Australia’s Fire Ant Battle Faces Misinformation Crisis Amid Eradication Efforts

Australia’s national fire ant eradication program is struggling against a tide of online misinformation that has eroded public trust and created space for “anti-government narratives,” according to a newly released independent review.

The invasive species has now infested approximately 850,000 hectares across south-east Queensland and northern New South Wales over the past three years, with additional breakout infestations detected in Central Queensland, threatening to expand their territory further.

“The program’s cautious approach to messaging has limited its ability to respond quickly and proactively, leaving space for emotionally driven opposition and anti-government narratives,” the review stated, highlighting how misinformation about chemical use and environmental impacts has shaped negative perceptions about eradication efforts.

Despite these challenges, the review concluded that eradication remains feasible if “significant issues” are resolved “promptly.” All 19 recommendations from the review have been accepted by the National Fire Ant Eradication Program.

Marni Manning, general manager of operations for the program, acknowledged the communication missteps that allowed misinformation to flourish. “We looked at it and went ‘that’s fanciful — no one is going to believe that,'” Manning said. “What we didn’t realize is that without counter information, it creates a vacuum.”

The review specifically called for major changes in how the program communicates with the public, noting that “community trust is being eroded by unclear messaging, limited visibility of success stories and fatigue.” It also found that field staff “often lack the tools and authority to respond to community concerns or explain program decisions, creating gaps in engagement and trust.”

Fire ants pose a severe threat to Australia’s ecosystem and economy. They can swarm and kill native species including reptiles and small mammals, while causing serious injuries to livestock and pets. Economic modeling by the Australia Institute estimates that if left to spread unchecked across the country, fire ants would cost the federal government $22 billion by the 2040s.

In response to the communication challenges, Manning said the program has begun asking qualified experts, farmers, and industry groups to share their experiences with fire ant infestations. The review also suggested embedding program officers into local councils to better coordinate eradication efforts.

“They are actually really well-skilled in biosecurity,” Manning said of local councils. “What we are better doing potentially is providing them access to additional equipment, product and training.”

The current four-year eradication plan, set to be revised in 2027, has received $592 million in combined state and federal funding. However, the review found significant community confusion about the strategy itself, particularly regarding the distinction between “eradication zones” and “suppression zones.”

In eradication zones throughout south-east Queensland, teams from the National Fire Ant Eradication Program directly treat and exterminate nests. Within these areas are designated suppression zones, where landholders are responsible for treating nests found on their own properties. As ant populations are eliminated, the eradication zone gradually contracts inward toward the coast.

Reece Pianta, advocacy manager from the Invasive Species Council, emphasized that the purpose of this strategy needs better explanation. “[Suppression] won’t result in a permanent removal of fire ants from an area,” he explained. “It’s just meant to maintain low fire ant density levels while the eradication program does its work.”

Last year, the Queensland government announced a $24 million Fire Ant Suppression Taskforce to assist landholders within the suppression zone. However, the review noted poor coordination between national and state programs has caused confusion that further fuels misinformation and undermines public confidence.

“The bureaucratic language that we adopt so readily actually serves as a barrier when we have a conversation with broader community,” Manning acknowledged. “Essentially, there’s no split — suppression is part of eradication.”

Despite the challenges, Manning remains optimistic that eradication by 2032 is still achievable. “We have eradicated eight genetically distinct incursions of fire ants in Australia and we have contained them — no other country has done that,” she said.
