Common Entry Types

Electronic Travel Authority (subclass 601)
As a U.S. citizen, you need an ETA (subclass 601) before you travel, even though entry otherwise feels visa-free. Apply through the Australian ETA app for an AUD 20 service fee; most are approved within 24 hours, though applying at least 4 weeks ahead is recommended. It allows multiple entries over 12 months, with stays of up to 3 months each visit.

Overstay Consequences

  • There is no grace period — you become an 'unlawful non-citizen' the moment your permitted stay expires, even by a single day.
  • The Department of Home Affairs can detain and remove unlawful non-citizens from Australia.
  • Leaving within 28 days of your visa expiring can help you avoid a 3-year re-entry exclusion period, but you were still unlawfully present during that window — the 28 days is not a grace period for the overstay itself.
  • An ETA (subclass 601) cannot be extended while you're in Australia, and an overstay record can affect your eligibility for a future ETA.

Renewal Path

  1. 1You can't extend an ETA-based stay from inside Australia — if you want to stay longer, you need to apply for and be granted a different visa before your permitted stay runs out.
  2. 2There is no in-country renewal path for ETA holders wanting more time on the same authorization.
  3. 3If your status has already lapsed, Home Affairs' Immigration Status Resolution Service can advise on next steps, including voluntary departure.

The Gotcha

There's a widely repeated myth of a '28-day grace period' for overstaying in Australia — there isn't one. You're classified as an unlawful non-citizen from day one of overstaying, with zero leeway. The 28-day window only affects whether you get hit with a 3-year re-entry ban when you eventually leave, not whether the overstay itself was legal.
