Australia's second-largest sugar producer, **Mackay Sugar**, has confirmed it is responding to a significant cybersecurity incident. The attack has directly impacted parts of its operations, leading to the immediate shutdown of its **Farleigh** and **Racecourse** mills in Queensland's **Mackay** region. This disruption has cascading effects, with growers instructed by **Canegrowers Mackay** to cease all sugarcane harvesting until further notice. Both affected mills had only recently commenced their annual sugarcane crushing season, making the timing particularly impactful. While **Mackay Sugar** has not disclosed the nature of the cyberattack, whether data was compromised, or if ransomware was involved, the company is actively working with cybersecurity experts and local authorities to investigate and restore its systems safely. Temporary measures have been implemented to maintain essential operations and minimize ongoing disruption. The company, which generates over $420 million in annual revenue and supplies raw sugar to domestic and international markets including South Korea, Indonesia, Japan, and Malaysia, is communicating with its employees, growers, and business partners, promising further updates as the situation evolves. Growers in the **Marian** district remain unaffected, as the company's third mill in that area is not scheduled to begin operations until next week.
