There’s a lot of confusion about the Turnbull government’s bizarre move to ban both a Chinese government company (State Grid) and a publicly listed Hong Kong company (CKI) from bidding for NSW government-owned assets.

Since last week’s bombshell, much has been said about previous offshore purchases of Australia’s critical power infrastructure, so below is the definitive list of foreign power investments since the Kennett government kicked it off in Victoria 23 years ago.

US and British firms were the dominant early investors before Chinese and Singaporean players entered the fray in late 1999.

There have been 17 different investments by Asian players over the past 17 years, with the majority being controlled by private investors, notably through Li Ka-Shing’s now banned CKI along with China Light and Power, a public company that has Sir Rod Eddington on its board.

When you add up the investments by Singapore Power and Chinese government companies, Australia does have more foreign government investment in its power sector than any other Western democracy. However, there has never been a known security problem with any of this and with so much already committed, can you really turn off the tap now?

Anyway, here is the definitive list, with Asian investments in italics.
