Is an electronic travel authorization system that permits holders to travel to the United States of America without a visa.
The US ESTA is available to Australian nationals if their visit to the States meets certain criteria.
The purpose of the visit must be for one of the following:
Citizens of Australia may use the ESTA to enter the USA for stays of up to 90 days at a time.
Once registered, the ESTA is valid for 2 years or until the individual’s passport expires, whichever comes first. If your passport will expire in less than two years, you will receive an ESTA valid until the passport’s expiration date.
The holder of an approved ESTA can then use it to enter the United States on multiple occasions within this period. There is no set requirement for how long you must wait between your visits to the U.S., but you must have a reasonable amount of time between your visits. You need to show that Australia remains your country of residence and you intend to return there after your short trip to the U.S.
Australian visitors must register their details with the system prior to embarking on the journey to the USA. We recommended applying as soon as you finalize your travel plans to the US. However, you can still request an ESTA up to 72 hours before your departure.
