I was offered a water birth a Blacktown Hospital through the midwives clinic but ended up needing medical intervention.

I had a water birth at Westmead public in April, they definately support it and the facilities are lovely and new!!
They have baths and they do "unofficial" waterbirths, but it's not the policy of the hospital and it would be unfair to suggest that it's a possibility when really it depends who's on duty and who's not on duty. Blacktown hospital no longer offer waterbirths
