Mackay Sugar Cyber Security Incident Update 3

Mackay Sugar continues to respond to a cyber security incident affecting some of our operations.

We have completed a successful limited manual crushing operation at Farleigh Mill, processing cane harvested prior to the incident. This was a step forward in our recovery efforts, giving us confidence that critical operational functions can continue to be restored safely.

Significant progress has been made over the weekend in restoring the systems that support cane supply, harvesting and mill operations.

Steam trials are now underway, and subject to final validation activities, some harvesting is expected to recommence this week in preparation for the staged restart of crushing operations later this week. We have taken the responsible course of action in advising growers and harvesters not to recommence harvesting until we advise them to do so.

Our ongoing priority remains the safety of our people and protecting operational systems. Specialist cyber security experts continue to work alongside our teams and relevant authorities to investigate the incident and restore systems safely.

We have also reported the incident to the appropriate authorities, and we will continue to adhere to our regulatory obligations.

We are communicating directly and regularly with our employees, growers and key partners. We recognise the impact this incident is having on our growers, and we are doing everything we can to support them and to safely resume full operations as soon as possible.

We take our responsibility to protect our systems, operations and information very seriously. We apologise for any disruption this incident has caused and will continue to provide updates as we continue our investigation.
