River 94.9 (callsign: 4MIX) is a commercial radio station that broadcasts to South-East Queensland. The station opened in February 1990, and was formerly known as Star 106.9, which used to operate on the frequency now occupied by Nova 106.9. The station was previously owned by Rural Press & Bundaberg Broadcasters, forming part of the Star Broadcasting Network, followed by Grant Broadcasters. History As QFM From its launch until 1997, QFM broadcast contemporary hit music format. As Star 106.9 In 1997, QFM rebranded as Star 106.9, dropping a CHR format for a classic hits format.
