I've been in contact with the company again this morning and they're making good progress," the government's Cyber Security Coordinator Darren Goldie told ABC Radio.
After spotting the breach, DP World, one of a handful of stevedore industry players in Australia, disconnected internet, significantly impacting freight movements, Goldie said.
The company, part of Dubai's state-owned DP World, did not immediately respond to a request seeking comment.
In a statement on Sunday, DP World said the company was testing key systems crucial for the resumption of regular freight movement.
The breach comes as the government prepares to release soon details on its proposed cyber security laws.
