The Electronic Travel Administration of Australia (ETA) is a kind of visa method, which was first introduced by the Australian Immigration Bureau in 1996. It is an online application system developed to facilitate foreigners to issue electronic visas, and the tracking system for boarding Australian flights was originally designed to improve the visa examination efficiency of tourists/business people entering Australia. In the future, countries including the United States and Sri Lanka will also adopt e-visa as visa-free treatment for foreign tourists/business people.
