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.
The 2002–03 Australian region cyclone season included Cyclone Inigo, which tied with Cyclone Gwenda in 1999 as the most intense tropical cyclone on record in the Australian basin. It began on 1 November 2002 and ended on 30 April 2003. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, which runs from 1 July 2002 to 30 June 2003. These dates conventionally delimit the period of each year when most tropical cyclones form in the Australian region, which is defined as in the southern hemisphere between 90°E and 180°E. The season's ten tropical depressions existed within these dates, with the first, designated as Tropical Cyclone 07S, entering the basin on 27 December 2002. The last system, Cyclone Epi, dissipated on 6 June 2003. Tropical cyclones in this area were monitored by four Tropical Cyclone Warning Centres (TCWCs): the Australian Bureau of Meteorology (BOM) in Perth, Darwin, and Brisbane and one in Port Moresby, Papua New Guinea.
The 2002–03 South Pacific cyclone season was the most active and longest tropical cyclone season since 1997–98, with ten tropical cyclones occurring within the South Pacific basin between 160°E and 120°W. The season started earlier than normal, with two systems developing before the official start of the season on November 1, 2002, while the final system dissipated on June 9, 2003, after the season had officially ended on April 30. During the season, tropical cyclones were officially monitored by the Regional Specialized Meteorological Centre (RSMC) in Nadi, Fiji and the Tropical Cyclone Warning Centres in Brisbane, Australia and Wellington, New Zealand. The United States Armed Forces through the Joint Typhoon Warning Center (JTWC), also monitored the basin and issued unofficial warnings for American interests. RSMC Nadi attaches a number and an F suffix to tropical disturbances that occur within the basin, while the JTWC designates significant tropical cyclones with a number and a P suffix. RSMC Nadi, TCWC Wellington and TCWC Brisbane all use the Australian Tropical Cyclone Intensity Scale and estimate windspeeds over a ten-minute period, while the JTWC estimates sustained winds over a one-minute period, which are subsequently compared to the Saffir–Simpson Hurricane Scale (SSHS).
The 1996–97 Australian region cyclone season was an above average tropical cyclone season. It ran from 1 November 1996 to 30 April 1997. The regional tropical cyclone operational plan also defines a tropical cyclone year separately from a tropical cyclone season, and the "tropical cyclone year" ran from 1 July 1996 to 30 June 1997.
Severe Tropical Cyclone Erica of March 2003 was a powerful cyclone that severely affected New Caledonia and was considered the worst to affect it since Cyclone Beti. The system was the eighth cyclone and the fifth severe tropical cyclone of the 2002–03 South Pacific cyclone season. Cyclone Erica developed from a monsoonal trough on 4 March just off Queensland. Originally, the storm moved slowly towards the east and then north early in its existence. However, increasing wind shear caused the storm to be degenerated into a tropical low. After conditions once again became more favorable for development, the remnants regenerated into a tropical cyclone on 10 March. Steadily intensifying, Erica reached peak intensity on 13 March as a Category 5 equivalent on the Australian intensity scale.
Severe Tropical Cyclones Katrina and Victor–Cindy were a long-lived pair of related tropical cyclones, which moved around the coast of northeastern Australia during parts of January and February 1998, before eventually moving into the southern Indian Ocean. Katrina was the fourth tropical cyclone and named storm of the 1997–98 Australian region cyclone season; Victor–Cindy was the seventh tropical cyclone and named storm of the 1997–98 Australian region cyclone season; after moving into the South-West Indian Ocean, Victor–Cindy became the fifth tropical cyclone and the fourth named storm of the 1997–98 South-West Indian Ocean cyclone season. Katrina developed on 1 January and meandered within the Coral Sea between the Queensland coast and Vanuatu for the next three weeks, before degenerating into a remnant low near Far North Queensland on 25 January. After its decay, the remnants of Katrina moved westward over Cape York Peninsula and the Gulf of Carpentaria, before regenerating into Cyclone Victor on February 8, after which the system moved through the Northern Territory and into the Indian Ocean, over the course of the next week. Upon reaching the Indian Ocean on 16 February, the system was named "Cindy" by Mauritius, before eventually dissipating on 19 February.
