Potts Hill, New South Wales

Potts Hill, a suburb of local government area City of Bankstown, is 21 kilometres south-west of the Sydney central business district, in the state of New South Wales, Australia. It is a part of the South-western Sydney region.

Potts Hill also shares its postcode of 2143 with neighbouring Regents Park and Birrong.

Much of the area of Potts Hill is occupied by the Potts Hill Reservoir owned and operated by Sydney Water.

History
Potts Hill is named for Joseph Hyde Potts, an accountant in the Bank of New South Wales, who received a grant of 1100 acre in 1833. He originally called his property Hyde Park and had increased his holdings to 2564 acre by 1835. Two reservoirs were built here between 1888 and 1923 as part of the Sydney water supply system.

Potts Hill migrant camp
In 1946 the Sydney Water Board (now Sydney Water) started to build the City Water Tunnel — a water supply tunnel from Potts Hill to Waterloo in Sydney to supplement the existing Pressure Tunnel. Workers camps were set up at Potts Hill to accommodate the European migrant workers who were indentured from the many displaced persons brought to Australia after WWII. Due to the proximity of Regents Park, the camp was also known as the Regents Park migrant camp.

Conditions at the Potts Hill camp were primitive. Known as "tent city", many workers had to live in tents, some of the huts were in bad repair and there was a lack of hot water, showers and electric coppers. In early 1951 there were nearly 1,000 men living in the camp. The local businessman who sold food to the workers neglected to install refrigeration and had a poor record for hygiene. Workers' wives were only allowed in the camp between ll am. and 5 pm. on Sundays. The men had to rent rooms at week-ends, to be with their wives. The workers also experienced hostility form the union members of the Water Board.

Potts Hill radio astronomy field station
In 1948 the Division of Radiophysics of the CSIRO obtained permission from the Water Board to operate a field station on vacant land adjacent to the Potts Hill reservoir. The southern and eastern sides of the No. 1 reservoir were used for the east-west and north-south arms of the solar grating arrays. By 1952 it had become the Division's largest field station. Equipment included a 4 element yagi and single yagi antennas, a 16-ft x 18-ft paraboloid, a Mills Cross Telescope prototype, a 68-inch paraboloid, swept lobe interferometer yagi aerials, a prototype of a Fleurs Cross aerial and 16 and 32 element solar grating arrays. Radiophysics continued operations until 1962 when the field station's operations were transferred to other field stations.
