Why did Australia become a place where British criminals fled?

At that time, Australia was actually a British colony. At that time, the British wanted to control Australia better, but they didn't want the local people to make too much sacrifice, so they let British criminals come to Australia. These British criminals are mainly responsible for developing the Australian mainland, which will also make British colonial rule more stable. The polarization in Britain after the industrial revolution was very serious. At that time, those capitalists began to squeeze the British labor force, making the life of the bottom people even poorer. In this environment, the crime rate of the British people has greatly increased. According to statistics, the crime rate in Britain has increased by about seven times in just a few years. At that time, the whole British people began to pay attention to human rights under the influence of the European Enlightenment. At that time, the British rulers could not deal with these criminals through the death penalty as before. How to arrange these British criminals reasonably became a fact that the British rulers had to pay attention to at that time. You know, at that time, British prisons were limited, and they simply could not bear so many British criminals. 1770, Captain Cook of England came to Australia and started killing Australian aborigines. It should be that he later occupied Australia. In order to better consolidate British colonial rule, the British should actually send more British people to Australia. But because Britain is far away from Australia, it is a great loss for Britain to go to Australia every time. Although the British rulers wanted to send native British people to Australia at that time, in fact, these British people did not have much desire to be stationed in Australia. So at that time, the British government added fuel to the flames and exiled all the redundant criminals to Australia. In this way, these British criminals can not only help the British government to rule Australia, but also let these criminals help the British government to explore the Australian mainland. At that time, it was in this way that Britain properly solved the problem of dealing with criminals and brought great benefits to Britain.
