Daylight saving ends on the first Sunday of April in New South Wales, Victoria, South Australia, Tasmania and the ACT, putting the clocks back an hour. Queensland, Western Australia and the Northern Territory keep the same clock they have run all year, so April 2030 briefly brings the whole country back onto a single time standard. April opens the second calendar quarter of 2030 as well.
The working-day count for April 2030 subtracts ANZAC Day on 25 April along with any days Easter's Good Friday and Easter Monday fall on within the month. Where ANZAC Day lands on a weekend, several states shift a substitute public holiday to the following Monday, adding a further day to the count in those states only. The tropical north's cyclone season, which runs from November, comes to its close by the end of April.
The shift from April into May brings whale migration season into full swing along much of the coastline and cooler nights becoming the norm across the southern states. April 2030 hands over a month carrying two national observances to one with only a single state-based public holiday, in Queensland and the Northern Territory alone. Term 1 school holidays overlap with the Easter break across every state during April.
