2030 has 365 days, and January opens the year with the tropical north deep in its wet season, part of the cyclone season that runs from November through to April. In the southern states, 16 January 2030 sits in the driest, hottest stretch of the year, when bushfire warnings are issued most frequently across Victoria, South Australia, Tasmania and inland New South Wales.
The Ekka public holiday in greater Brisbane is held on a Wednesday during the Royal Queensland Show each August, one of the few recurring public holidays fixed to this day of the week. Wednesday 16 January 2030 falls on the same weekday as this regional observance, which applies only within greater Brisbane and not to the rest of Queensland.
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.
