The Chinese traded with people who had things to trade,they came here in greater numbers when gold was discovered in the 1880s if they had found gold in the North of Australia they would have been into it.
China has never been a colonizer in the traditional sense of the term. However, China has historically been an imperial power and has exerted control over territories and peoples within its sphere of influence. For example, during the Han dynasty (206 BCE - 220 CE), the Chinese Empire controlled large parts of Central Asia and the Tarim Basin, and during the Tang dynasty (618-907 CE), China controlled parts of present-day Tibet, Kazakhstan, Kyrgyzstan, Pakistan, and parts of Central Asia. Additionally, China has had a long history of tributary relationships with neighboring states, in which they paid tribute to the Chinese emperor in exchange for protection and recognition.
