I got shoulder surgery done by John Salmon, and he was good, but if you have the time to wait, I'd definatley go for Greg Hoy. You'll be waiting a bit to see him but he is excellent. And yep, Simon Balster or Lynn Watson at Lifecare Prahran only treat shoulders, and Simon has treated at least 7 climbers, just that I know of.
Good luck!
