If you are suffering from any disease or undergoing any treatment at the time of travelling, you need to obtain your doctor’s prescription that it is totally safe for you to travel at that particular time. Otherwise, you will not be allowed to travel to Australia with such underlying medical conditions.
You should book your return ticket before the expiration of your Australian Visa. Otherwise you will have to pay fine or you have to extend your stay by spending some more money there. It is always safe to book your ticket before travelling so that you do not face any difficulty at the time of departure from the country.
You should have all the important documents with you at the time of travelling. These documents includes your original Passport, bank statements, passport sized photographs, your work permit to work in Australia etc. along with some other important documents.
