How much does it cost to see a doctor?

I don't have any insurance or medi care as I am on a tourist visa in Australia. I've always had chronic eczema and it has been getting worse since I've arrived here. I am running out of my ointment brought from my country and any ointment purchased from a local pharmacy doesn't work for me, so I need to see a doctor to get a prescribed strong cream. How much would it be to see a doctor here in Melbourne without insurance? Thanks in advance.
