Do they have an email address you can book in by? My hospital was hard to get through to as well but I rang a few times to listen to the message to get the email address written down and on my fourth call I got lucky and they picked up. You could try looking up the hospital on the net you may find info on there - there's stacks of info on my hospital on the net. I was able to book myself in as I can't see my OB until I'm 14 weeks (already have my referrals for scans & BT's from an OB that works from a different hospital). I'm being handled by a GP at a bulk billing clinic until then so it costs nothing except if I go after 6pm or on weekends which costs $10.
