One Nation leader Pauline Hanson has built significant political momentum on a promise to slash Australia's migrant intake to 130,000 visas a year — a figure that polling suggests resonates with more than a third of Australian voters, more than any other party on the issue. But when the numbers behind that policy are scrutinised, immigration and economics experts say the plan is riddled with legal obstacles, structural contradictions, and potentially serious consequences for the economy.

What One Nation Is Actually Proposing

Hanson's headline policy is a hard cap of 130,000 visas per year across all categories. The proposal does not clearly specify whether this applies to temporary visas, permanent visas, or both — though Hanson has previously indicated the figure relates to arrivals. For the purposes of expert analysis, the cap is taken to include both temporary and permanent visa holders arriving from offshore, excluding visitor visas.

To understand why that target is so difficult to hit, it helps to understand how Australia actually measures migration. The official metric is net overseas migration (NOM) — the number of people arriving for long-term stays minus those who leave. In 2022–23, NOM reached a record 538,000 following the reopening of borders after the COVID-19 pandemic. It has since eased to 429,000 in 2023–24 and 306,000 in 2024–25.

The vast majority of people driving those numbers are on temporary visas — international students, working holidaymakers and skilled workers. In 2024–25, around 363,000 temporary visa holders entered Australia while 148,000 departed. Permanent visas, capped at 185,000 places, play a smaller role in NOM since most recipients are already living in Australia when they receive permanency.

The Legal and Practical Barriers

Even setting aside the scale of the cuts required, experts point to significant legal and structural barriers that would make the 130,000 cap almost impossible to enforce as stated.

Former immigration department deputy secretary Abul Rizvi notes that the government does not have legal powers to cap visas for spouses and dependent children. If family visas are kept at current levels — roughly 44,000 places — and Pacific Australia Labour Mobility (PALM) scheme workers (about 33,000 per year) are exempted as Hanson has suggested, that leaves only around 86,000 remaining places for students, skilled temporary workers, temporary graduates, working holidaymakers and New Zealanders combined.

In 2024–25 alone, Australia issued approximately 234,000 student visas to offshore applicants, 126,000 temporary graduate visas, 321,000 working holidaymaker visas, and 130,500 temporary skilled visas. Fitting even a fraction of those categories into 86,000 spots would require extraordinary — and in some cases legally questionable — intervention.

Then there is the question of New Zealand. Under the Trans-Tasman Travel Arrangement, New Zealand citizens are automatically granted visas on arrival and may live and work in Australia indefinitely. There were 1.98 million arrivals from New Zealand in 2024–25, though it is not immediately clear how many stayed long-term. Rizvi was blunt: "I don't know how Hanson proposes to deal with NZ citizens and the Trans-Tasman Travel Arrangement. She may not have thought about it."

Australia also maintains working holidaymaker arrangements with multiple countries that allow for uncapped places — another structural hurdle to any hard visa ceiling.

What It Would Mean for the Economy

Experts warn that if the cap were somehow enforced as proposed, the result would likely be negative net migration — meaning more people leaving Australia than arriving. That outcome, they say, would damage industries that depend heavily on migrant labour, and could push the country deeper into debt by shrinking the workforce and tax base that fund public services.

The gap between the political appeal of Hanson's migration pledge and its practical feasibility remains wide — and as the federal election cycle intensifies, that gap is likely to face growing scrutiny.
