Labour Day falls on the first Monday of October in New South Wales, South Australia and the ACT, the only three jurisdictions observing the holiday on this date. October 2026 carries this public holiday in those three states, with every other state and territory working through an ordinary day without any Labour Day observance at all this month. Labour Day applies only in New South Wales, South Australia and the ACT during October, on the first Monday.
October opens the fourth calendar quarter of 2026, which runs from October to December, and the financial year's second quarter, which also runs from October to December under the financial-year calendar. Both quarter systems track the same three months in October 2026, aligning exactly for this stretch of the year unlike most other quarters. Daylight saving returns on the first Sunday of October in the five states and territories that observe it.
October 2026 closes with the spring racing carnival reaching its final build-up and the tax deadline just passed. November follows with the Melbourne Cup on the first Tuesday, Remembrance Day on 11 November, and the start of the tropical north's cyclone season, which runs from November through to the following April. The self-lodgement tax deadline falls on 31 October, at the very end of October.
