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. 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. Services in Hobart began in 2019, as a national multiplex for ABC and SBS stations launched on 19 March 2018 and commercial multiplex launched on 3 April 2019. On 23 December 2019, two commercial stations in Mandurah launched its digital service on a new multiplex 8C (199.360 MHz), becoming the first market in regional Australia to have DAB services. This was followed by the launch of digital radio in Gold Coast on multiplex 9D (208.064 MHz) on 4 April 2022. Current services National broadcasters The ABC and SBS operate digital broadcast radio services in all current DAB+ broadcasting markets on frequency block 9C (206.352 MHz). While most services are national, the ABC provides local ABC Local Radio stations for their respective locations. The local radio services are mostly a simulcast of their AM radio equivalents (FM in the case of Darwin); however, alternate programming is aired pre-empting most sports coverage (which is moved to digital-only station ABC Sport). This programming is also on the ABC's online streams, where sporting rights may prevent international coverage. The ABC also has a number of digital-only radio stations, including ABC Jazz, Double J, ABC Country, and special-events station ABC Extra, which is used to provide additional coverage for special events which may otherwise not be able to be covered. Commercial and community radio Each region with access to digital broadcast radio has a number of multiplexes set aside for commercial and community radio services. In these multiplexes, two-ninths of the bandwidth are reserved for community
