Below is a timeline of the 2007-08 Australian region cyclone season, documenting all the storm formations, strengthening, weakening, landfalls, extratropical transitions, as well as dissipation.

The 2007-08 Australian region cyclone season was an event in the ongoing cycle of tropical cyclone formation. It officially started on November 1, 2007, and ended April 30, 2008. However, the formation of a tropical cyclone on July 27, 2007 marked an earlier beginning to the season. The regional tropical cyclone operational plan also defines a "tropical cyclone year" separately from a "tropical cyclone season"; the "tropical cyclone year" began on July 1, 2007 and will end on June 30, 2008.
