Why did Britain officially stop using Australia as a penal colony in 1868?
When the last shipment of convicts disembarked in Western Australia in 1868, the total number of transported convicts stood at around 162,000 men and women. They were transported here on 806 ships. The transportation of convicts to Australia ended at a time when the colonies’ population stood at around one million, compared to 30,000 in 1821. By the mid-1800s there were enough people here to take on the work, and enough people who needed the work. The colonies could therefore sustain themselves and continue to grow. The convicts had served their purpose.
