What is an ETA?
An ETA is equivalent to a visa, but there is no stamp or label in your passport and there is no need for you to visit an Australian diplomatic office to submit an application. Applications for ETAs can be submitted through travel agents or airlines.
When you arrive at an airport for check-in on a flight to Australia, the airline check-in staff can electronically confirm that you have authority to board the flight to Australia.
