If you are currently a subsidised patient and choose an A1 ward for your admission, the admission will typically be automatically treated as a private-class admission and you will pay A1/private ward rates.. There is no switching needed before that you can choose at the admission time.
There is no government subsidy for A1 as it is private class. Final cash paid depends on whether it is normal or c section and whether you have medi-save or not . Normal can be 8 to 12k and c section can be 12 to 18k before medi-save
