Visitor visa (subclass 600) and stay limits
The Visitor visa (subclass 600) allows a temporary stay in Australia for tourism, business visitor activities, or visiting family and friends. Your visa may be issued with conditions that limit:
- how long you can stay per visit (for example “3 months after each entry”)
- how long you can stay within a rolling period (for example “12 months in 18 months”)
- what activities you can do (for example no work)
- insurance or other requirements, depending on your grant
Why people use an 8558 calculator
To estimate departure deadlines, remaining days, and whether planned travel dates could breach condition 8558.
What you must verify yourself
The exact wording of your condition 8558 in VEVO or your grant notice. Calculators cannot see your visa record.
Condition 8558 explained in simple terms
Condition 8558 is a “maximum period of stay” condition. In practice it appears in two common patterns:
Limit per stay
Your visa may limit each visit, for example “must not remain in Australia for more than 3 months after entry”. This is the simplest case: use the calculator’s Max stay per entry mode.
Rolling period limit
Your visa may apply a rolling cap, for example “must not remain in Australia for more than 12 months in any 18 months”. This requires tracking multiple trips: use the 12 in 18 months mode.
Key point: leaving Australia does not reset a rolling window
If your condition 8558 uses a rolling window, earlier visits still count as long as they fall inside the last 18 months. The window keeps moving forward with the calendar.
What you need before using a condition 8558 calculator
- 1
Your visa condition wording
Check VEVO or your grant notice to confirm whether your limit is per stay or rolling (for example 12 months in 18 months).
- 2
Accurate travel dates
For rolling limits you need previous entry and exit dates, at least every stay within the last 18 months.
- 3
A plan for uncertainty
Treat calculator results as planning guidance. If your case is complex, consider professional advice.
- 4
Official verification
Use official sources for confirmation. The calculator helps, but does not replace VEVO or Home Affairs.
Scenarios people calculate
Scenario 1: “3 months per entry” (limit per stay)
You enter Australia on a certain date and your grant limits you to a maximum stay per visit. You want to estimate the latest safe departure date.
Scenario 2: multiple trips and a rolling window (12 months in 18 months)
You have visited Australia several times. You want to know how many days remain within the rolling window and whether a planned trip could breach condition 8558.
Scenario 3: you are unsure which rule applies
This is common. The correct first step is to check your exact condition wording in VEVO or your grant notice. If it mentions “in any 18 months”, use the rolling rule.
