Electronic Travel Authority
The ETA System was developed to streamline and simplify visa application procedures for the rapidly increasing numbers of tourists and short-term business visitors traveling to Australia .The ETA System allows a travel agent or an airline to obtain an Eat on behalf of a traveler. This removes the need for the traveler to visit an Australian Embassy to obtain a visa label in their passport . A traveler may also apply for an EAT using the Internet.
At check-in ,the Eat System allows an airline clerk to determine if an inbound visitor has authority to travel to Australia-either as an ETA or a traditional visa .
