Damn right, it's big business for Australia; International education earned Australia $55 billion in 2025 from some ~ 844,000 students that year.

( ~ 850K students has been peak international student population per annum in Australia, its never exceeded a million )

These are temporary education visa's that may in a few cases lead to insecure work visa's in Australia and while some international students may get citizenship after 10 years of expensive and insecure stay in Australia .. the total number of permanent migrants accepted each year is (currently) capped at a modest 185,000 per annum (across the board, not just limited to former international students).
