Calls are growing for the government minister at the centre of the $100 million sports grant scandal to step down.
Labor, the Greens, One Nation and independent MP Zali Steggall have all called on National Party deputy leader Bridget McKenzie to resign.
An independent review found while Senator McKenzie was sports minister she awarded most of the grants to seats being targeted by the coalition during the election last year.
One Nation will support Labor and Greens' calls for a senate inquiry into the scandal, with Greens leader Richard Di Natale saying "enough is enough".
"We need an enforceable ministerial code of conduct to end the use of public funds for blatantly political purposes," Senator Di Natale tweeted.
Ms Steggall said the coalition's politicisation of the community sports grant program was "disgusting".
"She's completely lost if she doesn't think she needs to acknowledge that there's something wrong with cheating kids and community sports clubs," the independent MP for Warringah told ABC radio on Friday.
Senator McKenzie is refusing to apologise, insisting no rules were broken.
Labor leader Anthony Albanese said then-Labor sports minister Ros Kelly resigned when she was embroiled in a similar controversy in 1994.
"The minister resigned and I suggest this minister needs to resign as well," Mr Albanese told reporters in Sydney.
He said Senator McKenzie's position was untenable and pointed to the allegedly forged documents scandal surrounding Energy Minister Angus Taylor.
"It seems that there is nothing that any minister can do in Scott Morrison's government that warrant them considering their position," Mr Albanese said.
Ms Steggall took aim at the prime minister and compared him to former Australian cricket captain Steve Smith, who served a one-year ban for failing to stop cheating within the team.
"The standards of the members of your team, they're a direct reflection on the standards of you as a captain," Ms Steggall said.
"It's just quite concerning that is what they think is acceptable conduct.
"We really need a national integrity commission ... how low are you prepared to let the standard drop."
One Nation leader Pauline Hanson said she'll back calls from Labor and the Greens for a senate inquiry into the scandal.
"If it's going to prove they've used that money, taxpayers' dollars, to feather their own nest and further themselves, yes, I do," Senator Hanson told ABC on Friday.
She said Senator McKenzie needed to resign.
Senator McKenzie found support from frontbench colleague Peter Dutton who said she shouldn't have to resign.
"None of those clubs that received that money have been found ineligible," Mr Dutton told the Nine Network.
"I've been in the parliament a little while, I can remember the years in opposition where the Labor minister, the Labor candidate, the Labor senator, would come out and make announcements for funding in your local community.
"This isn't anything new in that sense."
