Why do people who live in Australia never see Polaris?

People who live in Australia can indeed see the star Polaris. They just have to visit the northern hemisphere to do it. The earth's axis has a reasonably stable orientation toward north/south; thanks to the stabilizing effect of the moon, it doesn't swing wildly out of place. So people viewing the sky from closer to the north pole can see the northern sky and not the southern sky. People viewing the sky from closer to the south pole can see the southern sky and not the northern. Polaris is very close to the point the north pole actually points to, which is why it is called 'Polaris', the pole star.

Why does the number of circumpolar constellations depend on latitude?

The number of circumpolar constellations visible from a certain latitude depends on how far north or south you are from the equator. The closer you are to the poles, the more circumpolar constellations you can see because they never set below the horizon. At the equator, there are no circumpolar constellations, as all constellations rise and set over the course of a day.

What is the earths axis point?

The north end of the earth's axis points toward a point in the sky that's a little less than 1/3 of a degree from Polaris. That's why, as close as we can tell by our eyes, Polaris appears to mark the north pole of the sky, everything else we can see appears to circle Polaris, and we call Polaris the 'North Star'. The south end of the earth's axis points to a spot in the southern sky with no comparably bright star nearby to mark it.
