Originally a farming and viticulture district, the area was transformed by the construction of the Happy Valley Reservoir in the 1890s. Major residential development occurred between the 1960s and 1980s, turning it into a primary southern commuter hub.
A quiet, established residential suburb dominated by large family homes on sloping blocks with a strong emphasis on outdoor recreation and community safety.
