Dickinson won the Australian title in the triple jump in 1934 and 1936–37. At the 1938 Empire Games he earned bronze medals in both the long jump and triple jump, and in 1939 he won the New South Wales decathlon title. This was his last athletics competition, as the same year he enlisted in the Second Australian Imperial Force.[5][6] After World War II he worked in insurance and remained involved in athletics as an administrator. He was the chief judge of the jumping events at the 1956 Melbourne Olympics.[1][2]
After the death of Bill Roycroft on 29 May 2011, Dickinson was recognised as Australia's oldest surviving Olympian,[7][8] and as the last surviving member of the Australian 1936 Olympic team. He died on 7 October 2013, aged 98.[1][4]
