Australian Housing Minister Clare O'Neil has been accused of "gaslighting" the public after dismissing fears that proposed government housing tax reforms could lead to substantial rent increases. The minister faced intense questioning on live television regarding predictions that rents could rise by as much as 30 percent.

The concerns were initially raised by Gareth Spence, Head of Australian Economics at NAB, who suggested in a note to clients that changes to the government's capital gains and negative gearing policies could compel landlords to increase rental yields to offset lost tax benefits. NAB later clarified that this was a potential scenario, not a definitive prediction, and assumed dwelling prices would remain unchanged.

Louis Christopher of property analytics firm SQM Research and real estate agency Ray White also voiced similar concerns, predicting rent increases ranging from 15 to 30 percent. These estimates stand in stark contrast to the government's own Treasury analysis, which projects only a $2 weekly increase in rents due to the May Budget measures.

During a tense interview on the program "Sunrise," O'Neil defended the government's Budget estimates. Liberal senator Michaelia Cash criticized the minister's stance, accusing her of "gaslighting Australians" and stating that the government's housing policies were negatively impacting the market and driving up rents.

"Sunrise" host Nat Barr pressed O'Neil, moving beyond the Budget figures to inquire about the broader impact of rising interest rates and the cost-of-living crisis on rental prices. "How much are rents going to go up?" Barr asked.

O'Neil acknowledged that the current rental situation in Australia is not ideal and attributed it to decades of insufficient government action. She emphasized that the government is addressing the problem comprehensively, focusing on increasing housing supply, which she identified as the fundamental issue for renters.

When repeatedly asked if rents would increase by 30 percent, O'Neil reiterated the Treasury's analysis, stating that the impact on rents would be minimal due to the specific way the changes were implemented. She urged renters to consider factual information and advice from rental advocates.

Barr pointed to data showing a significant number of new investor loans, suggesting that landlords might need to raise rents to recoup costs, especially if they can no longer rely on negative gearing benefits. O'Neil, however, maintained that the government's reforms would have a very small effect on rental prices, according to Treasury projections.
