Peppermint Grove Beach is a residential subdivision and beachside town in the South West region of Western Australia.

In 1874, Charles Manning (Clerk of Works) had the cut built by the last of the convicts from the Bunbury depot which closed the same year.

People often camped on the land in the valley near the safe swimming spot and during the popularity of the place, it became known as Peppermint Grove.

His daughter Kathleen McCourt married Robert Hardey in 1904, after having helped run the farm for a number od years, continued to do so after her husband died in 1933.

After the war, Alex Campbell settled his family with Mrs Hardey, purchased some land and managed the property.

During World War II, the Australian Army established a lookout tower on top of the main dune - the highest point between Bunbury and Busselton - to look out for Japanese warships.
