I was in Griffith a month ago, and according to the local paper there were two unnamed operators sniffing about the place looking at running a YGTH-YMML service, following failed negotiations between the council and another "operator" who proposed to run a service with imaginary Beech 1900s.
Apparently one of the two was Brindabella, but no idea about the other; given Rex got rid of their YGTH-YMML service last year, I doubt it'd be them.
What are the chances this mystery operator, who's apparently in the market to pick up some very thin regional routes like YGTH-YMML would also be looking at some of Brindabella's routes?
