1. What Is Condition 8558?

Condition 8558 is a visa condition attached to Australian Visitor Visa subclass 600, which states that the visa holder must not stay in Australia for more than 12 months in any 18-month period. This calculator helps determine compliance with this condition.

2. How The Calculator Works

The calculator uses the following logic:

Where:

• \( stay\_durations \) — Each individual stay duration in Australia (in days)
• \( rolling\_period \) — 18 months (default, can be adjusted)
• 365 days — Maximum allowed stay in the rolling period

Explanation: The calculator checks all possible 18-month windows to find if any window contains more than 365 days of stay.

3. Importance Of Compliance

Details: Compliance with condition 8558 is crucial for maintaining visa validity. Non-compliance may result in visa cancellation, future visa refusals, or re-entry bans.

4. Using The Calculator

Tips: Enter each stay duration in days, one per line. The calculator will check all possible rolling periods to determine if any 18-month period contains more than 365 days of stay.

5. Frequently Asked Questions (FAQ)

Q1: What counts as a "stay duration"?
A: Any continuous period spent in Australia counts as a single stay duration, from entry date to exit date.

Q2: How is the 18-month period calculated?
A: It's a rolling window - any consecutive 18-month period in your travel history must not exceed 365 days of stay.

Q3: Does time outside Australia reset the clock?
A: No, the 18-month period keeps rolling. Time outside Australia doesn't reset the count, it just means those days aren't counted as stay days.

Q4: What if I have multiple entries/exits?
A: Enter each stay duration separately. The calculator will check all combinations.

Q5: Can I use this for other visa types?
A: This calculator is specifically for Visitor Visa subclass 600 with condition 8558. Other visas may have different conditions.
