Cyclone activity across northern Australia continues through February, part of a season that runs from November to April, while bushfire risk in the south stays at its summer peak. 17 February 2027 sits inside both seasonal windows, two months before daylight saving ends in the south-eastern states and autumn officially begins across the country on 1 March.
A public holiday landing on a Wednesday sits in the middle of its working week rather than beside a weekend, so it does not create a long weekend on its own. Wednesday 17 February 2027 falls on this day of the week, at the working week's midpoint, three working days deep into the week.
The working-day count on this page excludes both weekend days and any public holiday declared for the state selected, so the same date in 2027 can show a different total depending on which state's calendar applies to 17 February. Interstate businesses need to check more than one state's list before setting a national deadline.
