All visitors to Australia need a valid passport and an Australian visa or Electronic Travel Authority (ETA).
Visa types depend on length of stay and the visit’s purpose. Lodge online applications for ETAs or acquire forms from more than 300,000 travel agents, 75 airlines and Australian diplomatic offices worldwide. If you do not hold a passport approved for ETA, get a ‘label’ visa from Australian embassies, high commission offices or consulates. The Immigration Department’s website offers an Event Coordinators' Network to help event managers. View Australia’s immigration website. https://www.homeaffairs.gov.au/
