Australia on Monday said it would tighten visa rules for international students and low-skilled workers that could halve its migrant intake over the next two years as the government looks to overhaul what it said was a "broken" migration system.

The decision comes after net immigration was expected to have peaked at a record 510,000 in 2022-23. Official data showed it was forecast to fall to about a quarter of a million in 2024-25 and 2025-26, roughly in line with pre-COVID levels.

"Our strategy will bring migration numbers back to normal," Home Affairs Minister Clare O'Neil said during a media briefing.
