Just had a look on the CFS website, which tells you what you can or can't do,most parks and government reserves you can't have a fire during the ban season, but it is interesting some areas you are allowed a campfire without a permit during the fire ban season as below (not on total fire ban days)
Can I have a campfire? YES
Providing:
the fire is in a 30 cm deep trench and no more than one square metre in area;
you have a four-metre cleared space around and above the fire;
a responsible person is in attendance at all times with water and/or an extinguisher
NO Unless you have a Schedule 10 permit from your local council.
