Peppermint Grove, WA
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Peppermint Grove is a small, affluent suburb on the north bank of the Swan River at Freshwater Bay, in Perth's western suburbs. It takes its name from the Swan River peppermint trees that still line many of its streets, and has long been associated with some of Western Australia's oldest and wealthiest families. The whole suburb forms its own local government area, the Shire of Peppermint Grove, which is the smallest in the country. Its prosperity shows in a number of grand historic houses, among them The Cliffe and the Federation Queen Anne residence St Just. The streets carry the names of the suburb's first residents, who bought lots when the land was subdivided in 1891. Riverfront reserves and jetties line the Freshwater Bay shore, and the shared Grove Library serves the surrounding districts.
