Auburn (NSW), NSW
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Auburn is a multicultural suburb of Western Sydney, about 16 kilometres west of the central business district, today part of Cumberland City Council. The Wangal clan are recognised among the original inhabitants of the district; the celebrated colonial-era figures Bennelong and his wife Barangaroo were both Wangal people. In February 1793 the surrounding area became one of the colony's first free-settler farming districts, granted to a small group that included Quaker families and known as Liberty Plains — a proud heritage still echoed in the local motto, 'Liberty, with steady zeal'. The township itself was surveyed in the late 1870s and named Auburn after Oliver Goldsmith's poem 'The Deserted Village', which opens 'Sweet Auburn! Loveliest village of the plain'. Successive waves of migration have since made Auburn one of Sydney's most diverse suburbs, home to the landmark Auburn Botanical Gardens and the Turkish-built Gallipoli Mosque.
