The Penthouse Club was an Australian weekly variety program produced live to air from the studios of HSV-7 Melbourne from 10 October 1970.
The program, screening each Saturday night from around 8.30 pm (the starting time varied over the years depending on HSV-7's Saturday night VFL football commitments), was a mix of comedy, light entertainment and live coverage of harness racing from the RAS Showgrounds and, later, Moonee Valley racecourse.
The Penthouse Club was considered a welcome alternative on Saturday nights which is often regarded as a wasteland of reruns and low-grade movies on other channels.
In 1978, Williamson was replaced by Ernie Sigley and the program was retitled Saturday Night Live (with no relation to the NBC show) in 1979.
Also during the 1970s, Network Ten's Adelaide station ADS-7 produced their own version of The Penthouse Club with Bob Francis, Anne Wills and Sandy Roberts, with the program and presenters winning a number of Logie Awards for popularity in South Australia.
