Judith Anne Nunn[1] (AM) (born 13 April 1945), (also published under the pen name of Judy Bernard-Waite), is an Australian former actress, and author of both adult and children's fiction titles.

Her character became a popular cult figure in the series and Nunn continued in the role for the show's entire 1974–1977 three year run and reprised in the feature film version in 1975.

Embarking on adult fiction in the early 1990s, Judy's three novels, The Glitter Game, Centre Stage and Araluen, set respectively in the worlds of television, theatre and film, became bestsellers.

A specialist in Australian period fiction, other books she has written include Kal, Beneath the Southern Cross, Territory, Pacific, Heritage, Floodtide, Maralinga, Tiger Men in 2011, Elianne in 2013 and Spirits of the Ghan in 2015.

She married her husband, actor and writer and former Tasmanian & Royal Hong Kong police officer Bruce Venables, the same week in which she filmed her character Ailsa's marriage to Alf (Ray Meagher) in Home and Away in 1988.
