Corke developed a strong interest in the media in his youth. Corke was one of many radio personalities to be approached to work for Melbourne's new television station, GTV-9. During the test broadcast, Corke broadcast live from a temporary studio at the transmitter site on
Mount Dandenong where he introduced selected programs including a
John Wayne film and a
Terrytoons cartoon. Corke was selected as one of the on air comperes on the night GTV-9 was officially opened on 19 January 1957. After Victorian governor
Sir Dallas Brooks had officially opened the station, Corke and Terry Dear compered the evening's variety entertainment. From the program's inception in 1957 until 1959, Corke was a regular on GTV-9's variety show
In Melbourne Tonight, where he appeared as an offsider to host
Graham Kennedy. Corke left
In Melbourne Tonight in 1959 upon the arrival of
Bert Newton who formed a successful on air partnership with Kennedy. Following his departure from
IMT, Corke replaced
Happy Hammond on the children's program
The Tarax Show where he became known as "King Corkie, King of the Kids". In 1959, Corke co-hosted the weekly daytime variety show
Geoff and Judy. The following year, he hosted
Football for the Ladies, a program GTV-9 produced for female fans of
Australian rules football. Other programs Corke was involved with at GTV-9 included
Anything Goes,
Penalty Box, and
Happy Go Lucky. ==Personal life and death==
