A strict biosecurity lockdown is set to take effect today in the Inner West suburb of Enfield as authorities intensify efforts to contain an outbreak of red imported fire ants. The new control order establishes a 2-kilometre-wide biosecurity zone surrounding the Enfield Intermodal Logistics Centre, where a colony of the invasive and highly aggressive ants was first identified in September.

The lockdown imposes restrictions on the movement of high-risk materials into and out of the designated zone, requiring such materials to undergo treatment, inspection, and official declarations aimed at minimizing the risk of further spread. Red imported fire ants are widely recognized as one of the most destructive invasive species globally, capable of causing significant ecological and economic damage.

The control order is initially scheduled to remain in place for six months before officials review its effectiveness and determine subsequent actions. While the government has stated that the lockdown will not impede residents from going about their daily routines, it acknowledges that certain local businesses may face considerable challenges. Particularly, companies identified as having the highest potential to spread the ants will be subject to more stringent rules, including modified protocols for handling materials and enhanced surveillance measures.

Officials have indicated they will collaborate closely with affected businesses to facilitate compliance with the new biosecurity requirements, aiming to balance containment efforts with operational continuity. The government’s approach underscores the urgency of preventing the invasive ants from establishing broader populations, which could prove difficult and costly to eradicate.
