Southern Cross Austereo traces its origins to Austereo, which acquired the licence for metropolitan Adelaide when commercial FM broadcasting was introduced in Australia. A Macquarie Bank radio vehicle assembled to acquire regional stations bought Southern Cross Broadcasting and was renamed Southern Cross Media Group, before merging with Austereo to form Southern Cross Austereo. It broadcasts nationally through the Hit Network and Triple M radio brands alongside the LiSTNR digital audio platform.
It operates radio stations serving metropolitan and regional communities in every Australian state through local content and news. Its free LiSTNR app gathers radio, podcasts, music and sport in a single Australian-focused destination, positioned against global open audio platforms that offer neither granular local news nor live radio. It sells advertisers access to those audiences across broadcast and digital audio.
