Sunfish on YMMB:
What I'm going to try next time is asking for the Western circuit, which seems to be kept a little quieter and seems to take some of the arriving traffic from the East when there is not conflicting traffic arriving from Carrum or Brighton.
This afternoon (0330Z) the controller was telling aircraft to go around on 35L twice in succession and the circuit wasn't even busy - he was just trying to get a couple of sitting aircraft away. However, I agree I wouldn't dream of going on the eastern circuit unless I had absolutely no other choice.
