Fire ants have recently been discovered in Tweed Heads, New South Wales, which has sparked urgent calls for measures to prevent their spread further into the state. The New South Wales government announced the successful destruction of an immature nest and has conducted a 500-metre survey around the site to detect additional fire ant activity.
In response to this biosecurity threat, officials are undertaking genetic analysis to trace the origin of the infestation, while also tracking the movement of potentially contaminated materials. A new control order will establish a 5 km zone to manage the movement of high-risk items and implement necessary treatment actions.
Reece Pianta, the advocacy manager for the Invasive Species Council, highlighted the situation as a national biosecurity emergency, calling for the Albanese government to match Queensland’s recent $24 million funding for suppression efforts and to support a comprehensive eradication program. Pianta warns that any extension of the fire ant containment area would pose a dire threat to Australian agriculture, native wildlife, and public health.
Fire ants are regarded as one of the world’s most dangerous invasive species, known for their painful stings that can lead to severe allergic reactions in humans and represent a substantial risk to pets, livestock, and local ecosystems. The NSW Farmers Association has echoed these concerns, with committee chair Tony Hegarty labelling the repeated sightings of fire ants as indicative of a significant biosecurity failure. He emphasises the urgency of enhanced measures, warning that while Australia currently has $100 million allocated for biosecurity, the potential costs of fire ants could reach $60 billion over the next three decades.
Anyone in New South Wales who suspects the presence of fire ants is encouraged to contact the Biosecurity Helpline or report their findings online. The situation requires immediate attention and action to safeguard the region from the potentially devastating impacts of these invasive pests.
