The Stars on the Australian Banner represent the Southern Cross, a constellation that is visible only in the Southern Hemisphere. If I am not mistaken, the related country of New Zealand ( for many years their armed forces were combined the ANZACS) has the motto of Heaven"s Light Our Guide! This refers to the constellation with added religious connotations.
The star is known as the Commonwealth Star, or the Federation star.
