About Silverdale
Silverdale is a small town in Wollondilly Shire, south-western Sydney, situated approximately 72 kilometres west of the Sydney CBD at an elevation of 187 metres on the Cumberland Plain foothills adjacent to the Blue Mountains National Park. Established in 1828, the locality recorded a population of 4,543 at the 2021 census and covers 48.4 square kilometres of semi-rural residential land and surrounding bushland. Silverdale sits within the historic Camden County and is close to Warragamba Dam — the primary water supply reservoir for Greater Sydney — and the townships of Warragamba and Wallacia to the north-east. The Blue Mountains National Park forms a dramatic natural boundary on three sides, contributing to the area's scenic backdrop of sandstone escarpments and eucalypt forest.
Silverdale offers a semi-rural lifestyle that attracts Sydney families seeking larger blocks, clean air and natural surroundings while remaining within commuting distance of Western Sydney employment areas. The Camden town centre — approximately 30 minutes to the south-east — provides major retail, schools and medical services, while Penrith (approximately 25 kilometres north) offers train connections, Westfield shopping and a broader range of urban services. The Blue Mountains National Park is immediately accessible for bushwalking, cycling and rock climbing. Warragamba Dam's reservoir also provides opportunities for scenic drives and nature photography. Silverdale is earmarked within the broader South West Sydney growth corridor, with ongoing residential development in adjacent localities.
Silverdale falls under postcode 2752 and is governed by Wollondilly Council (LGA). For state elections, residents vote in the Wollondilly electorate.
