Pressure is mounting on the federal government to take back key national assets from Chinese control amid fears the communist superpower could disrupt our crucial infrastructure using advanced cyber attacks.
Two of Australia's most important harbours - Darwin Port and the Port of Newcastle - were leased to Chinese companies as state governments cashed in on lucrative private investment.
The Port of Newcastle, the world's biggest coal port, was handed over to a Chinese-backed consortium for 98 years for $1.75 billion when Mike Baird was NSW Premier in 2014.
The decision means the port is half controlled by Aussie company Gardior and half by China Merchants Port Holdings Company until 2112.
