The finding, published in The Age, casts doubt on the party's central campaign claim that it can lower taxes, make housing more affordable and rebuild the state's finances if it wins government on November 28.
One Nation's "The Real Deal" policy platform pledges to wind back land tax increases introduced after the pandemic, raise the threshold at which small businesses become liable for payroll tax, and abolish stamp duty on insurance. In a separate Instagram post, the party also promised to abolish payroll tax for regional employers, a measure not mentioned in its published policy document.
Senator Pauline Hanson and Victoria's One Nation state leader Warren Pickering say these tax cuts, along with a long list of law and order promises including three new magistrates' courts, 30 extra magistrates, a 24/7 bail court, additional funding for prosecutors and Legal Aid defenders, and sign-on bonuses for experienced police, will be paid for by cancelling the Suburban Rail Loop and repealing the laws that enact the statewide treaty.
The party provided no details for its planned land tax or payroll tax changes, no costings for any of its policies, and no responses to questions from The Age, despite its policy document promising to be "honest about the numbers" and tell the truth about what the state can afford.
Property experts have separately warned that One Nation's prescription for Victoria's housing crisis will do little to improve affordability and could worsen the chronic shortage of new homes.
The party is currently attracting the support of 20 to 25 per cent of respondents in published polls.
