About half of international students in Australia are private renters and more than half of them rely on paid work to pay the rent, but most of the casual jobs they depend on have been lost in the coronavirus pandemic. The results of our recent survey (conducted pre-COVID-19) of international students living in private rental accommodation suggest up to half of them may now be unable to pay their rent. Many also live in quite crowded conditions, so will struggle to self-isolate even if they don't lose their current housing.
