Another Government politician has vowed to withhold support from Scott Morrison unless action is taken to stop vaccine mandates.
George Christensen, the LNP member for Dawson, said he will not follow Government directions on how to vote in the lower house.
It comes after five Coalition senators crossed the floor and voted to support Pauline Hanson's bill to end vaccine discrimination before it was comfortably voted down.

The Government has a wafer-thin majority in the lower house where it controls 76 out of 151 seats, meaning Mr Christensen has the potential power to bring down Government bills.
The outgoing MP, who will not contest next year's election, has been campaigning against vaccine mandates for months.
In a blog post on Monday, he explained he's told Nationals leader Barnaby Joyce of his decision to potentially withhold his support for the Government.
'To be clear, until federal action is taken against vaccine discrimination, I will be voting according to my conscience (or abstaining from votes) on bills and substantive motions rather than just voting with the government as MPs usually do,' he wrote.

'As I was elected as a member of the Liberal National Party, I will continue to support the government with confidence motions and supply as well as procedural motions (except if they relate to ending vaccine discrimination).
'My support is not guaranteed on bills or substantive motions. When action is taken to stop vaccine discrimination, I will go back to the normal process of voting with the government on most, if not all, bills and substantive motions.'
Mr Christensen said he feared his stance would 'result in personal attacks on me.'
'But far more important than my political and personal reputation is the prospect of ending the tyranny, the discrimination, the segregation, the job losses and the negative business impacts that are all being wrought (or are about to be wrought) on my fellow Australians,' he wrote.
The Federal Government insists the Covid vaccine is optional but state and territory governments as well as private companies have enforced vaccine mandates, requiring jabs for activities like going to work, the pub or the shops.
On Monday One Nation leader
