i have been using queen mary's private clinic and have a booking there. am also seeing dr ghosh (primarily) and am on waitlist for matilda. i am a hi risk case, so i have to deliver at qm if i don't make it to 34 weeks. i have found the cost for qm private clinic to be about the same as ghosh for doctor visits, sonograms, etc. the waiting time has been very reasonable (even better than for dr ghosh, though his office is good about calling day-of to let you know how long he is running behind). have not been through the delivery yet but i expect costs would be similar. frankly, i am torn between queen mary and matilda because of the excellent nicu, etc at qm. if my booking does not come through at matilda, i am fine with that. the main difference that i can ascertain is that the food is much better at matilda but we will work around that with food deliveries, etc!
