When RAAus and GA play nicely together the world will be a better place an optimist would say!
Perhaps RAAus can stay below 5,000ft and GA above and GA use left circuit and RAAus use the right and everyone will be happy. Perfect solution. I haven't worked out the bit where GA get to above 5,000ft though.
