Prior to starring on television Walsh was a disc jockey on 1260 3SR Shepparton and 3XY Melbourne,[2] and a "Good Guy" on Sydney commercial radio station 2SM.
The program was renowned for introducing fellow Gold Logie winning personality Jeanne Little in 1974.
The announcement was greeted with rapturous applause and cheering, perhaps due to Martin's popularity as a 60 Minutes reporter.
[7] These include: In 1977 he purchased Richmond's Regent Theatre, then in 1982 built a twin cinema complex in Penrith.
Walsh also owns the Hayden Orpheum Picture Palace (purchased 1986), a 1935 art deco six-cinema complex in Cremorne, Sydney which he restored at a cost of $2.5 million,[7] and which features a 1925 Wurlitzer orchestral pipe organ.
In 2016 he was appointed a Member of the Order of Australia for significant service to the entertainment industry, and to the performing arts through support for young actors, theatre restoration and production.
