Arthur Diamond

Arthur James Diamond ( – 22 June 1906) was an Australian businessman and politician who was a member of the Legislative Assembly of Western Australia from 1901 until his death, representing the seat of South Fremantle.

Diamond was born in Derry, Ireland. He came to Australia in 1867, initially living in Victoria and then going to South Australia. Diamond settled in Adelaide, where he developed broad commercial interests, including the manufacture of jewellery. In 1878, he helped to found the Norwood Football Club, an Australian rules football club, subsequently serving as club secretary and treasurer. In 1883, Diamond served as president of the South Australian Football Association. Diamond moved to Fremantle, Western Australia, in 1886, and maintained his link with football, becoming president of the Fremantle Football Club in 1890. He was also vice-president of the West Australian Football Association in 1896.

In Fremantle, Diamond's business interests focused on his customs and shipping agency, but he also branched out into the wholesale liquor trade. He initially sat in parliament as an independent, but in 1904 joined the Ministerialist faction, which had future premier Hector Rason as its leader. He was 59. Diamond had married Ellen Louisa Goldeney in 1868, with whom he had three sons and a daughter.
