Spring begins on 1 September across Australia. September 2030 brings warmer days back to the southern states after the winter months, while the tropical north moves out of its dry season toward the wet season and cyclone risk that returns in November and runs through to the following April, closing the seasonal loop that began the previous wet season. Spring begins on 1 September, the first day of September.
September closes the financial year's first quarter, which runs from July to September, and sits in the third calendar quarter of 2030, which closes at the end of the same month. Both quarter systems reset together at the end of September 2030, one of the few points where the two calendars align on the very same date. Spring begins on 1 September, the first day of September.
September 2030 closes with the football finals concluded and daylight saving about to resume in the south-eastern states. October follows with Labour Day long weekends in three states, the spring racing carnival building, and the self-lodgement tax deadline approaching on 31 October, four months after the lodgement window opened. Father's Day falls on the first Sunday of September every year.
