History

Woronora is derived from an Aboriginal word wooloonora, meaning 'black rock'. It is believed to have been named by Surveyor Dixon in 1828.

Landmarks

Woronora Heights is bounded by the Woronora River in the west, the top of the escarpment in the north and the Metropolitan Water Sewerage and Drainage Board pipeline in the east and south. The Woronora Reservoir is one of the sources of Sydney's water supply.

The Woronora Plateau, is a geographical region adjacent to the Sydney Plain. Slightly higher in altitude, it is capped with Hawkesbury Sandstone. It is often hotter in summer and colder in winter than Sydney. The Woronora River flows through the deeply dissected plateau to the Georges River from near the sources of the Port Hacking, within the Sutherland Shire.
