Normally, Aboriginal groups were easily able to find enough food for their entire clan in three or four hours of hunting and gathering each day. They know which fruit and animals are available at certain times, how to gather or hunt successfully and how to store foods.

There are still aboriginal people alive today that gather fod in the traditional manner - when I was 20 or so the Pintupi Nine wandered in, some stayed a few left and returned to the desert. https://www.bbc.com/news/magazine-30500591 There are still many people living hybrid lives, using modern metals and traditional knowledge to gather food, eg: https://www.youtube.com/watch?v=7gmCX7R-W4c A key point here is 30+ thousand years of getting to know and shaping the landscape - promoting plants and animals over others, learning the movements and habits of animals, seasons of plants, not having closed in winters, etc. |
my guess is that you probably picked a particular sparsely living group in particular favorable climate that eventually probably got wiped out by a hungrier group.
furthermore, hunting for three hours no freaking way can sustain population density of say Indonesia, or some other Asian countries which have been populous for many centuries.
