The History of broadcasting in Australia has been shaped for over a century by the problem of communication across long distances, coupled with a strong base in a wealthy society with a deep taste for aural communications in a silent landscape. Australia developed its own system, through its own engineers, manufacturers, retailers, newspapers, entertainment services, and news agencies. The government set up the first radio system, and business interests marginalized the hobbyists and amateurs. The Labor Party was especially interested in radio because it allowed them to bypass the newspapers, which were mostly controlled by the opposition. Both parties agreed on the need for a national system, and in 1932 set up the Australian Broadcasting Commission, as a government agency that was largely separate from political interference.
The first commercial broadcasters, originally known as "B" class stations were on the air as early as 1925. Many were sponsored by newspapers in Australia, by theatrical interests, by amateur radio enthusiasts and radio retailers, and by retailers generally. Almost all Australians were within reach of a station by 1930s, and the number of stations remained relatively stable through the post-war era. However, in the 1970s, the Labor government under Prime Minister Gough Whitlam commenced a broadcasting renaissance so that by the 1990s there were 50 different radio services available for groups based on tastes, languages, religion, or geography. The broadcasting system was largely deregulated in 1992, except that there were limits on foreign ownership and on monopolistic control. By 2000, 99 percent of Australians owned at least one television set, and averaged 20 hours a week watching it.
Australian radio hams can be traced to the early 1900s. The 1905 Wireless Telegraphy Act while acknowledging the existence of wireless telegraphy, brought all broadcasting matters in Australia under the control of the Federal Government. In 1906, the first official Morse code transmission in Australia was conducted by the Marconi Company between Queenscliff, Victoria and Devonport, Tasmania. However, it must be noted that some sources claim that there were transmissions in Australia as early as 1897 – these were either conducted solely by Professor William Henry Bragg of Adelaide University or by Prof. Bragg in conjunction with G.W. Selby of Melbourne.
