THE New South Wales Government has confirmed that an immature fire ant nest was detected and treated on a property site in Tweed Heads yesterday, Wednesday, July 3.

A report of suspected fire ants late Tuesday resulted in swift action by the NSW biosecurity team, who discovered and treated the non-reproductive nest.

The National Program and the NSW Department of Primary Industries and Regional Development also surveyed the immediate 500 metres surrounding the site.

Genetic analysis has commenced on the specimen fire ants to determine the likely source, and a new Biosecurity Emergency Control order has been issued, establishing a 5 km zone.

Minister for Agriculture Tara Moriarty said the NSW fire ants’ systems and response plan were in action, and the government’s preparation and education had fostered a vigilant local and business community.

“An investigation was immediately commenced following the report of suspected fire ants, and the discovery of an immature nest led to its destruction,” Moriarty said.

“The NSW Government is committed to proactive early detection surveillance, focusing on high-risk areas and employing advanced tracking and modelling techniques.

“Biosecurity is a shared responsibility, and we need everyone working together to manage the threat of fire ants.”

NSW Chief Invasive Species Officer Scott Charlton said the investigations and surveillance were underway, and the fact that the nest was immature was reassuring.

“A vigilant pest control contractor at the site quickly identified suspected fire ants,” Charlton said.

“This is yet another reminder that vigilance, awareness and early detection are critical to keep these things out of NSW.

“The NSW team has completed more than 1,900 surveillance events across the state, to prevent the spread of fire ants from infested areas of Queensland, including proactive early detection surveillance across high-risk sites.”

Tweed residents can call the helpline on 1800 680 244 or submit an online form to report any suspected fire ants.

Breaching the emergency biosecurity order carries penalties of up to $1.1 million for individuals and up to $2.2 million for corporations.
