The 2014–15 Australian region cyclone season was a slightly below average tropical cyclone season, though it featured numerous intense cyclones. The season officially ran from 1 November 2014, to 30 April 2015, however, a tropical cyclone could form at any time between 1 July 2014, and 30 June 2015, and would count towards the season total. During the season, tropical cyclones were officially monitored, by one of the five Tropical Cyclone Warning Centres (TCWCs) that are operated in this region.

Three of the five centres are operated by the Australian Bureau of Meteorology (BoM) in Perth, Darwin, and Brisbane, while the other two are operated by the National Weather Service of Papua New Guinea in Port Moresby and the Indonesian Agency for Meteorology, Climatology and Geophysics in Jakarta, Indonesia. The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services, including Météo-France, also monitored the basin during the season.

Ahead of the cyclone season, the Australian Bureau of Meteorology (BoM), the New Zealand National Institute of Water and Atmospheric Research (NIWA) and various other Pacific Meteorological services, all contributed towards the Island Climate Update tropical cyclone outlook that was released during October 2014.{{cite web|url=http://img.scoop.co.nz/media/pdfs/1410/TCforecast.docx|title=Southwest Pacific Tropical Cyclone Outlook: Near-average tropical cyclone numbers for the region is likely, with increased activity from February onward|publisher=The National Institute of Water and Atmospheric Research|date=15 October 2014|access-date=22 October 2014}} The outlook took into account the ENSO neutral conditions that had been observed across the Pacific and analogue seasons that had ENSO neutral and weak El Niño conditions occurring during the season. The outlook called for a near average number of tropical cyclones for the 2014–15 season, with eight to twelve named tropical cyclones, to occur between 135°E and 120°W compared to an average of 10. At least four of the tropical cyclones were expected to become category 3 severe tropical cyclones, while three could become category 4 severe tropical cyclones, they also noted that a Category 5 severe tropical cyclone was unlikely to occur.

In addition to contributing towards the Island Climate Update outlook, the BoM issued eight seasonal forecasts during October 2014, for the Australian region and the Southern Pacific with each forecast covering the whole tropical cyclone year. Each forecast issued took into account the near El Niño conditions that had developed over the region and the El Niño episode that was expected to develop during the season. For the basin as a whole, they predicted that there was a 34% chance, that the season would be near its average of around 11 tropical cyclones. For the Western region between 90°E and 125°E, the BoM forecast that the area would see activity near to the average of 7, with a 43% chance of an above-average cyclone season. TCWC Perth also noted that there was a likelihood of two tropical cyclones and a significant likelihood of at least one severe tropical cyclone impacting Western Australia.{{cite web|publisher=Australian Bureau of Meteorology |title=Western Australia Seasonal Tropical Cyclone Outlook |url=http://www.bom.gov.au/cyclone/outlooks/seasonal/wa.shtml |access-date=13 October 2014 |author=Perth Tropical Cyclone Warning Centre |archive-url=https://web.archive.org/web/20141012211822/http://www.bom.gov.au/cyclone/outlooks/seasonal/wa.shtml |archive-date=12 October 2014 |date=13 October 2014 |url-status=live |df=dmy }}

