Thanks for the info.
I'm going with Dr Parkinson out of St Vincents. Was also recommended Dr Pope in North Sydney but he was too hard to get in with. Could have gotten in sooner for cheaper with a less recommended Dr, but i don't want to mess around with my back - Dr Pope and Dr Parkinson were both highly recommended by a few trusted people I spoke to.
Surgery is happening next month. Just got my quote this morning so yeah, i'm looking at about the same out of pocket (also private - glad i'm not paying that hospital bill).
Fortunately, lost wages won't be an issue for me - I'm permanent staff so work will cover the time off as sick leave. boss said take til easter unless something urgent comes up. good news.
