With Australia already sliding into its worst recession in almost a century, education leaders expect the disappearance of international students to cost billions of dollars. Data on how many international students have left the country this year is not yet available, but anecdotal evidence on departures and data on new enrolments paints a worrying picture. New enrolments of international students, who generally make up about 20% of all university students in Australia, grew by an average of 10% over the past two years. But growth in the first six months of this year was negligible as Australia closed its borders in March to all foreigners because of the pandemic. The slowdown in foreign student enrolments mean Australian universities are facing a revenue hit of between A$3.1 billion and A$4.8 billion ($2.2-$3.5 billion) this year alone, Catriona Jackson, Chief Executive of Universities Australia, told Reuters. New enrolments from China fell 8% in the first half of the year, compared with a gain of 4% across 2019, according to government data.
