Hello, I'd like to learn more about Sydney
Sydney is a city on the east coast of Australia, which is the capital of New South Wales. About 5 million people live there which makes it the biggest city in Oceania. Sydney was started in 1788. Captain Arthur Phillip brought the First Fleet to settle in Australia. The settlers were mostly convicts from crowded prisons in England and Ireland, with a group of soldiers to guard them.
I knew that about the convicts, how crazy is that?! Can you tell me about the history a little more?
Enlightened for his age, Captain Arthur Phillip's personal intent was to establish harmonious relations with local Aboriginal people and try to reform as well as discipline the convicts of the colony.In 1804, Irish convicts led the Castle Hill Rebellion, a rebellion by convicts against colonial authority in the Castle Hill area of the Bristish colony of New South Wales.
I didn't know that, that's interesting! Any other awesome history facts?
The Rum Rebellion of 1808 was the only successful armed takeover of government in Australian history, where the Governor of New South Wales, William Bligh, was ousted by the New South Wales Corps under the command of Major George Johnston, who led the rebellion.
What do you know about the Urban Structure?
Public housing in Sydney is managed by the Government of New South Wales.
Anything else you are willing to share?
Suburbs with large concentrations of public housing include Claymore, Macquarie Fields, Waterloo, and Mount Druitt.
Thank you for all the information! You have been really helpful!
You're welcome!
