The Community Broadcasting Association of Australia (CBAA) has created a directory of community radio DAB+ stations. Some are also simulcast on AM or FM radio, others are exclusively digital stations.
At present there are more than sixty community radio services available via DAB+ across Australia which you can find using the CBAA directory link. The directory provides additional information on the type of content the station provides.
If you are outside the normal broadcast area for your favourite show or station, the relatively new Community Radio Plus app means you can still listen to the live stream.
Commercial Radio and Audio (CRA) provide a similar directory of DAB+ stations which can be found here.
