I was just up your way last week rode from Gold Coast to Gladstone and then back to Bundy to stay the night. Off to Harvey Bay and Maryborough to do installs. Then rode to Chinchilla for a meeting and then through Dalby, Toowoomba and home to the Gold Coast.
I dont know your area that well but the ride from Bundy to Gympie then back to Childers using the A3 look like a really nice ride. Next time Im back will let you know and see if we can have a ride.
