STAR will only display units you are enrolled in with scheduled on-campus activities for the current study period. Cloud (online) units are not usually scheduled in STAR.
Check that you are enrolled in the unit for the current study period and that the unit is a campus-based unit (it will be a D mode or E mode). If you have only recently enrolled in the unit, then be aware that changes to enrolment can take up to 1 hour to appear in STAR.
For Cloud (online) units, you can find any scheduled events on your relevant online unit site through CloudDeakin.
For the latest information on COVID-19 and how it will affect your timetable, please visit the STAR website.
