Rosa Brook

About Rosa Brook

Rosa Brook is a small rural locality in the Shire of Augusta-Margaret River, Western Australia, situated approximately 10 kilometres south-east of the Margaret River township and about 288 kilometres south of Perth. With a 2021 census population of 216 residents spread across roughly 65 square kilometres of rolling farmland and bushland, it is one of the quietest hamlets in the famous Margaret River wine region. The locality takes its name from Rosa Brook, a small stream that flows through the area.

Life in Rosa Brook centres on the land — residents are largely farmers, viticulturists, and lifestyle-block owners who appreciate the peace and space of semi-rural living within easy reach of Margaret River's world-class restaurants, cellar doors, and surf beaches. A historic general store, established by the Darnell family in 1932, long served as the community's social hub. Families and retirees are drawn to Rosa Brook for its tight-knit feel, clean air, and proximity to the region's natural attractions including the Leeuwin-Naturaliste National Park.

Rosa Brook falls under postcode 6285 and is governed by the local council Council (LGA). For state elections, residents vote in the Warren-Blackwood (South West) electorate.
