Autumn begins on 1 March, and by 19 March 2030 the southern states see shorter days and cooler mornings settling in.

The Melbourne Cup is held on the first Tuesday of November every year, a public holiday in metropolitan Melbourne.

The quarter containing 19 March 2030 is based on the calendar year running January to December, a separate system from the Australian financial year, which runs from 1 July to 30 June and splits into its own four quarters. Businesses often track both systems side by side, one for tax filings and one for calendar-year planning.
