Here's one I have all my CPL students at Redcliffe do:
YRED GALLANGOWAN (approx YGYM 234 degrees 22nm) sunny Glen (YBSU 311 degrees 68nm then YBSU with a full stop, YRED. It's a tough Nav but very much CPL standard.
As for getting a clearance through the Brisbane TMA, yes it can be done and I would expect a CPL candidate to be able to do it.
