Austral is a suburb of Sydney, in the state of New South Wales, Australia. It is 42 kilometres south-west of the Sydney central business district, in the local government area of the City of Liverpool.

The area that now constitutes the suburbs of Austral was a parcel of land in West Hoxton purchased by the Austral Banking and Land Proprietary. When residents pushed for a second public school in the Hoxton Park area in 1891, Austral Banking and Land Proprietary donated 3 acres (12,000 m) of its land for the site and, in return, the school was named Austral Public School. The name of the school became synonymous with the area although it wasn't officially recognised until 1972. Austral Post Office opened on 7 February 1894.

It is bounded to the west by waterway Kemps Creek, to the east by a Sydney Water supply channel, to the north by a straight division, and to the south by Bringelly Road. Bonds Creek flows southeast–northwest through the suburb, and converges with Kemps Creek near Fifteenth Avenue. It is of note in its design, its streets laid out in a grid pattern, and all horizontal ones named 'Avenue', in numbers from south to north increasing. It is part of the Rural–urban fringe of Western Sydney that runs from Horsley Park through Badgerys Creek, the adjacent Rossmore, Austral and down to Catherine Field.
