The Australian Federation Flag, also known as the New South Wales Ensign, was the result of an attempt in the 1830s to create a national flag for Australia, which was divided at the time into several British colonies. Captain , Harbour Master of Port Jackson (Sydney), proposed the flag in 1831 in The NSW Calendar and Post Office Gazette; Gronow also designed the flag, which was based on the Colonial Flag of 1823. The Eureka Flag, flown by rebels at the Eureka Stockade in 1854, was reportedly influenced by designs such as the Federation flag.
