If you have a pre-existing medical condition, it is recommended that you see your doctor as soon as possible and obtain an English medical certificate or an English certificate for any medication you are taking. In addition, you need to declare the condition on the Health Declaration Form, which is a necessary document for the ANU travel. If necessary, the School Doctor may request an interview before your departure, in which case you should follow the instructions.
Having a medical certificate or other documentation in English can be used to prove your medical needs at the baggage inspection on entry to Australia and can also help you to obtain medical treatment while in Australia.
