Why is the southern cross on the Australian flag?
The Southern Cross was an important navigational benchmark for sailors. It guided them through the relatively unknown waters around Terra Australis Incognita (the unknown south land) and was not visible in the northern hemisphere from whence the sailors came. The Southern Cross simply became synonymous with Australia.Also, the Southern Cross was a symbol of independence and a fair go, freedom and democracy, in the Eureka Stockade. This makes it important to Australia and its people.According to the Australian National Flag Association, the primary purpose of the Southern Cross is to represent our geographic position in the Southern Hemisphere.
