The 2017-18 Australian region cyclone season is the period of the year when most tropical cyclones form within the Southern Indian Ocean and Pacific Oceans between 90°E and 160°E. The season officially runs from November 1, 2017 to April 30, 2018, however a tropical cyclone could form at any time between July 1, 2017 and June 30, 2018 and would count towards the season total. During the season, tropical cyclones will be 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 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.

Storm names[]
TCWC Jakarta[]
TCWC Jakarta monitor Tropical Cyclones from the Equator to 11S and from 90E to 145E. Should a Tropical Depression reach Tropical Cyclone strength within TCWC Jakarta's Area of Responsibility then it will be assigned the next name from the following list. This the first time that a tropical cyclone was named by TCWC Jakarta since 2014.
- Cempaka
TCWC Port Moresby[]
Tropical cyclones that develop north of 11°S between 151°E and 160°E are assigned names by the Tropical Cyclone Warning Centre in Port Moresby, Papua New Guinea. Tropical cyclone formation in this area is rare, with no cyclones being named in it since 2015. As names are assigned in a random order the whole list is shown below.
- Alu
Bureau of Meteorology[]
Since the start of the 2008–09 season, there has only been one list that the Bureau of Meteorology have assigned names to tropical cyclones from. However the Bureau of Meteorology still operates the various TCWCs in Perth, Darwin & Brisbane. They monitor all tropical cyclones that form within the Australian region, including when tropical cyclones exist in either TCWC Jakarta's or Port Moresby's area of responsibility.
