Introduction

Imagine you planned the perfect Australian adventure.
You have already pictured yourself walking along Sydney Harbour, exploring Melbourne, driving along the coast, or spending a few months experiencing life on the other side of the world.

Then reality interrupts your plans with one important question:
How long can a U.S. citizen actually stay in Australia?

The answer depends on the type of Australian visa or travel authority you hold.

For many American visitors, an Electronic Travel Authority (ETA) can allow stays of up to three months at a time, while Australia’s Visitor visa can allow a longer stay, potentially up to 12 months, depending on the visa granted and the circumstances of the applicant.

But there is one thing Americans should understand before booking their flight which is that:
Australia is not simply a “show up with your U.S. passport and enter” destination.

You generally need permission to travel to Australia before you arrive.
