Seems its run by Transport QLD.
Maritime Safety Queensland and the Department of Transport and Main Roads are still run by humans. Just give them a ring. I am sure you will find them quite helpful.
Bowen Harbour has marina berths, pile berths and in the side basin has or used to have fore and aft mooring berths.
Yes I do have first hand knowledge of Bowen Harbour but it was in 1995. Prices may have changed but I think the infrastructure is about the same. Unless the financially failed marina developments at Airlie Beach have drastically reduced their prices I am sure Bowen Harbour will be the most economical place to desert your yacht.
Of one thing I am absolutely sure and that is if a cyclone hits your yacht will be safer in Bowen than Airlie Beach.
I hope that info helps your decision making.
