Spring begins on 1 September, and by 11 September 2027 warmer days return across the southern states after the winter months. The AFL finals series runs through September, ahead of the Grand Final that follows in late September or early October, drawing national attention as one of the biggest fixtures on the Australian sporting calendar.

A public holiday that falls on a Saturday sits inside the weekend rather than beside it, so it does not automatically create a substitute day off during the working week; whether one applies depends on the specific holiday and the state. Saturday 11 September 2027 falls on this day of the week, inside the weekend itself.

2027 has 365 days on the calendar. Leap years add a single extra day to February, giving those years 366 days instead of 365 and shifting the day-of-year number for every date from March onward by one compared with an ordinary year. This is the only irregularity in the length of the Australian calendar year.
