Hello to everyone on this forum.

I am new to medicare.I am not a permanent resident yet but has applied already for residency and recently got medicare card.
I am eight weeks pregnant.for some reasons my doctors asked for pregnancy viability ultrasound.Its really ripping off expensive costing me 200$ and medicare rebate is just 51$.
Is there any way I can get ultra sound from Public hospital? I am already booked for 12th week ultra sound which is again costing me 210$.
Your advices are very welcome.
Thanks
Nim
