Opposition Leader Angus Taylor rebuked his housing spokesman in Canberra on Thursday for putting a figure on the Coalition's migration policy, a day after Senator Andrew Bragg told the National Press Club that net overseas migration under a Coalition government would be about 180,000 a year.

The policy itself does not contain a number. Under the position Taylor announced earlier this year, the housing minister would report to parliament each year on how many new homes were completed, and that count would become the ceiling for net overseas migration the following year. Bragg's 180,000 was his reading of where the mechanism currently lands.

“Andrew expressed some of his personal views yesterday," Taylor said. "I've made clear to him that his job is to express ... the views of the coalition.”

The arithmetic is checkable. The Australian Bureau of Statistics recorded 43,816 dwelling completions in the March quarter of 2026, seasonally adjusted, in its Building Activity release of 8 July. That was 0.8 per cent higher than the same quarter a year earlier. Four quarters at that rate is a little over 175,000 homes, which is the order of the ceiling the policy would set.

The number the ceiling would be measured against is larger. Net overseas migration was 306,000 in 2024-25, the Bureau reported on 19 December. Arrivals fell 14 per cent to 568,000 and departures rose 13 per cent to 263,000. The peak was 556,000 in the year to September 2023. Federal budget forecasts have the figure falling to 225,000 by 2027-28.

Bragg used his own version of the same gap. "Since Labor came to power in mid-2022, Australia's population has increased by some 1.8 million, of which around 1.5 million has been through net overseas migration," he told the press club. He put the increase in dwelling stock over the same period at 550,000.

The bulk of his speech was about construction rules rather than visas. He committed a Coalition government to replacing the National Construction Code with what he called a Basic Australian Standard covering structural, fire and health requirements, with other provisions made optional. "Our new framework for an 80-page Basic Australian Standard is some 2,000 pages shorter than Labor's NCC," he said.

Housing Minister Clare O'Neil described the speech as a "crazed, almost manic ideological fever dream".

One Nation went lower the following day. The party confirmed its policy is a cap on net overseas migration of 130,000 a year, which its published platform describes as capping visas at that level "to ease pressure on housing, wages, and infrastructure".

Both figures sit against a supply target the country is not meeting. The National Housing Accord commits to 1.2 million new homes in the five years to June 2029, an average of about 240,000 a year, or 60,000 a quarter. Completions have run well short of that since the Accord period began, and commencements in the March quarter fell 11.2 per cent to 48,012, which is the number that sets completions a year or two out.

That is the structural problem with pegging one number to the other. A migration ceiling set by completions moves only when completions move, and completions have risen 0.8 per cent in a year. Whichever way the intake is set, the same constraint is doing the work on both sides of the equation.

The Senate returns on Monday for a four day sitting week.
