About Lucas Heights

Lucas Heights is a unique suburb in southern Sydney, located 31 kilometres southwest of the CBD in the Sutherland Shire. With a population of just 4 at the 2021 census across 9.9 square kilometres, it is effectively an institutional rather than residential suburb. Lucas Heights is home to the ANSTO (Australian Nuclear Science and Technology Organisation) campus, which operates Australia's only nuclear research reactor, OPAL, and the Australian Synchrotron's sibling facility.

Lucas Heights is dominated by the ANSTO nuclear research facility, making it one of Sydney's most unusual suburbs. The surrounding area is largely bushland, with the Lucas Heights Resource Recovery Park (waste facility) also located within the suburb. Despite its proximity to residential Barden Ridge and Engadine, the suburb itself has virtually no permanent residents. It is significant nationally as the centre of Australia's nuclear science research and the production of nuclear medicine.

Lucas Heights falls under postcode 2234 and is governed by the local council Council (LGA). For state elections, residents vote in the Miranda electorate.
