List of Category 1 Australian region tropical cyclones

Category 1 is the lowest classification on the Australian tropical cyclone intensity scale used to classify tropical cyclones, that have 10-minute sustained winds of 33–47 kn. tropical cyclones have peaked as Category 1 tropical cyclones in the South Pacific tropical cyclone basin, which is denoted as the waters surrounding Australia to the south of the equator, between 90°E and 160°E. The earliest tropical cyclone to be classified as a Category 1 tropical cyclone was Carmen. The latest was Ellie which was classified as a Category 1 tropical cyclone as it affected Australia.

Background
The Australian region tropical cyclone basin is located to the south of the Equator between 90°E and 160°E. The basin is officially monitored by the Australian Bureau of Meteorology, Papua New Guinea's National Weather Service as well as Indonesia's Badan Meteorologi Klimatologi dan Geofisika. Other meteorological services such as the Fiji Meteorological Service, the New Zealand MetService, Météo-France as well as the United States Joint Typhoon Warning Center also monitor the basin. Within the basin a Category 1 tropical cyclone is a tropical cyclone that has 10-minute mean maximum sustained wind speeds of 33–47 kn on the Australian tropical cyclone intensity scale. A named storm could also be classified as a Category 1 tropical cyclone if it is estimated, to have 1-minute mean maximum sustained wind speeds of between 64–82 kn on the Saffir–Simpson hurricane wind scale. However, this scale is not officially used in the Australian, however, various agencies including NASA also use it to compare tropical cyclones. A Category 1 tropical cyclone is expected to cause some damage, if it significantly impacts land at or near its peak intensity.

 * Tropical Cyclones Isobel (2006), Odette (2008), Fletcher (2014) were declassified as tropical cyclones during post-season analysis, after the BoM determined that the system had not reached tropical cyclone intensity.


 * Tropical Cyclone's Ken (2004) Gabrielle (2009), Anggrek (2010) were declassified as tropical cyclones during post-season analysis, after the BoM estimated that gale force winds did not extend more than 1/2 way around the centre.


 * Tropical Cyclone Peta was declassified as a Category 1 tropical cyclone during post-season analysis, after the BoM estimated that gale force winds did not extend more than 1/2 way around the centre for more than 6 hours.
