1819 in Australia
- Monarch - George III
John Thomas Bigge was appointed a special commissioner to examine the government of the Colony of New South Wales by Lord Bathurst. His brief was to determine how far the expanding colony of New South Wales could be "made adequate to the Objects of its original Institution", which were understood to be purely to be a penal colony. He was to come to Australia to investigate all aspects of the colonial government, then under the governorship of Lachlan Macquarie, including finances, the church and the judiciary, and the convict system.
