Genetic evidence can't show where your ancestors lived, but it can gesture furtively in one direction while mouthing "look over there". Even in hunter-gatherer populations, there's enough mobility that it shouldn't take anywhere near 22,000 years for African genes to make their way to Australia (or to wherever the proto-Australians were living at the time).

There's a big difference between a few people making their way over and genes achieving fixation.
