Both China and Australia are countries with large maritime resources and marine fishery resources. How to more efficiently utilize these rich maritime resources and further develop the marine fishery economy are common issues faced by both countries. The current status and characteristics of Australian marine fishery engineering, adopts methods including research, big data statistics, and specific case analysis to distinguish the advantages and disadvantages of Australian marine fishery engineering were analyzed in this article. The basis, advantages, difficulties and challenges of Sino-Australian marine fishery economic cooperation, and investigate the prospects for deep cooperation between China and Australia in the field of marine fisheries to achieve mutual beneficial cooperation were analyzed. It is concluded that the launch of Sino-Australian marine fisheries economic cooperation and opening of the Blue Economic Corridor is an important part of China's 'Belt and Road' initiative. It serves the fundamental interests of the two countries, as well as complements both respective economies.
