Price was born in Everton in Liverpool, England, the son of Thomas Price, the future first Labor Premier of South Australia, and his wife Anne Elizabeth (née Lloyd). His family migrated to South Australia in March 1883 and settled at Hawthorn, where Price was educated at Mitcham Public School, Unley Public School, the Adelaide Business College and the South Australian School of Mines. He worked in the clerical branch of the state railways from June 1898 until his election to the House of Assembly in 1915. He volunteered for service in World War I along with several brothers, but was rejected.[1][2][3][4]
He was secretary of the Railway Officers' Association and the state branch of the Federated Masters' and Engineers' Association, president of the South Australian Government General Workers' Association and the Port Adelaide Trades and Labour Council, and later president of the United Trades and Labour Council and state president of the Labor Party.[1][5][3][4] He was both a councillor and alderman of the City of Port Adelaide, serving from 1916 to 1924, and was president of the Largs Bay Progressive Association.[6][1]
In 1928, he was elected to the Australian House of Representatives as the Labor member for Boothby, defeating sitting NationalistJack Duncan-Hughes. He was secretary to the parliamentary Labor Party from 1929, but left the Labor Party in the 1931 Labor split, in which several Labor MPs merged with the Nationalists to form the United Australia Party under the leadership of Joseph Lyons. He later served as secretary to the parliamentary United Australia Party and Government Whip from 1940 until his death.[1][11]
He died in office in 1941 at the age of 59; he had "not been in robust health" for two years, but his death was sudden and unexpected.[12][13] His death raised serious concerns that the Menzies government could fall if his seat were lost in a by-election. However, UAP candidate Grenfell Price held the seat in the resulting by-election, although the government subsequently fell in August anyway.[14][15]
