A record 510,000 people came to Australia in the year to June 2023, but the minister said her government would “bring numbers back under control” and reduce the annual migration intake by around 50%.

Among the new measures are tougher minimum English-language requirements for international students, and more scrutiny of those applying for a second visa – they must prove that any further study would advance their academic aspirations or their careers. There are some 650,000 foreign students in Australia, with many of them on their second visa, according to official data.

The visa pathways for migrants with “specialist” or “essential” skills – like highly-skilled tech workers or care workers – have also been improved to offer better prospects of permanent residency.

The new policies will attract more of the workers Australia needs and help reduce the risk of exploitation for those who live, work and study in the country, Ms O’Neil said.

Opposition migration spokesman Dan Tehan has said that the government was too slow to adjust migration policies designed to help Australia recover from the pandemic.

“The horse has bolted when it comes to migration and the government not only cannot catch it but cannot find it,” he said at the weekend.

The Labor government’s popularity has dwindled since its election last year, and in recent weeks it has been under pressure from some quarters to temporarily reduce migration to help ease Australia’s housing crisis.
