OSHC is the health insurance international students are generally required to hold as a condition of the student visa. It is bought from a government-approved provider, and you usually need it in place before your visa is granted.
It is not the same as Medicare, the public scheme that residents use, and it is not the same as a comprehensive private policy at home. Knowing the difference before you need a doctor saves a lot of stress.
Standard OSHC is medical cover, not everything-cover. These are commonly excluded or only covered under a higher-tier policy:
Australia has Reciprocal Health Care Agreements with a number of countries, and students from a few of those countries may be exempt from the usual OSHC requirement or treated differently under it.
This depends entirely on your nationality and your circumstances, so check the official page rather than assuming it applies to you.
For anything routine, you book a GP appointment. Some clinics bill your insurer directly; at others you pay and claim the money back afterwards, so keep receipts.
For a genuine emergency you call 000 and go to a hospital emergency department — you do not need to sort out insurance first.
