Sarah - There is one doctor in Geelong that does it - His name is Mr North. I think its $125 and then a follow up visit a couple of weeks later. I think you have to have it done by 6w?
I'm still considering it, and thankfully I have my GPs appt today, so I can get a referral for it, and maybe get in in time.
Not sure if Geelong is easier for you than Melbourne.
