Labor MP Luke Gosling says the 99-year leasing of the Port of Darwin to Chinese investors in 2015, was a result of "a combination of errors", but ultimate responsibility rests with the then-Treasurer, Prime Minister Scott Morrison.
"It was a decision taken by the Country-Liberal Party NT government at the time in 2015. I was very critical of the decision at the time," he said.
"People don't quite understand the role of the Foreign Investment Review Board [FIRB], which is to provide advice to the government.
"Ultimate responsibility rests with the Treasurer, and in 2015 when the port was leased for a year under a century, the treasurer was the current Prime Minister, Scott Morrison, so I think there was a combination of errors."
