Red imported fire ants found at Sydney logistics hub

Biosecurity response under way following detection at Enfield Intermodal Logistics Centre

A nest of red imported fire ants, described by the Invasive Species Council as one of the world's worst super-pests, has been discovered at the Enfield Intermodal Logistics Centre in Sydney's inner west, prompting a containment response from NSW authorities. The nest, found in a lure used by Commonwealth Department of Agriculture, Fisheries and Forestry officials, has been destroyed and no further nests have been found.

Officials believe the ants were imported to Australia in a shipping container from overseas, rather than arriving from south-east Queensland, where Australia's main fire ant infestation is located.

The nest was destroyed, and specialist fire-ant-detection dog teams have surveyed the logistics hub without finding any other nests. The response will now focus on inspecting and treating properties within a 500-metre radius of the centre and searching for nests within a two-kilometre radius.

The NSW government said local businesses that deal in soil, turf, building materials or vegetation would be contacted to work through measures to identify and treat any fire ant incursion while minimising disruption.

"It's important to note that no further ants have been found, but we are focused on making sure any potential spread is identified and eradicated quickly," Agriculture Minister Tara Moriarty said. "While fire ants are one of the world's most invasive species, they can and have been successfully eradicated in NSW."

Fire ants were previously found at Port Botany in 2014 and were eradicated.

The Invasive Species Council describes fire ants as one of the world's worst super-pests, warning that if the ants became established and spread around Australia they would cost the economy up to $2 billion a year. Advocacy director Reece Pianta said the detection was a reminder of why investment in border biosecurity was so important, and used the news to call for more funding for the national eradication program.

"In south-east Queensland they invade backyards, parks and sporting fields, attack pets and wildlife and threaten agriculture and infrastructure. Sydney does not want to find out what living with fire ants looks like," Pianta said.

Analysis

Why This Matters

  • A fire ant establishment in Sydney would affect backyards, parks, sporting fields, pets, wildlife, agriculture and infrastructure, as it has in south-east Queensland.
  • The detection at a freight hub points to shipping containers as a pathway for the pest, a concern that extends beyond Australia to any country receiving container freight.
  • If fire ants became established and spread, the cost to the Australian economy could reach $2 billion a year, according to the Invasive Species Council.

Background

Red imported fire ants, native to South America, are regarded as one of the world's most invasive species and a major threat to agriculture and public health. Australia's main infestation is in south-east Queensland, and this latest detection was judged to have arrived independently from overseas rather than from that site. NSW has dealt with fire ants before: a detection at Port Botany in 2014 was successfully eradicated, and authorities will look to repeat that outcome.

Key Perspectives

NSW government and Agriculture Minister Tara Moriarty: Authorities say no further ants have been found and the priority is identifying and eradicating any potential spread quickly, while keeping disruption to local businesses to a minimum. The successful eradication at Port Botany is cited as evidence the pest can be contained.

Invasive Species Council: The discovery is a reminder of why border biosecurity investment matters, and advocacy director Reece Pianta used the news to call for more funding for the national eradication program, warning of the consequences if fire ants become established in Sydney.

Critics/Skeptics: The council's funding call implies the national eradication effort is not fully resourced, and the appearance of fire ants at a second Sydney site in a decade shows the pest can repeatedly reach Australia through trade routes. The two-kilometre search will test whether this was an isolated nest or a larger incursion.

What to Watch

  • The outcome of inspections and treatment of properties within 500 metres of the logistics centre, and nest searches within a two-kilometre radius.
  • Whether further nests emerge in coming weeks, which would signal the incursion is larger than a single detection.
  • Funding decisions for the national fire ant eradication program.
  • How businesses handling soil, turf, building materials and vegetation respond to the government's contact and compliance measures.