Severe Tropical Cyclone Aivu was a powerful late-season tropical cyclone that caused extensive damage across parts of Queensland, Australia in April 1989.
Severe Tropical Cyclone Yasi was a powerful and destructive tropical cyclone that made landfall in northern Queensland, Australia in early 2011, causing major damage to the affected areas. Originating as a tropical low near Fiji on 26 January, the system intensified to tropical cyclone status during the evening of 30 January. Yasi deepened rapidly over the next 24 hours, and was classified as a Category 3 cyclone at about 5 PM AEST on 31 January 2011. Late on 1 February, the cyclone strengthened to a Category 4 system; then, early on 2 February, the cyclone intensified into a Category 5 Severe Tropical Cyclone. The system had a well-defined eye and continued to track west-southwestward, maintaining a central pressure of 930 hPa and a Dvorak intensity of T6.5 into the evening.
Severe Tropical Cyclone Rewa affected six countries and caused 22 deaths on its 28-day journey across the South Pacific Ocean in December 1993 and January 1994. Cyclone Rewa developed from a tropical disturbance on 28 December south of Nauru. After forming, Rewa moved southwest through the Solomon Islands, crossing the 160th meridian east from the South Pacific basin into the Australian region. The cyclone began to strengthen steadily and turned southward, paralleling the eastern Australian coast through 31 December. Rewa reached its initial peak intensity as a Category 4 tropical cyclone on 2 January. It maintained this intensity for about 12 hours before an increase in wind shear induced its weakening by 3 January. The cyclone turned southeastward and moved back into the South Pacific basin on 4 January, before it passed over New Caledonia between 5–6 January. After affecting New Caledonia, Rewa weakened to a tropical depression and turned northwestward before re-entering the Australian basin on 10 January.
Severe Tropical Cyclone Jasmine was a powerful and long-lived annular tropical cyclone that affected several countries, particularly Vanuatu and Tonga, over a 16-day span in February 2012. The system was the second cyclone and the only severe tropical cyclone of the relatively quiet 2011–12 South Pacific cyclone season. Cyclone Jasmine developed from an area of disturbed weather on 1 February in the Gulf of Carpentaria. Initially, the storm moved towards the east and across the Cape York Peninsula. As it moved across the South Pacific, earlier existing wind shear conditions lessened, and Jasmine began to strengthen at a faster rate. Steadily intensifying, Jasmine reached peak intensity on 8 February as a Category 4 equivalent on the Saffir–Simpson Hurricane Scale, while beginning to show annular characteristics.
Severe Tropical Cyclone Fran was the third tropical cyclone within four weeks to impact Vanuatu in 1992. Fran formed on 4 March and then gradually intensified, with winds reaching gale-force on 5 March, and hurricane-force a few days later. Few days later, Cyclone Fran reached severe tropical cyclone status near Vanuatu, and also became a powerful Category 5-equivalent on the Saffir–Simpson Hurricane Scale. The storm weakened somewhat due to land interaction, but briefly re-intensified after moving away from land. Fran gradually weakened over the next several days over less favorable conditions. Meanwhile, the storm passed north of New Caledonia. Eventually, as a Category 2 system on the Australian scale, Fran made landfall on Queensland on 16 March. Afterwards, Cyclone Fran turned towards the southeast and eventually headed back out to sea, eventually dissipating the next day. On Efate, over 130 houses lost roofs. Along Queensland, two rivers sustained major flooding, but no deaths were attributed to this cyclone. Total damage from the system was AU$8–10 million. Moderate damage was also reported in Fiji. In New Caledonia, the storm brought flooding and landslides.
