Digital radio in Australia

Despite testing in Sydney and Melbourne from as early as 1999, the first genuine plan for digital broadcast radio was released in October 2005, as Helen Coonan, the then Australian Minister for Communications, Information Technology and the Arts, announced that Australia would adopt the Eureka 147 system. The Australian Government had set a launch date for digital broadcast radio in the six state capital cities, originally 1 January 2009, but this launch date was subsequently shifted back to no later than 1 July 2009[3] and the list of cities starting digital broadcast radio excluded Hobart. The peak industry body, Commercial Radio Australia, began coordinating the tests as well as organising the commercial multiplexes. The Australian Film Television and Radio School supported the development of digital radio by holding training seminars[4] and test broadcasts in various cities, organised by then Head of Radio Steve Ahern.

The major radio networks commenced a staged roll-out of commercial DAB+ services during May 2009 with Perth launching on 4 May 2009; Melbourne on 11 May 2009; Adelaide on 20 May 2009; Brisbane on 25 May 2009; and Sydney on 30 May 2009 (later delayed to 15 June due to weather conditions and kept on low power until 30 June). The roll-out of DAB+ services by the Government-owned ABC and SBS networks was delayed until 1 July 2009 due to funding delays and management issues.[5] Testing has been planned for other major cities, with a trial multiplex in Canberra commencing broadcasting on 14 July 2010,[6] and a trial multiplex running in Darwin since 13 August 2010.[7] Similar trials are being considered for Townsville and Hobart, and, as of December 2010, commercial broadcasters in regional markets have begun planning to introduce digital broadcast radio into regional population centres, possibly as soon as 2011 or 2012.[8] However, it is expected that it will be some years before digital broadcast radio is extended to the bulk of the Australian continent. Australia's vast distances and low population density are not well suited to the propagation characteristics of DAB+ and it is therefore likely that a standard other than DAB+ will be adopted for serving areas outside the major cities (leading to customer acceptance issues with receivers that can only receive one of the likely two standards).

Community digital broadcast radio services were rolled out to capital cities in late 2010 to May 2011 and were formally launched in May 2011.[9] The roll out of community digital broadcast radio services represents the largest ever infrastructure project conducted by the community broadcasting sector in Australia. The project was managed by the Community Broadcasting Association of Australia.

On 14 December 2017, the ABC and SBS services in Canberra moved to a separate multiplex (both on 9C, 206.352 MHz) providing the same services as in Adelaide, Brisbane, Melbourne, Perth and Sydney.[10] Services in Hobart began in 2019, as a national multiplex for ABC and SBS stations launched on 19 March 2018[11] and commercial multiplex launched on 3 April 2019.[12] On 23 December 2019, two commercial stations in Mandurah launched its digital service on a new multiplex 8C (199.360 MHz),[13] becoming the first market in regional Australia to have DAB services.[14]
