Australia has had three National flags, six Royal Navy Flags, including the Chief of Navy flag that has been used since 1920 and many others.
This was the original Union Flag introduced in 1606 that did not include the Saint Patrick's Saltire, included from 1801 after the Acts of Union 1801. The first such attempt was the National Colonial Flag created in 18231824 by Captains John Nicholson and John Bingle. The most popular "national" flag of the period was the 1831 Federation Flag, also designed by Nicholson. These flags, and many others such as the Eureka Flag (which came into use at the Eureka Stockade in 1854), featured stars representing the Southern Cross.
