Corke began her career with a minor role in the film 'I Live with Me Dad'. She then had a role in Prisoner Cell Block H in 1986, and after that she joined the cast of Neighbours, playing Gail Lewis/Robinson from 1987 to 1989.
After she returned for a cameo appearance as Gail in Neighbours in 2005, Corke returned for guest appearances in 2006 and 2007.
In 2007 Corke appeared in an episode of City Homicide.
Corke met her husband Nick Carrafa while they were both appearing on Neighbours in 1987. The couple did not go public with their relationship until he left the show in 1988, fearing their real-life romance would confuse viewers.
Corke is a well-known animal activist and campaigner for the prevention of cruelty to animals.
