Two things to note when looking at that list: 1. Bushfires may be more frequent in some parts of Australia than others. So two bushfires of equal size, but occuring in different regions, may not necessarily be equally common. 2. The list on Wikipedia is referring to final surface burned, after the fire is contained, or has burned out. However the 1.5M Acre figure mentioned here seems to be only the current surface burned - presumably it will continue to expand and burn more.
