The United States Joint Typhoon Warning Center (JTWC) and other national meteorological services, including Météo-France, also monitored the basin during the season.

[1] 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.

[7] 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.

[7] On 3 December, TCWC Perth reported that Tropical Low 01U had developed over open water to the southwest of Cocos (Keeling) Islands, after various applications of the Dvorak technique had produced results between T2.0 and T3.0.

[13] TCWC Jakarta subsequently named the low Bakung during 11 December, as it was thought that the system had become a Category 2 tropical cyclone on the Australian Scale.

[14][15] At the same time, TCWC Jakarta reported that Bakung had peaked with 10-minute sustained windspeeds of 65 km/h (40 mph) before the JTWC initiated advisories on the system later that day and designated it Tropical Cyclone 03S.

[19][20] However, during that day the system's low-level circulation centre became exposed and displaced about 280 km (175 mi) from the deep convection.

[20][21][22] On 21 December, TCWC Perth reported that Tropical Low 04U had developed within the monsoon trough to the southeast of Sumatra, Indonesia.

The next day, Kate continued to intensify as an eye developed and reached peak intensity as a Category 4 severe tropical cyclone as.

On 30 December, the BoM reported that Kate had moved out of the Australian region and into the South-West Indian Ocean basin with 10-minute sustained winds of 150 km/h (90 mph).

On 2 January, TCWC Perth and Darwin started to monitor Tropical Low 05U, that had developed within the monsoon trough near Wyndham in the Kimberley region of Western Australia.

It gradually moved on the south, passing just east of Australia, before it was last noted on the 13th of the same month as it dissipated to the northwest of New Caledonia.

[32] 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.

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 185 km/h (115 mph) 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.

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.

[38] Olwyn passed over the town at category 3 status, unroofing and severely damaging multiple houses, while many sheds and outbuildings were totally destroyed.

[42] After intensifying to an initial peak intensity of 165 km/h (105 mph), Nathan weakened while crossing the Cape York Peninsula and reintensified over the Gulf of Carpentaria.

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.

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.

[48][49] 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 65 km/h (40 mph).
