Fumina South is a locality in Victoria, Australia. Located on Willowgrove Road, in the Shire of Baw Baw, it is an isolated pocket near the foothills of Mount Baw Baw. Fumina South has a population of approximately 50 people, mostly weekend farmers and retirees, although it was once a bustling community with its own post office and school.
The Post Office opened in 1907 as Duggan, was renamed Fumina South in 1925 and closed in 1962.
