When I was haveing DD (so 4.5 years ago) there was a 'glitch' in our PHI and it was possible that we might have been paying our own way if we wanted to birth at the private. It was going to cost at least $4500 just for the hospital and $6000 if theatre was involved plus extra for anaesthetists etc. That cost did not include OB/scans/bloodtests. Don't forget you have to have an Ob if you want to birth in a private hossy too.

If you ring the finance department of the hospital they should provide you with a breakdown of costs.
