All visitors to Australia require a passport valid for the duration of their stay. Members of the EU and US nationals are eligible for a special electronic visa called an ETA valid for a stay of up to 3 months. These ETAs are machine readable and invisible to the human eye, they can be obtained from airlines, travel agents or in some cases online at www.eta.immi.gov.au. Visitors countries not eligible for ETAs or those wishing to stay longer than 3 months will have to apply for an ordinary visa which is available from your local Australian High Commision.
