New South Wales 1850 badge of colony
From Stamps of the World
After the European discovery of the continent by Dutch explorers in 1606, Australia's eastern half was claimed by Great Britain in 1770 and initially settled through penal transportation to the colony of New South Wales (NSW) from 26 January 1788. The population grew steadily in subsequent decades, and by the 1850s most of the continent had been explored and an additional five self-governing crown colonies established. On 1 January 1901, the six colonies federated, forming the Commonwealth of Australia.
From 1838 the colony of NSW issued pre-printed letter-sheets and envelopes bearing the GPO badge in various values.
In 1850 the colony of NSW printed and issued its first stamps under the guidance of the postal administration and Inspector of Stamps.
For the design the GPO NSW used the Badge of Colony, this was the Royal decreed seal of Land Deeds in use at the time. It featured an image of convicts landed at Botany Bay; their convict shackles were taken off and are shown being received by Industry (allegorical figure), sitting on a bale of goods with her distaff; a spindle for the spinning of wool, a bee-hive, a pick axe, and a spade, pointing to an oxen ploughing, the rising habitations, and a church on a hill at a distance, with a fort for their defence.
Motto: Sic fortis etruria crevit (So, I think, this is how brave Etruria grew); with this inscription around the seal.
