Thorny,
I actually agree with the problems getting through Mil airspace. I go back and forth from Sydney and Brisbane, and I get tired of spending the extra fuel to go and see scone from the air! Evans head particularly sh$ts me!!!
But it's not the controllers fault, they are operating inside the rules and framework that is set for them.
And there is quite a few planes in trees! Off the top of my head, there's a skipper, a macchi, a mirage, a Hudson, and Mdx! By no means an exhaustive list, it's been a long week and it's beer o'clock!
