I'm not sure about this specific hospital but I'm fairly sure that if you go through the public system in a public room then there are no costs involved. most places will offer the NT scan at 12wks and the morphology scan at 20wks, you will usually get blood tests to check antibodies to german measles, HIV, Hep B etc, your blood group and your haemaglobin. Most places also do a glucose test at 26-28wks. Generally the blood tests are covered by medicare but you have to pay for the ultrasounds. hope that helps a little and that someone can give you more specific info
