The 12/18 Month Rule
Here's how Australia counts your days
Rolling 18-Month Window
Australia looks at any 18-month period, not fixed calendar years. The window moves forward with each new day.
365-Day Maximum
Within that 18-month window, you can spend a maximum of 365 days (12 months) in Australia.
Days Fall Off
As time passes, your oldest days drop out of the window, freeing up days for future visits.
