Australian aboriginals are (mostly) the product of the first wave out of africa that followed the coastal route.

The second question is due to confusion over what constitutes distance. But the answer is no. There is a substantial difference from the Khoi-san and the Bantu for example because of the distance of their original areas of settlement. Khoi-San are an old population with less in and out flow. However on a PCA plot of the world it’s pretty obvious where the races sit in relation to one another.
