An ongoing probe by Australian regulators that involves several carrier lines over a period of years has resulted in a hefty fine for K Line over price fixing allegations involving the shipment of vehicles.

With a three-month cooling-off period come and gone without a new deal, dockworkers at DP World’s Australian container terminals are putting the heat on the company this week with a series of strikes.

Three terminal operators amend their contracts with land transport businesses after Australia's competition watchdog raised concerns that terms in each of the agreements may be unfair.

A planned strike at Brisbane follows strikes last week at all four of DP World’s Australian terminals in the ports of Fremantle, Melbourne, Sydney, and Brisbane, and the terminal operator says it won't negotiate a new employment agreement while under threat from further industrial action.
