there’s 3 formats on the adult side - with more possibilities to come in the future:
Townsville - “Greatest Hits from the 70s to Now”
Gold Coast - “Greatest Hits from the 80s to Now”
Toowoomba - “Classic Hits from the 60s, 70s and 80s”
Depending on the demographics the station can pick which format it runs. All are a really looking to minimise the spillage to the Hit stations, but there are some adults who still like Rihanna alongside of Springsteen, so you have to also think of them.
