One Nation Leader Pauline Hanson will withhold support for all government legislation unless the Prime Minister backs her bill to stop mandatory vaccinations.
Ms Hanson will introduce her legislation in the Senate tomorrow which seeks to make it unlawful to discriminate against Australians who choose not to be vaccinated against COVID-19.
It comes as the states are making vaccination mandatory in many workplaces as they start to open up.
The One Nation leader told the Prime Minister if the federal government does not back her bill tomorrow, she with withhold her vote on all government legislation.
This will mean the Morrison government will not be able to pass any laws in its final two weeks in parliament for the year.
