Australian ETA Tourist Visa

Description:
The Electronic Travel Authority for Australian Tourist Visas is the most advanced and streamlined visa authorisation system in the world. The ETA replaces visa labels or stamps and removes the need for application forms. The Australian ETA is an electronically stored authorisation for travel to Australia, meaning you don't need paper documentation or a stamp in your passport.

An ETA Tourist Visa allows you to stay in Australia for up to 3 months on each arrival within 12 months from the date the visa was granted.

The ETA differs from traditional visas in that there are no application forms to fill in and no visa label or stamp in the passport.
The ETA is available to passport holders from Australian Government specified countries and regions. To apply for an ETA (Visitor), you must be outside Australia and hold a passport issued by an ETA-eligible country or region (see below for the full list).
You must apply for your ETA with the passport and passport number you will be travelling to Australia with; the visa is linked to this number. If your passport is lost/stolen or replaced before you travel to Australia, you will be required to re-apply for an ETA visa.
