How to apply for an Australian visas / Australia ETA
The Australian government is making the Australia visa process one of the easiest and most flexible for travelers. Authorization to enter Australia is normally valid for one year, thus making trip planning easier for travelers who wish to visit Australia. The authorization to enter Australia is issued under two categories, either Electronic Travel Authorization (ETA) or eVisitor. Both types of visas are effectively the same, although selection to apply for the appropriate category depends on the nationality of the applicant.
Visa applications can be done completely online. Travelers are not required to visit the Australian embassy nor send in their passports. Once online visa applications are approved, applicants will receive their visa by email, which is recognized by all airlines traveling inbound to Australia and provided that all your travel documents are in order, you should have no trouble boarding your flight to Australia.
