In 1988 Hoyts Media, owner of Triple M Sydney, bought FM 104 and the station started using the Triple M name. The following year, the station moved from 104.1FM to 104.5FM.

In 1994, Austereo bought Triple M from Hoyts Media bringing Triple M and B105 (Hit 105) under the same ownership. This was followed in 2011 when Austereo merged with Southern Cross Media, creating Southern Cross Austereo.
