What the calculator handles

Most people breach condition 8558 by accident, adding up trips in their head. These are the cases the tool works out for you.

  • Multiple trips

    Add every entry and exit. The calculator adds them up inclusively, counting both your arrival and departure days.

  • A true rolling window

    It checks every possible 18-month window, not just the last 18 months, so an old trip cannot hide a breach.

  • Open-ended stays

    Still in Australia? Leave the exit date blank and see the latest date you can leave without going over.

  • Planned trips

    Add a future trip before you book flights to see whether the dates would push you past the limit.

  • Per-entry limits too

    Some grants cap each visit instead: 3, 6 or 12 months per entry. Switch modes and the maths follows.

  • Breach detection

    If any window exceeds 365 days, it tells you which window, by how many days, and when days free up again.

How it works

Three steps to a clear answer

  1. 1

    Add your trips

    Enter every entry and exit date from the last 18 months, and any trip you are planning. Leave the exit empty if you are still in Australia.

  2. 2

    Pick the rule on your grant

    Most Visitor visa (subclass 600) grants with condition 8558 use the rolling 12-in-18-month rule; some are worded as a maximum per entry.

  3. 3

    Read your result

    See days used, days remaining, the latest safe exit date for your current trip, and whether any 18-month window is over the limit.

Understanding the rule

What Australian visa condition 8558 means

Managing your permitted stay under an Australian visitor visa can be confusing, especially when your grant includes visa condition 8558. This condition restricts how long you can remain in Australia during a single visit or across a rolling period. Our 8558 visa conditions calculator simplifies compliance by estimating departure deadlines and tracking accumulated days so you can plan with confidence.

Whether your grant limits each stay to three or six months, or imposes the commonly cited “12 months in any 18-month period” rolling window, the tool lets you enter your travel dates and instantly see how many days remain. It is particularly valuable for frequent travellers who hold a multiple-entry Visitor visa (subclass 600) and need to balance visits with family, business or leisure commitments.

How the stay calculator works

You provide your entry and exit dates and select the condition type that matches your visa grant. The calculator then works out your total days spent in Australia during the relevant window, shows how many days you have remaining, and suggests the latest safe departure date for your current or planned trip. Results are displayed in real time, so you can adjust dates and see the impact immediately.

The tool is for planning purposes only. Your exact visa conditions may differ, and you should always verify them through VEVO or your visa grant notice. For a deeper explanation, read our condition 8558 guide.

Why track your visa stay online?

Overstaying your permitted period, even by a single day, can lead to visa cancellation, refusal of future applications and potential exclusion from re-entering Australia. A browser-based calculator removes the guesswork and gives you a clear record of your travel history. Unlike a manual spreadsheet, it handles overlapping windows, leap years and the precise date arithmetic that rolling-window conditions require.

See all FAQs
What is visa condition 8558?

Condition 8558 is a stay limitation attached to many Australian visitor visas, including the Visitor visa (subclass 600). In most grants it means you must not remain in Australia for more than 12 months in any 18-month period.

Does leaving Australia reset the 18-month period?

No. The window is rolling. From any given date the Department looks back 18 months and counts your total days in Australia. Earlier trips keep counting until they fall more than 18 months in the past.

Do arrival and departure days count?

Treat both as days in Australia. Our calculator counts them inclusively, which is the safer assumption when you are close to the limit.

Is this calculator official?

No. It is a free planning tool built from the publicly available wording of condition 8558. Always confirm your conditions in VEVO or with the Department of Home Affairs.
