Castlereagh, New South Wales, Australia is located east of the Nepean River north of Penrith. This suburb is one of the most historic sites in Australia’s history, being one of Governor Lachlan Macquarie’s five towns founded in 1810. After two hundred years, the rich river flats continue to provide for a thriving agricultural industry along the Nepean River. Many of this district’s pioneering families originated from Castlereagh. The suburb’s historical importance is reflected in its many surviving farmhouses, outbuildings, churches and cemeteries. Castlereagh Road is an important transport link connecting the Hawkesbury and Penrith regions. The impact of the massive Penrith Lakes Scheme has, and will in the future, change the face of Castlereagh and its neighbouring suburbs.

Landscape Profile

Castlereagh Woodlands

The Castlereagh Woodlands are found on the Tertiary alluvial deposits and include Ironbark Forest, Scribbly Gum Woodland and Swamp Woodland, each growing in slightly different conditions. Ironbark forest with Broad-leaved Ironbark, Eucalyptus fibrosa is found on deep, well-drained reddish clay soils; examples can be seen around Castlereagh. Eucalyptus fibrosa is the dominant tree species, generally forming pure stands, but it may also be associated with Mugga Ironbark, Eucalyptus sideroxylon and Narrow – leaved Ironbark, Eucalyptus crebra. A small tree layer of Melaleuca decora and an understorey of sclerophyllous shrubs to 2 m high is generally conspicuous. No particular species predominates in the understorey, although the pea family Fabaceae is well represented. Shrub species which may be locally abundant are Dillwynia tenuifolia, Dodonaea falcata, Hakea sericea, Melaleuca nodosa, Mirbelia rubiifolia and Pultenaea villosa. A number of species and forms are endemic to the Castlereagh Woodlands.

Scribbly Gum Woodland is found on sandy soils of the Tertiary alluvium, in the Castlereagh-Londonderry area and at Holsworthy. Eucalyptus sclerophylla and Angophora bakeri are the most common species. Other tree species that may be present are Eucalyptus fibrosa, Eucalyptus eugenioides, and very rarely, Eucalyptus gummifera. The understorey; consists of sclerophyllous shrubs which may form a continuous cover or be more open, with grasses in between. Common shrub species are Banksia spinulosa, Grevillea mucronulata, Hakea sericea, Leptospermum trinervium and Melaleuca nodosa. Swamp Woodland with Eucalyptus parramattensis, Eucalyptus sideroxylon and Melaleuca decora is found in poorly drained situations. Open-forest of Eucalyptusfibrosa is found with Grey Box, Eucalyptus moluccana, on the transitional zone between Wianamatta Shale and Tertiary alluvium. A mixture of species is found on these two soil types. Eucalyptus fibrosa, one of the most common species on the Tertiary alluvium and Eucalyptus moluccana, a common species on Wianamatta Shale, dominate. Other tree species present include Eucalyptus eugenioides and Eucalyptus sclerophylla. The understorey is dominated by low shrubs with a mixture of the hardier species from the Wianamatta Shale and Tertiary alluvium. Bursaria spinosa, Daviesia ulicifolia, Dillwynia juniperina, Hardenbergia violacea, Exocarpus cupressiformis, Melaleuca nodosa and Acacia parramattensis are the most common species. Small trees of Melaleuca decora are often conspicuous.

Penrith Lakes


  • Total area – 1,935 ha
  • Water source – Nepean River
  • Urban Land – 250 ha
  • Recreation Land – 1000 ha
  • Water Area – 750 ha
  • The total lineal extent of lake foreshore will be about 40 km – and the frontage to the Nepean River about 11 km. The area 3 km north of Penrith, known now as the Penrith Lakes Scheme and operated by a conglomerate of companies that combined their landholdings and quarrying operations in 1979 (i.e. Boral, CSR, and Pioneer International), is by far the largest extraction site in the area. This site supplies around 75% (140 tonnes of sand and gravel) of Sydney’s sand and crushed aggregate requirements, including about 85% of the materials for ready mixed concrete.
  • Penrith Lakes Development Corporation (PLDC) administered the lakes and mining operations. It was formed when three quarry companies joined together in 1980 to form the Corporation. At the time PLDC was formed, the Castlereagh quarry site produced most of the sand and gravel for the greater Sydney construction market.

    PLDC is also responsible in the rehabilitation of the site by constructing parkland and a system of lakes which will serve both as flood mitigation and outdoor recreational playground and residential development areas. The transformation of the site is well under way

    PLDC states it is ‘committed to the site for many years to come, to oversee the completion of the original Penrith Lakes Scheme vision – creating a natural and environmental wonderland of lakes, parkland and native bush as a setting for some of Sydney’s most desirable home sites’.

Historical profile

Origin of the place name – Castlereagh

This suburb takes its name from the Irish peer, Lord Viscount Castlereagh (1769-1822), who was responsible for the Act of Union between Ireland and England in 1803. Governor Lachlan Macquarie named the area in December 1810 during a tour of the Hawkesbury-Nepean region not long after his arrival in the Colony of New South Wales. Macquarie chose Castlereagh as one of his five towns, the others being Windsor, Richmond, Wilberforce, and Pitt Town. Castlereagh was designed to provide storage space and accommodation for the local community, especially during flood time. In his journal on 6 December 1810 Macquarie wrote ‘The township for the Evan or Nepean District I have named Castlereagh in honor of Lord Viscount Castlereagh’. A sign bearing the name Castlereagh was erected in 1811 after the streets and a town square had been marked out by the surveyor James Meehan.

Circumstances however, ensured that Penrith, not Castlereagh, became the focal point of the area and this site was never developed. The present township is located five kilometres away from Macquarie’s original site.
