Australian Transit Visa
There are a number of visa options for people transiting through Australia for 72 hours or less, including Transit without visa arrangements and Transit visa (subclass 771).
If you intend to stopover in Australia longer than 72 hours, you will not be eligible for a transit visa and should obtain another type of visa.
Note: You must apply for a Transit visa (subclass 771) outside Australia. You must also be outside Australia when the visa is granted.
Electronic Travel Authority
The ETA or Electronic Travel Authority program was designed by the Australian Government to allow tourists from countries like Singapore and over 30 other countries listed below fast access to online visa processing via the internet.
The program is so successful that up to 9 million people a year apply for and receive ETA Visas. Not everyone is approved on the first try and approximately 8% of first try applications are declined for various reasons.
