The number of DAB+ digital radios in Australia climbed to 3.8 million in 2017, up 24% over the past 12 months, according to figures released by radio industry body Commercial Radio Australia.
The number of DAB+ portable and home radio receivers in market totalled 2.37 million at the end of the calendar year, with another 1.42 million in cars.
CRA chief executive officer Joan Warner said the large increase in DAB+ devices was expected to continue in 2018, with digital radio now standard in 47% of all new vehicles being sold.
“More than 560,000 of the new cars sold in 2017 were fitted with DAB+ radio.
“The adoption in cars is ahead of forecast, which is great news as it means more listeners are able to discover digital radio and the new digital-only stations on offer,” she said.
Ms Warner said 43% of listeners in the five major capitals of Sydney, Melbourne, Brisbane, Adelaide and Perth now have access to DAB+ digital radio at home, at work or in the car.
Permanent digital radio services are being switched on in Canberra, Darwin and Hobart this year.
Commercial radio broadcasters have identified another 13 regional centres as priority markets for rollout within the next five years, including Newcastle, Dubbo, Goulburn and Albury.
Ms Warner said broadcasters are working with the Australian Communications and Media Authority and the Department of Communications on planning and regulatory processes.
