There's only two birthing centres in Vic (what I learnt on Thursday!), Monash and the Angliss (both public - yay). There used to be 6 Apparantly Box Hill have the best spas. Interestingly the Mercy have apparantly been trying to get waterbirths 'allowed' for the last 10 years to no avail. Anyway, sorry that none of this info helps you.

Perhaps get your DH to read up on homebirths (only .2% of bubs are home births - another Thursday fact!).
