Some countries regard the ETA as being equivalent to visa-free travel when deciding whether to grant the same to Australians wishing to enter their territory. The United States, for example, offers their Visa Waiver Program to Australian passport-holders, and one of the conditions for joining this scheme is that "Governments provide reciprocal visa-free travel for U.S. citizens for 90 days for tourism or business purposes". However, the United States has required from January 2009 a similar ETA, called the Electronic System for Travel Authorization, from citizens of Australia. As of December 1998, Japan has also granted visa-free access to Australians. Other ETA eligible countries and territories Canada, Hong Kong, Malaysia, Singapore and South Korea (90 days) and Taiwan (30 days) also grant visa-free access to Australians while Brunei grants Australians a 30-day visa on arrival.
