Australia's first police force was a band of 12 of the most
well behaved Convicts.
The First Fleet arrived in New South Wales in January 1788, with a contingent of naval officers and men as well as their cargo of convicts. At first, the Marines of the Royal Navy were responsible for keeping law & order and enforcing the rules laid down by Governor Arthur Philip.
A year later, in 1789, Governor Philip created the first Night Watch. He selected twelve well-behaved convicts and organised them into four gangs which patrolled sections of Sydney town.
Probably explains why some people reckon there's so much corruption in the police force!!
