Who told you that?
Thats not correct, although they do say the earlier you have it seen tothe better.
Anyway, look up the rwh breastfeeding day stay and see if they can get you in to see Lisa Amir.
She also works at a medical clinic I think but you will need to pay (I think it cost me $30 after I got the refund from Medicare)

If you can't find the number ring the werribee mercy and ask to speak to the LC and see if they can get you some info.

Some OBs also to TT snips, Lionel Steinberg is one who does
