Australia stands ready to take back two key ports from Chinese investors if any security concerns are raised, Scott Morrison said.
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.
And Darwin Port is run by Chinese company Landbridge Group, which secured a 99-year lease from the Northern Territory government in 2015 for just $506 million.
In November 2015, the Northern Territory government decided to lease the Port of Darwin (pictured) to a Chinese company for 99 years
Pressure is mounting on the federal government to take back key infrastructure from Chinese control as relations with Beijing hit a new low.
