for an anti-corruption commission "amid fears it has lost control of the senate".

It is believed at least two Liberal senators have threatened to withhold their votes to protest vaccine mandates, as has Pauline Hanson.

The government took promises of establishing a federal watchdog to the 2019 election.

IN OTHER NEWS:

Dr Haines, whose own Australia Federal Integrity Commission bill is before the senate, said the reports underscore the fact the government has never been serious about establishing a strong federal integrity commission.

"They are afraid of this, they've done everything in their power to avoid it," she said.

"We're coming to the end of the 46th parliament, we're at the last two sitting weeks of the year, and the government haven't even been able to put forward a piece of legislation.

"The fact that they're not going to do that in the next weeks just says... they have vacated the integrity space."

"They're completely ignoring the wishes of nine out of 10 Australians who are calling for a strong integrity commission."

Dr Haines said her own bill had been "lauded as the gold standard" by legal experts.

"If the government was serious about wanting to fulfil their election promise on an integrity commission, they would either introduce their own legislation or debate my bill," she said.

"They don't want to do either."
