List of off-season Australian region tropical cyclones

An off-season Australian tropical cyclone is a tropical cyclone that existed in the Australian Region, between 90°E and 160°E, outside of the official season. The World Meteorological Organization currently defines the season as occurring between 1 November and 30 April, of the following year, which is when the majority of all tropical cyclones exist. During the off-season, systems are more likely to either develop during or persist until May, with approximately 52% of such storms occurring during that month. Occasionally, however, storms develop in October, with approximately 34% of such storms occurring during that month. As of 2022, there have been 94 tropical cyclones known to have occurred off-season.

Off-season cyclones are most likely to occur in the Coral Sea, with most affecting land in some way. Cumulatively, at least 4 deaths occurred due to the storms, the most recent off-season storm was Tropical Low 93S in September 2025.

Systems

The wind speeds listed are maximum ten-minute average sustained winds, while the pressure is the minimum barometric pressure, both of which are estimates taken from the archives of either Météo-France, the Australian Bureau of Meteorology, the Fiji Meteorological Service, and New Zealand's MetService. If there are no known estimates of either the winds or pressure then the system is listed as "Not specified" under winds or pressure, if there is no known estimated winds or pressure. For deaths and damages "None" indicates that there were no reports of fatalities, although such storms may have impacted land. The damage totals are the United States dollar of the year of the storm.
