The Southern Cross

In the past, sailors used to use Crux as a means of navigation.

The Southern Cross was used on the flag flown by miners in Ballarat, Victoria, during the rebellion known as the Eureka Stockade. The Southern Cross flag has been used as a symbol of protest in Australia since 1854.