Severe Tropical Cyclone Beni was an intense tropical cyclone that affected four countries, on its 18-day journey across the South Pacific Ocean during January and February 2003. The system originally developed during 19 January as a weak tropical disturbance within the monsoon trough, to the northeast of the Santa Cruz Islands. Over the next few days the system gradually developed further before it was classified as a tropical cyclone and named Beni during 24 January.
Severe Tropical Cyclone Drena was a powerful tropical cyclone that caused significant damage throughout New Zealand. A tropical depression formed on January 2, 1997. After crossing Vanuatu and emerging into the Coral Sea, the storm began to intensify, and by January 6, had attained peak intensity. After attaining peak intensity, Drena began to weaken. Cyclone Drena later brushed New Caledonia, bringing some damage. After transitioning into an extratropical cyclone on January 9, Drena brought impact to New Zealand. Damage totaled to $6.7 million and 3 people were killed. Roughly 140 people were evacuated after 44 homes were flooded. After the season, Drena was retired.
Severe Tropical Cyclone Esau was the strongest tropical cyclone to affect New Caledonia on record. A shallow tropical depression developed within the monsoon trough during 24 February 1992, about 370 km (230 mi) to the northeast of Port Vila, Vanuatu. Over the next day, the system gradually developed further as it moved towards the south-west under the influence of a northerly steering flow, before it passed over Pentecost Island in northern Vanuatu during 25 February. After passing over Pentecost the system continued to move towards the southwest and passed near the island of Malampa before the depression turned northwards and executed a small clockwise loop as it passed over the island of Espiritu Santo. The system was subsequently named Esau during 26 February, after it had developed into a tropical cyclone. Over the next couple of days, the system moved south-westwards towards Australia and away from the islands of Vanuatu. Esau subsequently executed a second clockwise loop during 28 February, before it peaked as a Category 4 tropical cyclone on both the Australian tropical cyclone intensity scale and the Saffir-Simpson hurricane wind scale. After it had peaked the system moved south-eastwards and threatened Southern Vanuatu, before turning southwards and threatening the French overseas territory of New Caledonia. Esau made landfall on the French territory during 4 March, as a category 3 severe tropical cyclone before degenerating into an extratropical cyclone during 5 March. The systems remnants made landfall on New Zealand's North Island during 8 March, before they were last noted during the next day over the South Pacific Ocean.
Severe Tropical Cyclone Joy struck Australia in late 1990, causing the third highest floods on record in Rockhampton, Queensland. This cyclone began as a weak tropical low near the Solomon Islands, and initially moved westward. On 18 December, it was named Joy, becoming the 2nd named storm of the 1990–91 Australian region cyclone season. After turning southwest, Joy developed a well-defined eye and strengthened to maximum sustained winds of 165 km/h (103 mph) while approaching Cairns in Far North Queensland. Brushing the city with strong winds, the cyclone soon weakened and turned southeast. Joy later curved back southwest, making landfall near Townsville, Queensland on 26 December. It dissipated the next day; remnant moisture continued as torrential rainfall over Queensland for two weeks.
Severe Tropical Cyclone Winifred was the worst tropical cyclone to make landfall in northern Queensland and the first since Althea in 1971 to inflict significant damage on the northeastern coast of Australia. The sixth named storm of the 1985–86 Australian region cyclone season, Winifred originated as a tropical low north of Cairns, Queensland on 27 January 1986. Slowly organizing, the system was recognized as a tropical cyclone after gaining tropical characteristics on 30 January, christened with the name Winifred the same day. Meandering southward, the cyclone began to curve southeastward that evening before suddenly turning toward the coast, southwestward, on 31 January, steadily intensifying in that time. By the time it came ashore near Silkwood, Queensland at 0445 UTC on 1 February, it was producing Category 3-force winds on the Australian tropical cyclone intensity scale and a minimum atmospheric pressure of 957 mbar (28.38 inHg). Weakening as it drifted inland, Winifred persisted as a tropical depression for another five days after landfall before finally dissipating on 5 February.
