As a top destination for Chinese investment overseas，Australia has been an important country to engage for the purpose of Belt and Road Initiative. China's capital inflow into this sector topped A ＄ 4.34 billion in 2016，accounting for 28% of Chinese investment in Australia that year. However，as predicted in last year's report，“uncertainties emerged for Australia to remain an attractive FDI destination”given ongoing shifts in domestic politics. In fact，for year 2017-2018 Australia garnered enough support at home to push forward major legislative and administrative responses to tighten up control on foreign investment in infrastructure，especially those identified as critical infrastructure. As a result，Chinese investment in this area saw an 89% plunge in 2017 and hasn't recovered yet this year. This report analyses Australia's legislative，administrative and institutional changes since 2016，but mostly concentrating in 2017-2018，to better monitor and guard against national security risks in infrastructure FDI and explores Australia's efficiency in this wave of policy response，as the first country to effect such changes，ahead of countries including the US，Germany and Britain. Against the background of Victoria's newly signed BRI MOU with China，the report also examines prospect of future partnerships under the BRI framework，most notably areas，forms and structures that will be acceptable to both.
