Autumn is fully established across the southern states by 23 April 2030, with cooler mornings standard and the first talk of the ski season in the Snowy Mountains and Victorian Alps beginning to circulate. The tropical north's cyclone season runs through April before ending for the year, handing the north over to its long dry season.
The Melbourne Cup is held on the first Tuesday of November every year, a public holiday in metropolitan Melbourne. Tuesday 23 April 2030 falls on this day of the week, the same weekday the race runs on every year regardless of the date it lands on, drawing national attention well beyond Victoria's own borders.
2030 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.
