Electronic Travel Authority (ETA)

All travellers to Australia, other than Australian and New Zealand citizens, are legally required to hold a valid visa to travel to Australia.

Australia's Electronic Travel Authority (ETA) system is the world's most advanced and streamlined travel authorisation system.

An innovative enhancement to ETA arrangements allows a traveller to apply for an ETA over the internet.

The ETA is an electronically-stored authority for travel to Australia for a short-term tourist or business entry. It replaces the visa label or stamp in a passport and removes the need for application forms.

ETAs are issued within seconds of being requested through computer links between the department, travel agents, airlines and specialist service providers around the world.
