The 1983–84 Australian region cyclone season was one of the most active seasons on record. It officially started on 1 November 1983, and officially ended on 30 April 1984.
Cyclone 01S existed over the northwestern areas of the Australian region basin from 11 July to 15 July.
Oscar developed from a low pressure area to the northwest of the Cocos Islands on 22 October. The storm moved generally southward for several days before dissipating on 1 November.
A low pressure developed into Pearl on 11 November. The system tracked southeastward and ceased to exist on 14 November.
Quenton developed on 26 November from a low pressure situated south of Java. Making landfall in Western Australia on 29 November, Quenton was the first tropical cyclone to strike Australia in the month of November since Ines in 1973. The cyclone dissipated on the following day.
On 9 December, Fritz developed from a low pressure area to the northwest of Willis Island. Fritz meandered erratically until dissipating on 13 December.
A small, weak tropical low, later named Esther, developed over the Banda Sea on 19 December. Esther struck Babar Island and then dissipated on 21 December.
Operationally, this cyclone was considered to have been the redeveloped remnants of Esther. The storm developed from a cloud cluster near the southern tip of Timor on 21 December. The system moved west-northward and dissipated on 24 December.
A low pressure area rapidly developed into Tropical Cyclone Sharon on 25 December. Sharon existed west of 90°E, which is now the western boundary of the Australian region basin. The storm dissipated on 31 December.
Tim formed from a low pressure area to the southeast of Christmas Island on 2 January 1984. After moving northwest, Tim turned southward on 6 January. The cyclone decayed to a tropical low by 10 January.
A weak area of low pressure developed east of Queensland on January 11. The tropical disturbance moved northeastward over the Coral Sea and gradually became better organized. On January 13 it turned to the south and intensified into a tropical cyclone the next day. In a favorable environment for intensification, Grace strengthened on January 15 and 16, developing a ragged eye as seen on the satellite images. On January 16 became a severe tropical cyclone and reached its lowest estimated pressure of 970 mb. Also on January 16, a weather station on Frederick Reef reported maximum winds of 130 km/h. On January 17, upper level shear increased over the circulation and Grace became exposed as the tropical cyclone turned to the east. Weakening continued during the next few days and Grace decayed into a remnant low on January 21 while located southeast of Noumea.