For the North-Western subregion between 105°E and 130°E, it was predicted that activity would be below average, with a 38% chance of above average tropical cyclone activity. The Northern Territory which was defined as being between as being 125°E and 142.5°E had a 46% chance of an above average season, with TCWC Darwin noting that all of the climate drivers were pointing towards a typical tropical cyclone season for Northern Australia.{{cite web|publisher=Australian Bureau of Meteorology|title=Tropical Cyclone Seasonal Outlook for the Northern Territory|url=http://www.bom.gov.au/cyclone/outlooks/seasonal/nt.shtml|archive-url=https://web.archive.org/web/20140116010101/http://www.bom.gov.au/cyclone/outlooks/seasonal/nt.shtml|access-date=16 January 2014|author=Darwin Tropical Cyclone Warning Centre|archive-date=16 January 2014|date=14 October 2013|url-status=dead}} The Eastern region between 142.5°E and 160°E was predicted to have a near normal tropical cyclone season, though it was noted that there was a possibility of a delayed start to the season.{{cite web|publisher=Australian Bureau of Meteorology |title=Tropical Cyclone Seasonal Outlook for The Coral Sea |url=http://www.bom.gov.au/cyclone/outlooks/seasonal/qld.shtml |access-date=13 October 2014 |archive-url=https://web.archive.org/web/20141011023939/http://www.bom.gov.au/cyclone/outlooks/seasonal/qld.shtml |archive-date=11 October 2014 |date=13 October 2014 |url-status=live |df=dmy }} The BoM also issued 3 seasonal forecasts for the Southern Pacific between 142.5°E and 120°W, one for the Western Southern Pacific region between 142.5°E and 165°E and one for the Eastern Southern Pacific region between 165°E and 120°W. They predicted that the region as a whole would experience near average tropical cyclone activity during the coming season with a 55% chance of it being above average. The Western region was predicted to have 39% chance of being above average while the Eastern region had a 55% chance of being above average.

An updated Island Climate Update tropical cyclone outlook was issued during February 2015, which suggested that near normal activity was still possible.{{cite web|url=http://www.niwa.co.nz/news/southwest-pacific-tropical-cyclone-outlook-update |title=Southwest Pacific Tropical Cyclone Outlook Update |date=9 February 2015 |archive-date=28 March 2015 |archive-url=https://web.archive.org/web/20150328225850/http://www.niwa.co.nz/news/southwest-pacific-tropical-cyclone-outlook-update |publisher=National Institute of Water and Atmospheric Research |access-date=18 March 2015 |url-status=live |df=dmy }} The outlook took into account Tropical Cyclones Niko and Ola as well as the weak El Niño conditions, that were predicted to persist over the region. As a result, the update predicted that an additional six to eight named tropical cyclones would develop over the basin, which would bring the overall total to between eight and ten tropical cyclones. The update also predicted that at least four tropical cyclones would intensify into category three severe tropical cyclones, of which three could intensify and become either a category four or five severe tropical cyclones.

As computer models were predicting conditions surrounding the low to be marginally favourable for further development, TCWC Perth expected the system to develop into a tropical cyclone and issued tropical cyclone advice for coastal areas from Kuri Bay to Exmouth. However, as the system spent more time over land than had been forecasted and vertical wind shear did not weaken as much as forecasted. As a result, the system failed to develop into a tropical cyclone as it moved south-westwards towards the Pilbara coast before it dissipated near Port Hedland during 20 January.

Cyclone Lam was the strongest storm to strike Australia's Northern Territory since Cyclone Monica in 2006. It formed from the monsoon trough on 12 February in the Coral Sea. For much of its duration, the system moved westward due to a ridge to the south. The system crossed over the Cape York Peninsula and moved into the Gulf of Carpentaria, whereupon it gradually organized due to warm waters and favorable outflow. On 16 February, the Bureau of Meteorology (BoM) classified it as a Category 1 on the Australian tropical cyclone intensity scale and gave it the name Lam. The storm intensified further while drifting toward the Wessel Islands, developing an eye and strengthening to the equivalence of a minimal hurricane on 18 February. It strengthened to reach maximum sustained winds of {{convert|185|km/h|mph|abbr=on|round=5}} early on 19 February before turning to the southwest, making it a Category 4 cyclone. That day, it made landfall on Northern Territory between Milingimbi and Elcho Island at peak intensity, and it rapidly weakened over land. About six hours after Lam moved ashore, Cyclone Marcia struck Queensland as a Category 5 cyclone, marking the first time on record that two storms of Category 4 intensity struck Australia on the same day.

In its formative stages, Lam produced heavy rainfall and flooding in Far North Queensland. Later, the cyclone's rainfall set daily precipitation records in Northern Territory. However, the winds caused the most damage, with gusts estimated as high as {{convert|230|km/h|mph|abbr=on|round=5}}. The highest gust was {{convert|170|km/h|mph|abbr=on|round=5}} at Cape Wessel on Rimbija Island. Lam caused considerable destruction, particularly affecting local aboriginal communities. Total damage in the Northern Territory reached at least A$82.4 million (US$64.3 million).

