I was told that there are 4 ways to find the south celestial pole (SCP):
1. Where the right bisector of the pointers meets the extended long axis of the southern cross is the SCP;
2. extend the long axis of the southern cross 3+1/2 times its own length and that spot is the SCP;
3. find both magellanic clouds and create an imaginary 3rd point of an equilateral triangle, which will be a SCP;
4. use canopus and achenar as two corners of an equilateral triangle and the 3rd (imaginary point is the SCP)
When I lived at Ayers Rock the southern cross seemed to disappear below the horizon sometimes and you could use one of the other methods
