Seven Mile Beach is a long beach with significant historical importance, located just south of Gerringong in the Shoalhaven area of New South Wales, Australia.
In 1933, Seven Mile Beach was used by Sir Charles Kingsford Smith as the runway for the first commercial flight between Australia and New Zealand.
The area contains a unique littoral rainforest with several rainforest plants at their southernmost limit of distribution, as well as a beach/dune/wetland ecosystem and has been used for studying sand dunes and their vegetation. Surrounding the beach are spinifex, coast wattle, tea-tree, coast banksia, she-oaks, saw banksia, southern mahogany or bangalay, and burrawangs. It also features a small river and a lake.
Its bird population includes honeyeaters, currawongs, crimson rosellas, thornbills, kookaburras, ravens, grey fantails, eastern whipbirds and white-throated treecreepers, and even white-breasted sea eagles.
