Television broadcasting in Australia
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〔https://www.racp.edu.au/page/library/college-roll/college-roll-detail&id=496〕 at amateur station 4CM Brisbane〔https://espace.library.uq.edu.au/view/UQ:212637/s00855804_1961_1962_6_4_750.pdf,〕 conducted experiments in electronic television.
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 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.

Australia has three national public broadcasters, the Australian Broadcasting Corporation, the Special Broadcasting Service, as well as more recently, National Indigenous Television..
