It is owned by Great Southern Land Media Group, and is sister station to 92.7 Mix FM.

Modelled on its Gold Coast sister station, 91.9 Sea FM was launched on 26 June 1996.

Following the merger with Austereo, in 2013 the Australian Communications & Media Authority deemed that Southern Cross Austereo's ownership of stations in both the Brisbane and Sunshine Coast markets breached media diversity laws.
