Digital radio in Australia#Canberra

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{{cite web|url=http://www.dbcde.gov.au/media_broadcasting/radio/digital_radio/rollout_of_digital_radio_in_australia|access-date=20 May 2009|url-status=dead|archive-url=https://web.archive.org/web/20090522202307/http://www.dbcde.gov.au/media_broadcasting/radio/digital_radio/rollout_of_digital_radio_in_australia|archive-date=22 May 2009|title=Rollout of digital radio in Australia | Department of Broadband, Communications and the Digital Economy }} - redirects to http://www.communications.gov.au/, the home page of the Department of Communications. 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{{Cite web|url=https://www.radioinfo.com.au/news/first-adelaide-digital-radio-broadcast|title=First Adelaide Digital Radio Broadcast|last=Radioinfo.com.au|date=19 June 2007|website=Radioinfo}} 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.[http://www.abc.net.au/rn/breakfast/stories/2009/2569954.htm Tech review with Peter Marks: digital radio], 14 May 2009, ABC Radio National Testing has been planned for other major cities, with a trial multiplex in Canberra commencing broadcasting on 14 July 2010,{{cite web|title=Digital radio trial to begin in Canberra|date=2010-05-05|url=http://www.digitalradioplus.com.au/index.cfm?page_id=1013&display_news_id_1104=1047|access-date=2010-05-05|archive-url=https://web.archive.org/web/20110220070946/http://www.digitalradioplus.com.au/index.cfm?page_id=1013&display_news_id_1104=1047|archive-date=20 February 2011|url-status=dead}} and a trial multiplex running in Darwin since 13 August 2010.{{cite web|title=Digital radio trial on in Darwin|date=2010-08-13|url=http://www.digitalradioplus.com.au/index.cfm?page_id=1048&display_news_id=1060|access-date=2010-08-13|archive-url=https://web.archive.org/web/20100902174459/http://www.digitalradioplus.com.au/index.cfm?page_id=1048&display_news_id=1060|archive-date=2 September 2010|url-status=dead}} 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.{{cite web|title=Regional radio broadcasters meet to discuss rollout of digital radio|date=8 December 2010|url=http://www.digitalradioplus.com.au/files/uploaded/file/Media/Regional%20Broadcaster%20Meeting8Dec2010.pdf|access-date=2010-12-19|work=Media release|publisher=Commercial Radio Australia (CRA)|archive-url=https://web.archive.org/web/20101214222203/http://digitalradioplus.com.au/files/uploaded/file/Media/Regional%20Broadcaster%20Meeting8Dec2010.pdf|archive-date=14 December 2010|url-status=dead}} 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.{{cite web|title=National Community Launch|date=23 May 2011|first=Alex|last=White|publisher=Community Digital Radio|url=http://digital.radius.org.au/news/national-community-launch-0|access-date=3 November 2011|archive-url=https://web.archive.org/web/20110830192304/http://digital.radius.org.au/news/national-community-launch-0|archive-date=30 August 2011|url-status=dead}} 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.{{cite web|title=New DAB+ stations in Canberra & Darwin|url=http://www.digitalradioplus.com.au/latest-news/2017-(1)/new-dab-stations-in-canberra-darwin}} Services in Hobart began in 2019, as a national multiplex for ABC and SBS stations launched on 19 March 2018{{cite web|title=ABC and SBS launch DAB+ services in Hobart|date=17 March 2018 |url=https://www.radioinfo.com.au/news/abc-and-sbs-launch-dab-services-hobart}} and commercial multiplex launched on 3 April 2019.{{cite web|title=Digital radio switches on in Hobart|url=http://www.digitalradioplus.com.au/latest-news/2019-(1)/digital-radio-switches-on-in-hobart}}

On 23 December 2019, two commercial stations in Mandurah launched its digital service on a new multiplex 8C (199.360 MHz),{{cite web|title=Radiocommunications (Foundation Category 1 Digital Radio Multiplex Transmitter Licence - Mandurah) Declaration 2019 (No.1)|url=https://www.acma.gov.au/sites/default/files/2019-11/Radiocommunications%20Foundation%20Category%201%20Digital%20Radio%20Multiplex%20Transmitter%20Licence%20%20Mandurah%20Decl.pdf}} becoming the first market in regional Australia to have DAB services.{{cite web|title=Mandurah gets DAB+ for Christmas|url=https://www.digitalradioplus.com.au/latest-news/2019-(1)/mandurah-gets-dab-for-christmas}} This was followed by the launch of digital radio in Gold Coast on multiplex 9D (208.064 MHz){{cite web|title=Radiocommunications (Digital Radio Channels – Queensland) Plan Variation 2020 (No. 1)|date=14 December 2020 |url=https://www.legislation.gov.au/Details/F2020L01604}} on 4 April 2022.{{cite web|title=DAB+ radio set to launch on the Gold Coast|url=https://www.digitalradioplus.com.au/latest-news/2022/dab-radio-set-to-launch-on-the-gold-coast}}

The ABC and SBS operate digital broadcast radio services in all current DAB+ broadcasting markets on frequency block 9C (206.352 MHz).[http://www.acma.gov.au/WEB/STANDARD/pc=PC_9150 List of licensed broadcasting transmitters] {{webarchive|url=https://web.archive.org/web/20120625123103/http://www.acma.gov.au/WEB/STANDARD/pc%3DPC_9150 |date=25 June 2012 }}, Australian Communications and Media Authority (ACMA) 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,[https://archive.today/20120915071122/http://www.theaustralian.news.com.au/story/0,,25718225-7582,00.html ABC launches digital radio stations], The Australian, 1 July 2009{{dead link|date=April 2014}} including ABC Jazz,[http://abcjazz.net.au/ Home page], ABC Jazz Double J,[http://doublej.net.au/ Home page], ABC Dig Music ABC Country,[http://abccountry.net.au/ Home page] {{Webarchive|url=https://web.archive.org/web/20140327144452/http://abccountry.net.au/ |date=27 March 2014 }}, ABC Country and special-events station ABC Extra,[http://www.abc.net.au/radio/digital/extra/ Home page], ABC Extra which is used to provide additional coverage for special events which may otherwise not be able to be covered.

Because the Australian Government chose to give the number of DAB channels (and hence revenue) priority over technical and quality factors, the bitrates available per channel are very low by international standards. The audio quality of Australian DAB is correspondingly low - only 80 kbps for ClassicFM, for example, and most channels have much lower bitrates than this. So DAB is in general well below the 128 kbps traditionally accepted as CD quality, and an interference-free FM broadcast will almost certainly provide better audio.{{dubious|Questionable paragraph re: bitrates of national services, left for discussion|date=July 2024}}

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 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.{{cite web|url=http://www.cbaa.org.au/content/Digital-Radio-A-Go-Go|access-date=23 February 2010|url-status=dead|archive-url=https://web.archive.org/web/20100309074107/http://www.cbaa.org.au/content/Digital-Radio-A-Go-Go|archive-date=9 March 2010|title=Digital Radio a Go-Go | Community Broadcasting Association of Australia }} 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.
