Global insecurity about Chinese investment seems to be the main reason for the decline. However, recent policy changes in China are not helping, according to the report.
For example, while Chinese businesses still see Australia as an attractive country in which to invest, they are finding it harder to move money out of China.
"Large strategic investments in resources, energy and infrastructure have given way to smaller investments and in projects that are tactical and directly linked to Chinese consumer market demand."
