DP World Australia's website and IT systems that were the target of a cyber attack have come back online a few hours ago, according to a report by the BBC.
DP World Australia said its ports resumed operations at 9 am local time following successful testing of the systems.
The company added that it expects to move approximately 5,000 containers out of its four Australian terminals today.
The perpetrators of the attack have not yet been identified. DP World had disconnected its systems from the internet when the attack occured last Friday.
"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," the company added.
The attack has not caused any major disruption in Australian supply chains which are gearing up for the Christmas shopping season.
