You will be given the same treatment in Aus hospitals vaccinated or unvaccinated.
I would however expect you to give up your spot in line/give up your bed if you are severely ill with Covid and my little boy needs to be seen by a doctor if he falls off his bike and breaks his arm. You can’t expect him to wait in pain while you take up the doctor's time.
You would be considered a lowlife by many if you had the option of a vaccine and refused it and then expected to be ahead of people with normal illnesses when you get sick from Covid.
