Star 106.3 (ACMA callsign: 4RGT) is a commercial Australian FM radio station based in Townsville, Queensland owned by ARN.

Star 106.3 was established as Mix FM in 1999 by RG Capital, headed by Reg Grundy.

In 2013, Prime Media Group sold its radio division to Grant Broadcasters.

In November 2021, Star 106.3, along with other stations owned by Grant Broadcasters, were acquired by the Australian Radio Network.

This deal will allow Grant's stations, including Star 106.3, to access ARN's iHeartRadio platform in regional areas.
