broadcasters, while the rest is used for commercial broadcasters. Sydney, Melbourne and Brisbane have been provided with two such multiplexes, which broadcast on frequency blocks 9A (202.928 MHz) and 9B (204.640 MHz), allowing a greater number of stations, while other cities only use a single multiplex: 8C (199.360 MHz) in Mandurah, 8D (201.072 MHz) in Canberra, 9A (202.928 MHz) in Darwin and Hobart, 9B (204.640 MHz) in Adelaide and Perth, and 9D (208.064 MHz) in Gold Coast. Commercial services on digital broadcast radio include simulcasts of both AM and FM stations, as well as new digital-only services. While most commercial radio services in Australia are provided by a small number of companies, there are no truly national commercial stations. However, since these commercial broadcasters have been given extra bandwidth on the digital platform, digital-only stations launched, including Triple M Classic Rock (Southern Cross Austereo) The Edge Digital (ARN) and NovaNation (formerly DMG), Community Radio stations with a citywide licence have reserved spectrum, equalling 2/9s of the capacity on each commercial multiplex. The Federal Government promised $10.1 million in funding to help community broadcasters with the costs of beginning digital broadcasts. During late 2010 and early 2011 most of the eligible community stations in Melbourne and several in Sydney and Brisbane began test transmissions. Melbourne's community radio stations officially launched their digital services on 14 April 2011, followed by Adelaide's community radio stations on 15 April 2011, Brisbane's on 14 May 2011, and Sydney's on 24 May 2011. Services in Perth are broadcasting in digital. Community Digital Broadcast Radio services were formally launched by Senator Stephen Conroy, Minister for Broadband, Communications and the Digital Economy on 13 May 2011 in Melbourne.
