Tracking towards the southeast, the low experience strong deep-level wind shear which kept most of the convection displaced from the center of circulation.

[4] The system moved southeast and entered the Perth Tropical Cyclone Warning Centre's area of responsibility on 1 September.

The cyclone weakened over land, and the remnant low continued east over the Northern Territory, entering the Gulf of Carpentaria on 5 January.

Cyclone Sally slowly moved to the southwest, under the influence of a mid-level ridge to the southeast, reaching its peak with 95 km/h winds on 9 January.

The storm then rapidly weakened as a result of the presence of dry air and increased wind shear, before dissipating early on 10 January 460 km west-southwest of the Cocos Islands.

A tropical low located about 930 km north of Learmonth, Western Australia began to develop a deeper convection on 23 January, despite being beneath the subtropical ridge.

Tim lost tropical cyclone status on 25 January to 470 km south-west of Christmas Island and the remnant continued west before dissipating.

A tropical low formed north of the Gulf of Carpentaria on 3 March, before crossing the Cape York Peninsula and into the Coral Sea.

After peaking, Ingrid weakened to a category 4, making landfall on the Cape York Peninsula late on 9 March before emerging once again into the Gulf of Carpentaria.

In the Gulf, Ingrid once again rapidly intensified, achieving its second and strongest peak on 11 March with winds of 230 km/h (140 mph) and a pressure of 924 hPa (27.3 inHg).

Later that day, Ingrid made its final landfall near Kalumburu on the Kimberley coast and rapidly weakened, falling below cyclone status on 17 March.

Willy moved slowly west-southwest, roughly parallel to the Australian coast, strengthening steadily in the favourable environment.

[13] Cyclone Adeline triggered gale warnings on the Cocos Islands, where 160 mm of rain fell in one day.

[14][15] Over the next couple of days the system moved eastwards, with deep atmospheric convection developing over the western quadrants by 15 April.

[14][15] The system subsequently approached and interacted with south-eastern Papua New Guinea, before it moved into an area of increasing vertical wind shear and started weakening.
