Born in Young, New South Wales, Williams was educated at Catholic schools and then the University of Sydney, becoming a barrister in 1923.

In 1943 Williams gained Australian Labor Party (ALP) pre-selection for the Australian House of Representatives electorate of Robertson and defeated sitting United Australia Party (UAP) member Eric Spooner at the 1943 federal election.

Following the death in office of Prime Minister John Curtin on 5 July 1945, Williams urged that the caucus leadership ballot should be deferred until the return of H.V.

Williams held the seat of Robertson until the 1949 federal election, when he was defeated by Liberal Party of Australia candidate Roger Dean.
