Television broadcasting in Australia

Television broadcasting in Australia began officially on 16 September 1956, with the opening of TCN-9, quickly followed by national and commercial stations in Sydney and Melbourne, all these being in 625-line black and white. The commencement date was designed so as to provide coverage of the Olympic Games in Melbourne. It has now grown to be a nationwide system that includes a broad range of public, commercial, community, subscription, narrowcast, and amateur stations.

Colour television in the PAL 625-line format was introduced in 1967 and went to a full-time basis on 1 March 1975 while subscription television, on the Galaxy platform, began in January 1995. Digital terrestrial television was introduced on 1 January 2001 in Australia's five largest capital cities.

As early as 1929, two Melbourne commercial radio stations, 3UZ and 3DB were conducting experimental mechanical television broadcasts – these were conducted in the early hours of the morning, after the stations had officially closed down. In 1934, Dr Val McDowall at amateur station 4CM Brisbane conducted experiments in electronic television.
