The 2024–25 Australian region cyclone season is an ongoing weather event in the southern hemisphere. The season has officially started on 1 November 2024 and will end on 30 April 2025, however, a tropical cyclone could form at any time between 1 July 2024 and 30 June 2025 and would count towards the season total. During the season, tropical cyclones will be officially monitored by one of the three tropical cyclone warning centres (TCWCs) for the region which are operated by the Australian Bureau of Meteorology, National Weather Service of Papua New Guinea and the Indonesian Agency for Meteorology, Climatology and Geophysics. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services including Météo-France and the Fiji Meteorological Service will also monitor the basin during the season.
Ahead of the season officially starting on 1 November, the Australian Bureau of Meteorology (BoM) and New Zealand's National Institute of Water and Atmospheric Research (NIWA) both issued a tropical cyclone outlook that discussed the upcoming season.[2][3] These outlooks took into account a variety of factors such as a developing weak to moderate La Niña event and what had happened in previous seasons such as 1983–84, 1995–96, 2005–06 and 2017–18.[2][3] The Southwest Pacific tropical cyclone outlook issued by New Zealand's National Institute of Water and Atmospheric Research (NIWA) in conjunction with MetService, the BoM and various other Pacific meteorological services, predicted that six to ten tropical cyclones would occur over the South Pacific Ocean between 135°E and 120°W.[3] The outlook also predicted that three to four of these tropical cyclones would intensify further and become either a Category three, four or five severe tropical cyclone on the Australian tropical cyclone intensity scale.[3] In addition to contributing towards the Southwest Pacific tropical cyclone outlook, the BoM predicted that tropical cyclone activity within the whole region between 90°E – 160°E and each of its self defined subregions would be near normal.[2] They also warned that the likelihood of a severe tropical cyclone was higher than average because of the warmer than average ocean temperatures that had been forecast for the region.[2]

On 14 November, the Bureau of Meteorology noted that a tropical low could form west of Sumatra.[4] Several days later, they noted that the tropical low was developing.[5] Further consolidation due to a westerly wind burst, which also spawned a twin cyclone, prompted the Joint Typhoon Warning Center to first track it on 23 November.[6] Despite deep convection being displaced due to moderate to high wind shear, the system's circulation became increasingly defined, prompting the JTWC to issue a tropical cyclone formation alert on the disturbance.[7]

A tropical low formed off the southwestern coast of Java on 4 December. The storm caused floods and landslides in Sukabumi Regency, West Java, killing eight people and leaving seven others missing, with one home destroyed and 39 others damaged in the regency.[8] Flooding also killed three people in Lebak Regency, Banten.[9]
The Australian Bureau of Meteorology (TCWC Melbourne) monitors all tropical cyclones that form within the Australian region, including any within the areas of responsibility of TCWC Jakarta or TCWC Port Moresby.[10] Should a tropical low reach tropical cyclone strength within the BoM's area of responsibility, it will be assigned the next name from the following naming list. The names that will be used for the 2024–25 season are listed below:
TCWC Jakarta monitors Tropical Cyclones from the Equator to 11°S and from 90°E to 145°E. Should a Tropical Depression reach Tropical Cyclone strength within TCWC Jakarta's Area of Responsibility then it will be assigned the next name from the following list.[10]

TCWC Port Moresby
Tropical cyclones that develop north of 11°S between 151°E and 160°E are assigned names by the Tropical Cyclone Warning Centre in Port Moresby, Papua New Guinea. Tropical cyclone formation in this area is rare, with no cyclones being named in it since 2007.[11] As names are assigned in a random order, the whole list is shown below:
