According to ABS statistics, about 60 per cent of students in full-time tertiary education have jobs (this includes vocational and higher education). Their major occupations put them at elevated risk of catching infectious diseases and of losing hours or jobs due to the COVID-19 recession.

Because the census has detailed occupational information I am using it as my data source for jobs, even though it is now nearly four years old. The chart below shows the top 20 jobs for higher education students aged 30 or less who work part-time. The top 20 includes just over two-thirds of all employed students in this group.
As expected, student employment has a strong skew to occupations with large amounts of routine interaction with other people. Sales assistants are by far the largest single group. Waiters, bar attendants and baristas make up the next two largest groups. People in these occupations are all relatively likely to interact with someone with COVID-19, although if self-quarantine works not while that person is showing symptoms.
