Finding the optimal mix of international and domestic students in post-secondary education is crucial, as shown by recent enrolment caps in Australia and Canada. Both countries have proposed around 30-35% caps, aiming to balance financial needs, community acceptance, and societal support. Canada introduced a two-year cap starting January 2024, while Australia plans similar measures for 2025. These caps are often government-mandated, reflecting pressures like inflation, rising living costs, and housing shortages. However, the debate continues on the merits and design of such caps, with differing opinions on the right proportion of international students.
