Australia does not discriminate against people with Hepatitis B, every case is treated individually. I suggest you consult a doctor to get a liver function panel test and also viral load. My impression is that if your Hepatitis B is inactive (with or without treatment) then it is not an issue. In any case, don't take no for an answer in your visa application.
Good luck.
I think you have heb b.i don't know if acute or chronic.you should go to a doc specialist in liver diseases then he will. Let you what to do .think more about your health first then visa
