William Mahony (politician)

William George Mahony (1877 – 28 August 1962) was an Australian politician.

Born in Ireland, he migrated to Australia as a child and received a primary education before becoming a grocer's assistant. He became Secretary of the Grocers' Assistants' Union. In the by-election that resulted from the death of Robert Howe in 1915, Mahony was elected unopposed to the Australian House of Representatives as the Labor member for Dalley. He held the seat until 1927, when he resigned and was succeeded by the former Premier of Queensland, Ted Theodore. In 1928, a Royal Commission found that Mahony had been bribed to resign from the Parliament, probably by or for Theodore, but proof was never found. Mahony died in 1962.
