The spring racing carnival runs through October in the lead-up to the Melbourne Cup, held on the first Tuesday of November. October 2030 also carries the NRL and AFL grand finals, held earlier in the month, two of the biggest fixtures on the national sporting calendar, drawing crowds well beyond the two competing codes' home states. School Term 4 begins across every state during October, the final term of the school year.
The working-day count for October 2030 subtracts Labour Day only in New South Wales, South Australia and the ACT, where the holiday falls on the first Monday of the month. Every other state and territory counts the full run of weekdays across the 31 days of October without this particular subtraction applying. October opens the fourth calendar quarter of 2030 as well as the financial year's second quarter.
October 2030 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.
