Hi
I don't live in Brisbane.
But you could try...

Ask your Gyn if he she knew of a good Gyn who could do the surgery at the Hospital.
OR
Ask a friend about any Gyn that is good at the hospital.
OR
Ring and talk to someone in the Gyn clinic and they may bae able to tell you the name of a Gyn Surgen who specialise in this kind of surgery.

Take care
Chris
