Constructed in the late nineteenth century, the Greenbushes Post Office was established to serve one of Western Australia's oldest mining communities.
As the town grew through timber milling and tin mining, the post office became an important communications hub, connecting residents and local industries with the rest of the State.
Today, the post office remains an important part of Greenbushes' heritage streetscape,
reflecting the town's unique mining history and the continuing significance of regional postal services
