John Oliver is an Australian motorcycle speedway rider who has raced for King's Lynn Stars and Leicester Lions. Born in Brisbane, Oliver raced in Britain in 2003 for a short spell at Mildenhall then moved onto Carmarthen and Buxton, before moving to Boston the following year. After returning to Australia he rode in 2006 for King's Lynn, although his career was hampered by a broken thigh bone in early 2007. He had a successful season for King's Lynn on his return but suffered a broken collar bone in September 2008. He again returned to Australia, but joined Premier League team Leicester Lions for the 2011 season, on loan from King's Lynn, later completing a full transfer. In August 2011 he was released by Leicester, moving to Scunthorpe Saints National League team. His 2011 season was ended by a crash on his home debut at Scunthorpe in which he broke both ankles and two vertebrae. He subsequently retired from speedway.