Severe Tropical Cyclone Ita was the strongest tropical cyclone in the Australian region by central pressure since George in 2007, and by wind speed since Monica in 2006. The system was first identified over the Solomon Islands as a tropical low on 1 April 2014, and gradually moved westward, eventually reaching cyclone intensity on 5 April. On 10 April, Ita intensified rapidly into a powerful Category 5 system on the Australian Scale, but it weakened to a Category 4 system in the hours immediately preceding landfall the following day. At the time of landfall at Cape Flattery at 12 April 22:00 (UTC+10), the cyclone's Dvorak intensity was approximately T5.0, consistent with a weak Category 4 system, and considerably lower than the T6.5 observed when the system was at its peak intensity. Meteorologists noted the system had, at that time, begun an eyewall replacement cycle; as a result, the system was considerably less powerful than various intensity scales had predicted. As a result, Ita's impact on terrain was lessened.
Severe Tropical Cyclone Trevor was a powerful and large tropical cyclone that caused major damages across Papua New Guinea, Northern Territory and Queensland during March 2019. The twentieth tropical low, seventh tropical cyclone, and fourth severe tropical cyclone of the 2018-19 Australian region cyclone season, Trevor originated from a tropical low that formed to the east of Papua New Guinea.
Severe Tropical Cyclone Niran was a very powerful tropical cyclone that brought severe impacts to extreme Northeastern Australia and nearly made landfall in New Caledonia in February and March 2021. The sixth tropical cyclone and the second severe tropical cyclone of the 2020–21 Australian region cyclone season, while being the third severe tropical cyclone of the annual South Pacific cyclone season, Niran was the second Category 5 severe tropical cyclone in the South Pacific cyclone season, following Cyclone Yasa. The cyclone formed from a tropical low in the Coral Sea on 27 February. The tropical low gradually intensified while stalling offshore of Queensland for several days, although disorganized at the time. Early on 3 March, Niran pulled away from the coast of Australia, while it started undergoing rapid intensification. Eventually, Niran reached its peak intensity as a Category 5 tropical cyclone on both the Australian Tropical Cyclone Scale and the Saffir–Simpson scale, on 5 March, well offshore of Australia. Soon afterward, Niran initiated an eyewall replacement cycle and encountered some wind shear, causing the storm to weaken on 6 March, as it passed just to the south of Grande Terre, the main island of New Caledonia. Afterwards, Niran continued rapidly weakening as wind shear increased further, before transitioning into an extratropical cyclone late on 6 March. Niran was absorbed into another extratropical storm two days later.
Severe Tropical Cyclone Dinah was an intense tropical cyclone that impacted the southern coasts of Queensland and New South Wales, causing floods and landslides in 1967. It was regarded by an official in the Bureau of Meteorology's Brisbane Tropical Cyclone Warning Centre as the strongest storm to approach the southern coasts of Queensland since reliable records began. Forming on January 22 in the South Pacific basin, nearly 620 kilometers to the southeast of Honiara in the Solomon Islands, the disturbance that would eventually be Dinah remained disorganized until the next day when the system started to organize under the warm waters of the Coral Sea. On January 24, the disturbance was upgraded to a tropical cyclone by the BoM and was named Dinah, being the fifth storm in the records of the meteorology center of Australia in the 1966–67 Australian region cyclone season. Environmental conditions favoured Dinah to further intensify, becoming a severe tropical cyclone on January 27 while recurving south-southwestwards. On the next day, it passed through the Great Barrier Reef as a Category 4 severe tropical cyclone before passing through Fraser Island on January 29, where the Sandy Cape Lighthouse recorded a minimum barometric pressure of 944.8 hPa on Dinah, being the lowest known pressure of the system. It then battered the whole island before turning south-southeastwards, away from the coast of Queensland. Weakening took place while slowing down, passing near Lord Howe Island as a Category 2 tropical cyclone before undergoing extratropical transition on January 31. Dinah became extratropical on the night of that day before accelerating eastward, approaching New Zealand. The system then turned southeastward for the final time before passing through the North Island. It reemerged on the Southern Pacific Ocean on February 3, where it dissipated.
