2005–06 Australian region cyclone season
cyclone season in the Australian region
The 2005–06 Australian region cyclone season was an above average tropical cyclone season. It began on 1 November 2005 and ended on 30 April 2006. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from 1 July 2005 to 30 June 2006.
Tropical cyclones in this area are monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology in Perth, Darwin, and Brisbane; and TCWC Port Moresby in Papua New Guinea.
Systems
Tropical Low 02S
An area of convection persisted on 4 November about 560 km (350 mi) north of the Cocos Islands, associated with a tight low-level circulation. With good outflow and moderate but decreasing wind shear, conditions favored development. By early on 5 November, the system consisted of a partially exposed circulation with deep convection on its western side, tracking southwestward. At 0400 UTC that day, the Tropical Cyclone Warning Centre (TCWC) in Perth issued a gale warning in association with the disturbance. Later in the day, the Joint Typhoon Warning Center (JTWC) classified it as Tropical Cyclone 02S, and both the JTWC and TCWC Perth anticipated further strengthening.
Throughout its duration, TCWC Perth maintained the system as a 55 km/h (34 mph) tropical low.

The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Sep 3, 2026. The linked authority identifier is Q4605297. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2005 and 2006.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
