Never been activated to my knowledge, along with Powelltown (89.5FM) and Marysville (89.3FM) - of course this was previously active but never rebuilt after the transmitter was destroyed in the Black Saturday bushfires.
Looks like there might be some more Mallee expansion on the way - a new service for Beulah (92.1FM) has popped up in the ACMA database. Nominated site is at Willenabrina.
