Ok, this seems to vary wildly from place to place.
In Darwin, we paid to have it done at the Hospital
In Richmond NSW, we would have paid to have it done thru a private pathology service
In Sale VIC, it was free through the hospital
Here in Canberra, it appears I will have to pay to have it done thru a private pathology service. They charge whatever they want to here (>$300 for a pelvic ultrasound last year when I thought I had a cyst) as there are not enough Providers to keep the charges down! (Also in Canberra they all think they are a little Sydney hahaha).
*Sigh* So needless to say we are 100% likely to hit the safety net this year!!!
