A tourist visa allows people to visit Australia for tourism, family or friend visits, or short-term study for up to three, six, or twelve months. The requirements include a valid passport, good character, enough funds to support themselves, and a genuine reason for visiting. Proof of travel plans and accommodations may also be required. The online application and fee must be submitted, and processing times can vary. Remember, the visa does not permit working or studying in Australia, and overstaying the visa has serious consequences, including deportation and future entry ban.
