RTRFM is more than radio. Much, much more.

Since its inception in 1977, our station has promoted local artists, provided a platform for diverse voices and diverse views, supported local businesses and been part of the social fabric in WA.

We are proud to provide an independent voice to artists, play different music and relate local stories with our own brand of unplaylisted, hand-crafted, homegrown radio.

And we want to keep being The Sound Alternative for years to come - but we need your help.

One third of our annual income ($350,000) is raised right now during Radiothon. You – our listeners – are our main funders. Your support is what keeps the station going year after year.
