context_page_description: The 2004–05 Australian region cyclone season was a near-average season with eleven tropical cyclones occurring within the Australian region south of the equator and from 90°E to 160°E. The season officially ran from 1 November 2004 to 30 April 2005 with pre-season Tropical Cyclone Phoebe forming on 1 September and an unnamed tropical cyclone dissipating on 15 April. This is the period of the year when most tropical cyclones form within the Australian region.
  During the season at least five people were killed from tropical disturbances while overall damage was estimated at $15.4 million. Severe Tropical Cyclone Harvey caused an estimated $1 million in damage in Northern Territory when it made landfall in February. The most damaging storm of the season, Severe Tropical Cyclone Ingrid, killed five people and caused an estimated $14.4 million as the first tropical cyclone on record, to bring hurricane-force windspeeds to Queensland, Northern Territory, and Western Australia.
  Within the Australian region, tropical lows are monitored by the Bureau of Meteorology, who run Tropical Cyclone Warning Centres in Perth, Darwin and Brisbane.
