Satya the Royal Women's Hospital in Melbourne runs a recurrent m/c clinic. I only googled it quickly and got this number from the betterhealth.vic.gov.au site and this link

I think there's one in Sydney too, and you can refer yourself to the Sydney one (don't need a GP), after 2 early m/c or 1 late loss. Not sure how you get into the Melbourne one.
