Condition 8558 Stay Calculator
For travellers on multiple-entry visitor visas subject to condition 8558: enter the dates of each arrival in and departure from Australia to estimate the days counted within any rolling 18-month window, your margin against the 365-day ceiling, and a risk level. Both the arrival day and the departure day are counted; results are an initial estimate only.
Condition 8558 requires that the visa holder must not stay in Australia for more than 12 months in any 18-month period. With repeated entries and exits the window keeps rolling, which is easy to miscount by hand — this tool applies the same counting rules our consultants use.

One row per stay: the date you entered Australia and the date you left. If you are currently in Australia, leave the departure date of the last row blank and today’s date is used as the estimate.
Counting includes both the arrival day and the departure day. Results are an initial estimate only — verify against VEVO, your grant letter and professional advice.

The table shows each stay’s days counted in the current 18-month window, and the rolling total at each departure.
Disclaimer: this tool performs a mechanical estimate based on the information you enter. It is not migration or legal advice, and it does not replace Department of Home Affairs records, VEVO results, your visa grant letter, or formal advice from a registered migration agent. The counting basis (12 months estimated as 365 days) reflects the rules as at the build date — always defer to the Department’s current rules.
What Is Condition 8558?
8558 is a common condition on Australian visas, most often seen on multiple-entry visitor visas (including some subclass 600 visitor visas frequently used for long-stay parent visits). Whether it applies to your visa is determined by your grant letter and VEVO record.
What the condition requires
You must not stay in Australia for more than 12 months in any 18-month period. The window rolls — it is not a calendar year, and it is not fixed from your first arrival.
How days are counted
Counting is inclusive: both the arrival day and the departure day count as days in Australia. 12 months is estimated as 365 days; the check window is the rolling period starting 18 months before the check date plus one day.
Common misconception
Condition 8558 does not "reset every 18 months". The window rolls with time and no 18-month period may exceed the ceiling; a short trip out of Australia does not reset your used days.
Condition 8558 Counting FAQs
Which visas carry condition 8558?
Most often multiple-entry visitor visas — including some subclass 600 visitor visas, such as the 3-year and 5-year multiple-entry arrangements commonly used for parent visits. Check your grant letter, or confirm through VEVO.
Do the arrival day and departure day count as days in Australia?
Yes, both. This tool uses the same basis as our consultants’ worksheet: the arrival day and the departure day are both counted.
When does the 18-month window start?
The window is not fixed — it rolls with the check date: it runs from 18 months before the check date (usually a departure date, or today if you are currently in Australia) plus one day, up to the check date. No such window may exceed the ceiling.
Can I rely on the result as formal evidence?
No. The result is an initial estimate for planning only. For a formal position, rely on Department of Home Affairs records, VEVO results and your grant letter, or consult a registered migration agent.
What if the tool shows I am over the 365-day ceiling?
We recommend reviewing your actual movement records with a registered migration agent as soon as possible. Visa conditions and travel histories differ from person to person, and a tool cannot replace professional assessment of your individual case.
