Australia has the highest ratio of international students per head of population in the world by a large margin, with 812,000 international students enrolled in the nation's universities and vocational institutions in 2019. Accordingly, in 2019, international students represented on average 26.7% of the student bodies of Australian universities. International education therefore represents one of the country's largest exports and has a pronounced influence on the country's demographics, with a significant proportion of international students remaining in Australia after graduation on various skill and employment visas.
