Ports operator DP World Australia says it is working closely with national cyber security experts and the Federal Government following an incident that has disrupted freight movement at its terminals. 

The company said this morning that operations had resumed at the ports following successful tests of key systems overnight and it expects about 5000 containers will move out of the four terminals today. 

Home Affairs and Cyber Security Minister Clare O’Neil said yesterday that the incident was “serious and ongoing”. 

“DP World manages almost 40% of the goods flowing in and out of our country, and this incident is affecting the ports of Melbourne, Fremantle, Botany and Brisbane,” she said on X. 

DP World says it’s continuing to work closely with, and appreciates the support of, the National Cyber Security Coordinator, the Australian Cyber Security Centre, the Australian Federal Police, Ms O’Neil, Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King and other government regulators and bodies. 

“Importantly, the resumption of port operations does not mean that this incident has concluded. DP World Australia’s investigation and ongoing remediation work are likely to continue for some time,” it said.
