About the calculator

What is the Visa Stay Calculator?

A free planning tool that estimates your permitted stay under Australian visa condition 8558 from the entry and exit dates you enter. It counts days in the rolling 18-month window, shows days remaining, and estimates the latest safe exit date for a current or planned trip.

How accurate is the 8558 calculator?

It applies the standard wording of condition 8558 exactly, but it cannot see your visa record. Conditions vary and can change. Always confirm your conditions in your grant notice or on VEVO.

Can I rely on this for visa compliance?

No. It is informational only and not legal advice. Verify your visa status and conditions with official sources or a registered migration agent before making travel decisions.

I got an error. What should I do?

Check that your dates are valid, that exit dates are on or after entry dates, and that trips do not overlap. If it still fails, contact us with a short description of the issue and the browser you are using.

Condition 8558

What does “12 months in 18 months” mean?

A rolling limit: the total time you spend in Australia must not exceed 12 months (365 days) within any 18-month period, measured backwards from any date. Read the full condition 8558 guide.

Does leaving Australia reset condition 8558?

No. Earlier stays still count while they fall inside the last 18 months. A trip only stops counting once it is more than 18 months in the past.

Do arrival and departure days count?

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

Where can I confirm my visa details and condition 8558 wording?

In your visa grant notice and on VEVO (Visa Entitlement Verification Online). Our guide shows how to check your conditions on VEVO.

Can I extend my stay if I have condition 8558?

Condition 8558 is a limitation, not a visa length. Staying longer generally means applying for a new visa. See can you extend a visitor visa 600?

Your data

Does the calculator store my personal information?

The dates you enter are processed in your browser and saved only in your browser’s local storage so they are still there when you come back. They are never sent to our servers. See the Privacy Policy.

Do I need an account?

No. Everything on visainfo.cc is free and works without signing up.

Still need help?

If your case is complex or you’re unsure what your condition wording means, check VEVO and consider speaking with a registered migration agent.
