PAULINE HANSON | 'Australian homes for Australians only'

"Foreigners who aren't Australian citizens shouldn't own Australian homes," Senator Hanson wrote, in the kind of unvarnished statement that has long been her political signature.

The post drew an immediate and passionate response from both sides, with thousands weighing in on whether the policy would do anything to ease Australia's punishing housing affordability crisis or simply score political points.

Among those who backed the call were renters and would-be first homebuyers who said they felt locked out of the market entirely.

One commenter, a 40-year-old father of two, said One Nation represented his family's only realistic hope of ever owning a home.

"We've both always worked our backsides off and saved," he wrote.

"But the goalposts keep shifting."

Others went further, calling for restrictions on temporary residents, international students and overseas investors.

One commenter arguing Australians should not be "living out of tents and vehicles" while non-citizens occupied housing.

But the pushback was equally forceful and it came armed with data.

Foreign ownership of Australian residential property is, by most measures, a marginal factor in the housing crisis.

Property sales figures consistently show non-citizen buyers account for around one per cent of annual transactions, a number that critics say renders Senator Hanson's proposal more symbolic than substantive.

"Australia's housing crisis won't be solved by banning foreign buyers who own less than one per cent of purchases," one commenter argued.

"It's about supply shortages and domestic investor incentives."

"Blaming non-citizens divides society without addressing the root causes."

Others pointed out that foreign investment can actually support property values and that a blanket ban could hurt existing homeowners as much as it might help aspiring ones.

Several commenters argued the only meaningful fix was building more homes, with one noting that ownership restrictions did little to shift the fundamental equation of supply and demand.

Senator Hanson did not attach any modelling or projections to her post, leaving unanswered the question of how many additional properties a non-citizen ban would actually return to the market.

The post comes as housing affordability remains one of the most politically charged issues heading into the federal election cycle.
