Rex Geoffrey "Tony" Williams (9 August 1928 – 19 May 2012) was an Australian politician who was a Liberal Party member of the Legislative Assembly of Western Australia from 1977 to 1989, representing the seat of Clontarf.
He attended Wesley College, and subsequently worked as a clerk.
He eventually came to run his own business, and in October 1972 was also elected to the Swan Shire Council, where he would serve until May 1978.
He was re-elected at three subsequent state elections (in 1980, 1983 and 1986),[2] and from 1983 to 1988 served as a Liberal Party whip in the Legislative Assembly.
Williams left parliament at the 1989 election, which coincided with the abolition of his seat in a redistribution.
