The 1980–81 Australian region cyclone season was an above average tropical cyclone season. It officially started on 1 November 1980 and officially ended on 30 April 1981.

Systems

Severe Tropical Cyclone Alice–Adelaide

Formed on 3 November, just south of Selat Mentawai then moved southwestward before reaching a peak intensity of 110 knots (125 mph, 205 km/h) and a minimum pressure of 940.0 hectopascals (27.76 inHg) on 8 November. On 12 November the storm began to move northwestward and two days later dissipated over the open Indian Ocean.

Severe Tropical Cyclone Bert–Christelle

The origins of Cyclone Bert–Christelle can be traced to a quasistationary convergence zone that spread across Indonesia to north of the Cocos Islands. Bert–Christelle was slow to organize but began to show signs of organization on November 26. Later on that day, the disturbance gained sufficient organization, noted by curved cloudbands, to be classified as Cyclone Bert. The cyclone moved to the southwest, gradually intensifying and attained a peak intensity of 150 km/h (95 mph) and a barometric pressure of 965 hPa (28.49 inHg) on November 29. Bert continued the same westerly motion and exited the basin on December 3. It was subsequently named Christelle by Météo France.^[1]

Severe Tropical Cyclone Carol

Category 5 severe tropical cyclone (Australian scale)
Category 3 tropical cyclone (SSHWS)

Duration	12 December – 22 December
Peak intensity	205 km/h (125 mph) (10-min); 940 hPa (mbar)

Cyclone Carol formed from a weak area of low pressure to the southwest of Timor on December 12. While moving to the southwest, the disturbance developed banding features and was classified as Cyclone Carol. As Carol moved to the west, it intensified and peaked at 195 km/h (120 mph) with a barometric pressure of 940 hPa (27.76 inHg) on December 16. Briefly, both Carol and Dan exhibited a Fujiwhara interaction around December 17 due to their close proximity to each other. Carol began to impart wind shear on nearby Cyclone Dan, ultimately leading to its demise. Carol continued its track, but encountered strong wind shear and rapidly weakened. Carol's low level center became decoupled and continued to the west, where it dissipated on December 24.^[2]

Tropical Cyclone Dan

Category 2 tropical cyclone (Australian scale)
Tropical storm (SSHWS)

Duration	14 December – 18 December
Peak intensity	95 km/h (60 mph) (10-min); 985 hPa (mbar)

Cyclone Dan formed from an area of convection situated north of the Cocos Islands in mid-December. The tropical low moved eastwards and curved to the southwest, coalescing to form Dan. Dan's track shifted abruptly to the northeast from interacting with Carol, attaining a peak intensity of 95 km/h (60 mph) and 985 hPa (29.08 inHg) on December 16. Intensification quickly halted as strong upper-level flow from Cyclone Carol to its south sheared its cloudtops off. Dan's low level circulation moved erratically to the south and passed within 140 km west of Christmas Island on December 17, where winds of 74 km/h were observed. Dan ultimately dissipated around 370 km to the south of Christmas Island on December 18. Cyclone Dan is notable in that it traveled generally towards the southeast for the duration of its existence, which is uncommon for cyclones in the area.^[3]

Tropical Cyclone Edna

Category 1 tropical cyclone (Australian scale)

Duration	20 December – 27 December
Peak intensity	75 km/h (45 mph) (10-min); 994 hPa (mbar)

Severe Tropical Cyclone Felix

Category 4 severe tropical cyclone (Australian scale)
Category 3 tropical cyclone (SSHWS)

Duration	22 December – 31 December
Peak intensity	185 km/h (115 mph) (10-min); 940 hPa (mbar)

Severe Tropical Cyclone Mabel

Category 5 severe tropical cyclone (Australian scale)
Category 4 tropical cyclone (SSHWS)

Duration	12 January – 21 January
Peak intensity	205 km/h (125 mph) (10-min); 930 hPa (mbar)

Tropical Cyclone Eddie

Category 2 tropical cyclone (Australian scale)
Tropical storm (SSHWS)

Duration	8 February – 13 February
Peak intensity	100 km/h (65 mph) (10-min); 980 hPa (mbar)

Tropical Cyclone Cliff

Category 2 tropical cyclone (Australian scale)
Tropical storm (SSHWS)

Duration	13 February (Crossed 160°E) – 15 February
Peak intensity	100 km/h (65 mph) (10-min); 980 hPa (mbar)

Initially a South Pacific tropical cyclone, Cliff developed on February 9, near Vanua Lava, Vanuatu. The cyclone reached peak intensity on February 12, with an estimated central pressure of 975 hPa. It passed over New Caledonia at near peak intensity, with sustained winds 92 km/h (57 mph). After crossing into the Australian region, Cliff struck Queensland on February 14, making landfall near Bundaberg. The cyclone caused some crop and structural damages in South East Queensland, and beach erosion occurred on the Gold and Sunshine coasts. One man was drowned off the Gold Coast.^[4]

Severe Tropical Cyclone Neil

Category 4 severe tropical cyclone (Australian scale)
Category 3 tropical cyclone (SSHWS)

Duration	24 February – 7 March
Peak intensity	195 km/h (120 mph) (10-min); 940 hPa (mbar)

Severe Tropical Cyclone Freda

Category 3 severe tropical cyclone (Australian scale)
Tropical storm (SSHWS)

Duration	24 February – 3 March (Crossed 160°E)
Peak intensity	130 km/h (80 mph) (10-min); 972 hPa (mbar)

Severe Tropical Cyclone Max

Category 3 severe tropical cyclone (Australian scale)
Category 3 tropical cyclone (SSHWS)

Duration	9 March – 19 March
Peak intensity	155 km/h (100 mph) (10-min); 960 hPa (mbar)

Cyclone Max developed from a low-pressure system into a Category 1 cyclone in Van Diemen Gulf, off the Northern Territory Coast, on 11 March 1981. Moving west-southwest, it crossed over Darwin, Australia later that day, causing tree damage and flooding but minimal structural damage. It subsequently moved west into the Timor Sea and the Indian Ocean, and although intensifying to Category 3 and reaching a lowest pressure of 960.0 hectopascals (28.35 inHg), did not approach land again.^[5] Max was notable for being the first cyclone to pass over Darwin since the city was destroyed by Cyclone Tracy 6 years earlier. The name Max was not retired from the Northern Australia naming list.
