To visit Australia as a tourist, most international visitors need to apply for a subclass 600 visitor visa. Requirements include a valid passport, completed application form, recent photograph, proof of sufficient funds, and evidence of the purpose of visit. Some nationalities may be eligible for the Electronic Travel Authority (ETA) or eVisitor visa, which are simpler to obtain. All visitors must meet health and character requirements. Processing times vary, but it's recommended to apply at least a month before intended travel.
