In the southern hemisphere, we don't have one star to point to South - we have 2. Near the "Southern Cross" constellation are our 2 bright indicators (I can't remember their names, but in the southern hemisphere, they are very obvious) - draw a line between the 2, then draw a perpendicular line at the half-way point of the line - it points directly south!

They may point directly towards the southern celestial pole, but this is not much use, because unless you know how far along this line to go, it doesn't give you any indication where it is.