On 16 February, the BoM started to monitor a weak tropical disturbance in the Coral Sea. It quickly developed into a Category 1 tropical cyclone on 18 February, earning the name Marcia. It was upgraded to Category 2 the following day when it was approximately {{convert|555|km|mi}} north of Bundaberg and again upgraded to Category 3 severe tropical cyclone when approximately {{convert|290|km|mi}} north of Yeppoon. On 19 February, due to a developing, clear eye, the JTWC upgraded Marcia to a Category 2 whilst the BoM upgraded it as a Category 4. Due to explosive intensification, Marcia became a Category 5 according to the BoM early on 20 February. It affected Queensland, and last noted on 26th of the same month as it dissipated, west-southwest of New Caledonia.

On 8 March, the BoM started to monitor a weak tropical low over Western Australia. The system was later designated as 16U a few days later. Due to an increase in convection, both the BoM and JTWC upgraded the system to a Category 1 tropical cyclone, naming it Olwyn on 11 March. Just before 12 March, Olwyn rapidly developed a ragged eye, as the BoM upgraded the system to a Category 3 severe tropical cyclone. Early on 13 March, Olwyn reached its peak strength of 140 km/h (85 mph) as the JTWC classified it as a Category 2 cyclone. However, after a few hours, the JTWC downgraded it to a Category 1 cyclone as it weakened from land interaction. On the same day, Olwyn made landfall over southwestern Australia as a weakening cyclone. Rapidly weakening inland, it emerged on the Southern Ocean as a decaying remnant low. It dissipated onwards.

Olwyn caused extensive damage along the coast of Western Australia, from Onslow to Kalbarri. In preparation for the storm, the Pilbara Ports authority closed the ports of Dampier and Ashburton.{{Cite news |url=http://www.perthnow.com.au/news/western-australia/cyclone-olwyn-live-updates/story-fnhocxo3-1227262071011 |archive-url=https://web.archive.org/web/20150314063843/http://www.perthnow.com.au/news/western-australia/cyclone-olwyn-live-updates/story-fnhocxo3-1227262071011 |url-status=dead |archive-date=14 March 2015 |title=Cyclone Olwyn: Live updates |access-date=21 March 2015 |date=14 March 2014 |publisher=Perth Now }} The entire workforce on Barrow Island was evacuated to the island's cyclone shelter.{{cite web|work=Daily Observations|publisher=Weatherzone|date=12 March 2015|access-date=22 March 2015|title=Barrow Island 24 Hour Observations|url=http://www.weatherzone.com.au/station.jsp?lt=site&lc=5094&dt=12%2F03%2F2015}} Upon landfall, a maximum wind gust of {{convert|180|km/h|abbr=on}} was recorded at Learmonth.{{cite web|work=Daily Observations|publisher=Weatherzone|date=13 March 2015|access-date=22 March 2015|title=Learmonth 24 Hour Observations|url=http://www.weatherzone.com.au/station.jsp?lt=site&lc=5007&dt=13%2F03%2F2015}} Trees were uprooted and power was cut for several days.{{cite web|author=Daniel Smith and Geoff Boughton |publisher=James Cook University |date=16 March 2015|access-date=22 March 2015|title=Cyclone Olwyn Rapid Damage Assessment Report |url=https://www.jcu.edu.au/cts/publications/content/cyclone-olwyn-rapid-damage-assessment-report/view}} Damage was more severe further south at Carnarvon where most houses are not built to cyclone standards, unlike in Exmouth.

