Let $O$ be a celestial observer situated at the surface of Earth in the Southern hemisphere.

Let $OQ$ be a straight line parallel to Earth's axis.

Let $Q$ be the point in the visible hemisphere at which $OQ$ meets the celestial sphere.


Then $Q$ is the south celestial pole.


That is, the south celestial pole is the pole of the celestial equator which is the zenith of the South Pole.
