If you've received an Australian visitor visa, you may have noticed a condition listed on your grant letter: Condition 8558. For many visitors, this three-sentence condition is one of the most important — and most misunderstood — parts of their visa.
Let's break it down in plain English.
What Does Condition 8558 Actually Say?
Condition 8558 limits how long you can stay in Australia within any given 18-month rolling period. The full text from the Department of Home Affairs reads:
You must not remain in Australia for more than 12 months in any period of 18 months.
That's it. But the implications are significant, especially if you make multiple trips or plan to stay long-term.
Breaking Down the Rule
The 18-Month Rolling Period
The key word here is rolling. This isn't a fixed calendar year — the 18-month window moves forward continuously from any given date.
Here's a simple example:
| Trip | Entry | Exit | Days in Australia |
|---|---|---|---|
| Trip 1 | 1 Jan 2024 | 30 Jun 2024 | 182 |
| Trip 2 | 1 Sep 2024 | 31 Jan 2025 | 153 |
| Total | 335 |
In the 18-month window from 1 Jan 2024 to 30 Jun 2025, this visitor has spent 335 days — well under the 365-day limit. They're compliant.
Add another 2-month stay from February 2025 and the total reaches 395 days — a breach of 30 days.
What Counts as a "Day in Australia"?
The Department of Home Affairs counts calendar days, not nights. Both the day you arrive and the day you depart are counted as days spent in Australia.
Which Visas Have Condition 8558?
Condition 8558 typically appears on:
- Subclass 600 — Visitor visa (Tourist stream)
- Subclass 601 — Electronic Travel Authority (ETA)
- Subclass 651 — eVisitor
Not every holder of these visas will have this condition applied. Always check your Visa Grant Notice — it will explicitly list any conditions attached to your visa.
You can verify your visa conditions through the official VEVO (Visa Entitlement Verification Online) tool on the Department of Home Affairs website.
What Happens If You Breach Condition 8558?
Breaching a visa condition is a serious matter under the Migration Act 1958. Possible consequences include:
- Visa cancellation — under s.116 of the Migration Act, the Department may cancel your visa
- Impact on future applications — a history of condition breaches can affect character assessments
- Restricted re-entry — in serious cases, a travel ban or exclusion period may apply
The vast majority of breaches are unintentional — visitors simply lose track of their cumulative days across multiple trips.
Common Misconceptions
"I left and came back — does the clock reset?"
❌ No. The 18-month window is a rolling lookback from any given date. Departing Australia does not reset your previous days spent inside the country during the window.
"My visa says '12 months, multiple entry' — can I stay 12 months each visit?"
❌ No. "12 months multiple entry" describes how long your visa is valid and that you may enter more than once. Condition 8558 separately caps your total time in Australia at 12 months within any rolling 18-month period, regardless of how many entries you make.
"Transit days don't count, right?"
✅ Correct — provided you remain airside and do not clear Australian Border Force. If you pass through immigration for any reason, those days are counted.
