A NSW company tipped off authorities to the illegal movement of its cattle, triggering the investigation that led to the largest-ever biosecurity fine under a Queensland law. Argyle Foods Pastoral Pty Ltd, based in New South Wales and the ACT, was fined $45,000 in November 2025 for moving livestock into Queensland without the required records. The company is operated by directors Bryce and Lachlan Graham, who are brothers.
