Over 162,000 prisoners were sent from England to Australia between 1788 and 1850. The first 11 of 806 ships to carry these men was called the First Fleet. Most of the people on board were British, but there were also some French, American and African. These people are now regarded as the founders of Australia. Aboriginals had inhabited the country for 10,000 years before Europeans arrived.
