Eastick was a member of the Gawler Council from 1963 to 1972,[2][3] and served as mayor from 1968[4] to 1972. He had a second stint as mayor from 1993[5] to 2000.
Parliament
Eastick was elected to the House of Assembly for Light, based on Gawler, in 1970. Two years later, after Steele Hall resigned as LCL leader, the party elected Eastick as his successor.
Eastick led his party to the 1973 and 1975 elections, losing both to the Don Dunstan-led South Australian Branch of the Australian Labor Party. His term as leader saw the LCL, the state's main conservative party since 1932, formally rename itself as the South Australian Division of the Liberal Party of Australia, although a separate state Country Party had been reformed in 1963. He was thus the only LCL leader to have never served as Premier.
In 1996, Eastick was made a Member of the Order of Australia (AM), in recognition of his "service to the South Australian Parliament, local government and the community".[6]
