I was just wondering if anyone could share with me how much, approx, ultrasounds cost at each visit?

I am just trying to get an idea of how much having a bub will cost us. We are going to go private. So if anyone has any other useful info that they wouldn't mind sharing, it would be appreciated.

Thanks,
Nadine.

P.S Has anyone used/using RPA in Sydney? If so how do you find it?
