With the outbreak of war Vincent left his job with the Australian General Electric Company and became a pilot with the Australian Air Force in England. He returned to Australia and his old job in 1945 but couldn't settle.
He tried amateur dramatics but his dialect was a mixture of Australian, Cockney, due to his stay in London, and Canadian with having mixed with Canadian forces. To correct his accent he had elocution lessons which resulted in him marrying his teacher, Doreen, and them having a daughter, Catherine.
With his diction corrected he wrote letters asking for auditions. One of these was to the Rank Organisation who replied asking him to call and see them if he was in the neighbourhood. He got a job as a stoker on a cargo ship but the journey took six months instead of the expected six weeks.
Undaunted tough he presented himself at Ranks offices where impressed with his enthusiasm they gave him a job as stand in for Donald Houston in an underwater fight with an octopus in the film The Blue Lagoon.
He then won a scholarship to RADA from where he went into rep working his way up to juvenile lead in Rain Before Seven, Barnett's Folly and Nitro. He got a few bit parts in films before moving into slightly larger parts in such as A Town Like Alice, Robbery Under Arms,and Danger Within.
He moved back to Australia in the 70's appearing in various TV series and films such as Breaker Morant, Phar Lap and Muriel's Wedding
