Ports operator DP World said Sunday it had made "significant strides" towards resuming normal freight trade at major gateways into Australia, which have been crippled for two days by a cyber incident.

Government agencies held crisis talks over the weekend in response to what Home Affairs and Cyber Security Minister Clare O'Neil described as a "serious and ongoing" breach that has disrupted operations at key ports.

"DP World manages almost 40% of the goods flowing in and out of our country," she added in a post on X.
