An interesting question posted in the “Hourly Music Logs” thread:
It’s because of the fact that neither DMG nor RG Capital have ever owned a commercial radio licence in Wollongong. In fact, when ACE Radio was selling off Wave FM back in 1995, Sea FM Ltd (later RG Capital) was one of the potential buyers of the station. Here’s an SMH article from that time: Link
Also, WIN has owned 2OO, later i98, since 1987.
That said, if either WIN were to sell off i98, or Grant were to sell off Wave FM, then I could definitely see SCA entering the Wollongong radio market. The question is what format one of the stations would take, especially if they only own one station in the market.