Shortly after Cyclone Pam was classified on the South Pacific, the outer rainbands of Pam led to the formation of a tropical low near Australia on 9 March. Later that day, the BoM designated the system as 17U and intensified into Tropical Cyclone Nathan several hours later. It slowly executed a cyclonic loop over the next few days, moving across Arnhem Land.{{cite news|last=Purtill|first=James|title=Cyclone Nathan: Cyclone-ready Northern Territory town of Nhulunbuy hit harder than ever before|url=http://www.abc.net.au/news/2015-03-22/prepared-nhulunbuy-community-weathers-cyclone-nathan/6339396|access-date=23 March 2015|agency=ABC News}} {{citation needed span|After intensifying to an initial peak intensity of {{convert|165|km/h|mph|abbr=on|round=5}}, Nathan weakened while crossing the Cape York Peninsula and reintensified over the Gulf of Carpentaria.

On 6 April, the BoM had reported that Ikola had entered the basin as a severe tropical cyclone from the Southwest Indian Ocean basin and was designated as 19U. Ikola rapidly weakened due to moving into a region of increasing wind shear, becoming a category 3 tropical cyclone by the evening of 7 April. Along with decreasing sea surface temperatures and further increases of wind shear caused Ikola to weaken more to a tropical low on the afternoon of 8 April. The low then proceeded to become a trough system, bringing heavy rainfall to the southwestern parts of Western Australia and severe storms to the southeast of Western Australia. Ikola soaked Central Western Australia and affected Perth from 6–12 April.

Ikola was also the first cyclone to move into the Australian basin from the Southwest Indian Ocean basin since Cyclone Alenga in 2011.

On 27 April, the BoM started to monitor a tropical low over Western Australia that had formed from a monsoon trough. Later that day, the system gradually intensified as it was designated as 21U. The next day, 21U intensified into Tropical Cyclone Quang. Quang proceeded to intensify rapidly during 29 and 30 April, reaching a maximum intensity of a category 4 severe tropical cyclone. Quang was located 600 km northwest of the North West Cape region before turning in a southeast direction. Quang moved southeast during 1 May while rapidly weakening due to an increase of wind shear, disrupting the cyclones structure in the process. Quang was downgraded to a category 3 severe tropical cyclone in the morning of 1 May and continued to weaken during the course of the day, becoming a Category 1 before making landfall near the Exmouth coast on the night of 1 May and quickly weakened to a tropical low after it hit Exmouth. It dissipated thereafter. Quang did minimal damage to Exmouth, Western Australia.{{cite news|author=Bureau of Meteorology|access-date=25 May 2017|title=Tropical Cyclone Quang|url=http://www.bom.gov.au/cyclone/history/quang.shtml}}

Late on 30 June, Tropical Depression 17F moved into the Australian region from the South Pacific and intensified gradually into Tropical Cyclone Raquel. After drifting for the next two days, it exited the basin, moving back into the South Pacific. However, Raquel re-entered the basin early on 4 July as a weakening depression. The next day, Raquel was declared a remnant low.

According to the Bureau of Meteorology, it is the only known instance of a tropical cyclone during July in the region since the satellite era began (since at least 1970) until Tropical Cyclone 01U in 2022.{{cite news|author=Bureau of Meteorology|access-date=19 March 2016|title=Tropical Cyclone Raquel Impacts|url=http://www.bom.gov.au/announcements/sevwx/qld/qldtc20150630.shtml}} As a byproduct of becoming a tropical cyclone on the first day of the new cyclone year, it marked the earliest start to a season in the basin on record.{{cite news|author=Peter Hannam|newspaper=The Sydney Morning Herald|date=1 July 2015|access-date=2 July 2015|title=Cyclone Raquel forms as earliest big storm recorded off Australia's north-east |url=http://www.smh.com.au/environment/weather/cyclone-raquel-forms-as-earliest-big-storm-recorded-off-australias-northeast-20150701-gi23c7.html}}

Storm names

During the season a total of 7 tropical cyclones received a name from BoM, either by TCWC Perth, Darwin, or Brisbane, when the system was judged to have 10-minute sustained windspeeds of {{convert|65|km/h|mph|round=5|abbr=on}}. There has only been one list that the Bureau of Meteorology have assigned names to tropical cyclones since the 2008–09 season. Moreover, TCWC Jakarta named its first cyclone since 2010, and used the name Bakung. Tropical cyclones named by the TCWC Port Moresby are rare, with the last named cyclone occurring during 2007.
