Answer: Timeline 3: British establish a prison colony: 160,000 people arrive. Gold is discovered more settlers arrive. The long boom: period of growth. Commonwealth of Australia established.
Step-by-step explanation:
The British Penal colony was established by Arthur Phillip in 1788. Over the next 8 decades, 160,000 more convicts were transported to Australia.
Gold is then discovered in several locations in the 1850s leading to a massive influx of settlers with the Government having to tighten immigration policies.
This preceded a long period of growth and boom called The Long Boom.
Finally in 1901, the 2 British Colonies of Australia merged to become, the Commonwealth of Australia.
