The Electronic Travel Authority (ETA) (subclass 601) lets you enter Australia as many times as you want for up to 12 months if you are:
- a tourist
- travelling for business purposes
You can stay in Australia for up to three months on each visit.
The ETA is an electronically stored authority for travel to Australia. You must be outside Australia when you apply and when the ETA is granted.
An ETA is linked electronically to your passport. It can be seen by staff at airlines, travel agencies and Australian border agencies.
