Surely you'd know kangaroos are way more plentiful now that a lot of the forests have been cleared? They sure knew a lot of stuff, but these two they didn't.
Being a hunter-gatherer meant breeding until you match the area's carrying capacity, i.e. adding any more people causes hungry deaths. Aboriginal Australians caused extinctions of quite a few species after their arrival as they were unconsciously searching for the equilibrium.

The forests were cleared before Europeans arrived using bushfires

This isn’t particular to Australia. Every land where humans appeared, megafauna vanished because they were the easiest thing to hunt and didn’t breed quickly enough.
"Fire stick farming" didn't clear that much. The most fertile lands (i.e. south east) just converted to eucalyptus sclerophyll forests that are easier to hunt in.
Either way my point about equilibrium (that means borderline hunger on average, hungry deaths every few years) stands.
