It began on 1 November 2011, and ended on 14 May 2012. The regional tropical cyclone operational plan defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on 1 July 2011 and ended on 30 June 2012. The scope of the Australian region is limited to all areas south of the equator, east of 90°E and west of 160°E. This area includes Australia, Papua New Guinea, western parts of the Solomon Islands, East Timor and southern parts of Indonesia. Tropical cyclones in this area are monitored by five Tropical Cyclone Warning Centres (TCWCs): the Bureau of Meteorology in Perth, Darwin and Brisbane; TCWC Jakarta in Indonesia; and TCWC Port Moresby in Papua New Guinea. The Joint Typhoon Warning Center issues unofficial warnings for the region, designating tropical depressions with the "S" suffix when they form west of 135°E, and the "P" suffix when they form east of 135°E. __TOC__ Seasonal forecasts TSR forecastsDate Tropicalstorms Severe Tropicalcyclones Landfallingcyclones ACE Ref Average (1975/76–2010/11) 10.5 5.5 4.5 79 11 May 2011 Lea, Adam Extended Range Forecast for Australian-Region Tropical Storm Activity in 2011/12 Tropical Storm Risk Consortium http://www.tropicalstormrisk.com/docs/TSRAUSForecastMay2011.pdf 11 May 2011 Saunders, Mark7 December 2011 Lea, Adam December Forecast Update for Australian-Region Tropical Storm Activity in 2011/12 Tropical Storm Risk Consortium http://www.tropicalstormrisk.com/docs/TSRAUSForecastDec2011.pdf 7 December 2011 Saunders, Mark 11 May 2011 11.2 5.9 4.7 – 4 July 2011 10.6 5.5 4.4 – 4 July 2011 Lea, Adam July Forecast Update for Australian-Region Tropical Storm Activity in 2011/12 Tropical Storm Risk Consortium http://www.tropicalstormrisk.com/docs/TSRAUSForecastJul2011.pdf 4 July 2011 Saunders, Mark 8 September 2011 11.8 6.2 4.9 – 8 September 2011 Lea, Adam September Forecast Update for Australian-Region Tropical Storm Activity in 2011/12 Tropical Storm Risk Consortium http://www.tropicalstormrisk.com/docs/TSRAUSForecastSep2011.pdf 8 September 2011 Saunders, Mark 8 November 2011 12.9 6.8 5.3 – 8 November 2011 Lea, Adam November Forecast Update for Australian-Region Tropical Storm Activity in 2011/12 Tropical Storm Risk Consortium http://www.tropicalstormrisk.com/docs/TSRAUSForecastNov2011.pdf 8 November 2011 Saunders, Mark 7 December 2011 12.9 6.8 5.3 94 Region Average Chance ofAbove average Actual activity Ref Whole 12 80% 7 Western 7 65% 5 North-Western 5 60% 3 Northern 3 60% 1 Eastern 4 65% 1 Total ForecastCenter Tropicallows Tropicalcyclones Severe tropicalcyclones Ref Actual activity: BoM 20 7 3 Actual activity: JTWC 17 8 4 During each tropical cyclone year, Australia's Bureau of Meteorology National Climate Centre (BoM), the Guy Carpenter Asia-Pacific Climate Impact Centre, New Zealand's National Institute of Water and Atmospheric Research (NIWA) and partners issue seasonal forecasts for the Australian region and its various subregions. Since a tropical cyclone can move through a region, the actual number of tropical cyclones in a region include any that form in or move into a region from another. Bureau of Meteorology In October 2011, ahead of the tropical cyclone season starting on 1 November, the BoM issued seasonal forecasts for the whole Australian region, one for each of the subregions Western, North-Western, Northern and Eastern Australia with each one covering the whole tropical cyclone year.2011–2012 Australian Tropical Cyclone Season Outlook Australian Bureau of Meteorology http://www.bom.gov.au/climate/ahead/tc.2011-12.shtml 8 January 2013 National Climate Centre https://web.archive.org/web/20130122001439/http://www.bom.gov.au/climate/ahead/tc.2011-12.shtml 22 January 2013 15 October 2012 dead For each forecast they took into account, the current neutral ENSO conditions to weak La Niña conditions that had been observed during that summer. For the whole region they predicted that there was an 80% chance that the season would be above average. For the Western region between 90°E and 125°E, the BoM forecast that the area would see activity near to or slightly above the average, with a 35% chance of a below average cyclone activity. For the North-Western subregion between 105°E and 130°E, it was predicted that there was a 60% chance of above average tropical cyclone activity, while TCWC Perth noted that there was a likelihood of two tropical cyclones and one severe tropical cyclone impacting Western Australia.Australian Bureau of Meteorology Western Australia Regional Office Communities in WA's north-west urged to prepare now http://www.bom.gov.au/announcements/media_releases/wa/20111017.shtml 8 January 2013 https://web.archive.org/web/20120903060527/http://www.bom.gov.au/announcements/media_releases/wa/20111017.shtml 3 September 2012 17 October 2011 live The Northern Territory which was defined as being between as being 125°E and 142.5°E had a 60% chance of being above average, while the Eastern region had a 65% chance of having an above average tropical cyclone season.

On 20 December, as convection had consolidated over the systems low level circulation centre, the JTWC issued a Tropical Cyclone Formation Alert on the system.

As a result of this, the JTWC decided to cancel their Tropical Cyclone Formation Alert late on 22 December, while TCWC Brisbane reported that Fina had degenerated into an extratropical cyclone. Over the next few days Cyclone Fina developed storm force winds and produced dangerous surfing conditions in southeast Queensland over the Christmas holiday. In post-analysis in early 2012, the BoM downgraded Fina to a tropical low.https://www.bom.gov.au/cyclone/history/Fina.shtml 17 June 2025 live Tropical Cyclone Fina Bureau of Meteorology Brisbane Tropical Cyclone Warning Center 17 June 2025 https://web.archive.org/web/20250617234925/https://www.bom.gov.au/cyclone/history/Fina.shtml Tropical Low 03U (Benilde) Aus low depression 21 December 28 December (Exited basin) 30 1000 03-U Dec 23 2011 0335Z.jpg Benilde 2011 path.png On 21 December, TCWC Perth reported within their tropical weather outlooks that a tropical low was developing about 770 km (410 mi) to the northeast of the West Island of the Cocos (Keeling) Islands.

Late on 17 March, 17U began to stall in the southeastern Gulf of Carpentaria. Late on 18 March, TWCW Brisbane issued their last advisory on the storm, as it was not expected to become a tropical cyclone, at this point. However, the agency continued to track the storm on their outlook, until the storm's dissipation. Late on 19 March, Tropical Low 17U began moving southward, deeper into Queensland. Early on 20 March, wind shear began weakening the storm, as it turned eastward. Late on 21 March, 17U began emerging off the eastern coast of Queensland, as it was drawn towards a powerful extratropical cyclone, to the east. By 22 March, the extratropical storm had absorbed Tropical Low 17U, and thus the storm was dropped from TCWC Brisbane's outlook.

Late on 7 May, vertical wind shear from the north caused the system's northern convection to dissipate, as the storm turned to the southeast, prompting the JTWC to issue their last advisory on the system. However, on 8 May, the wind shear weakened, and the system regained its convection, as it began to reorganize. Later on the same day, 19S turned to the south-southwest and narrowly passed in between a few Indonesia islands. On 10 May, 19S turned to the southwest, as it approached Timor.
