[4][5] Nevinson's father Commander William Hoyes-Cock met her mother while Nancy was touring with the Entertainments National Service Association (ENSA) during World War 2.
She has also made numerous guest appearances in series including Prisoner, G.P., Police Rescue, Murder Call, Wildside, Water Rats and Packed to the Rafters and Colin from Accounts.
She post-synched female leads in cult classic Caligula (1979), Stanley Kubrick horror The Shining (1980) and James Bond film For Your Eyes Only (1981).
A hiatus from acting eventually saw Nevinson and her husband move to the Central Coast of New South Wales with their son Joss, and develop 'Amazement Farm & Fun Park' in the Yarramalong Valley, a family tourist attraction which boasted mazes, puzzles and animals.
She eventually met and married her second husband, Viv Manwaring, through whom she has three stepsons and ten step-grandchildren, and still lives on the central NSW coast.
