Scandinavian countries:
They tend to have all their populations along coastlines.
It's even more pronounced in Greenland:
Greenland has only 50,000 people and one of the lowest population densities in the world.

Australia:
Australia had almost nobody inland. The vast, vast majority avoid the harsh outback climates.
But there is a small city that has been built underground to deal with the climate:
It is called Coober Pedy.
