I’ve been pressing the federal government on its oversight of the fire ant eradication program. While Canberra funds half of this national program, responsibility for delivery lies with the Queensland government. Landowners are reporting serious issues — intimidation, property damage, and environmental harm — yet the department insists there’s “no evidence” of wrongdoing.
I asked questions about residents’ rights to refuse access when health or safety is at risk. What happens if someone has asthma and chemical exposure could trigger an attack? What about pets, livestock, or crops at risk? The department wouldn’t give me an answer. Even more alarming, I’ve received reports of chemicals being used unlawfully — S-methoprene dumped into waterways, aerial spraying of pyriproxyfen in areas with no fire ants — all in breach of permit conditions.
And then there’s Dawson Creek in Samford Valley where locals report native species have been killed. Where’s the environmental safety research proving these chemicals are safe for people and wildlife? The department claims the program is “supported by science,” and insists it won’t suspend funding—even when breaches occur. That’s taxpayer money being spent on a program that could be putting lives, health, and ecosystems at risk.
I’m not backing down. Biosecurity matters, yet it should never come at the expense of people’s rights, health, or trust.
If you’ve had problems with the fire ant program, please reach out — I’d like to hear from you.
— Senate Estimates | December 2025
Transcript
Senator ROBERTS: Thank you for appearing again today. What oversight is the federal government exercising to ensure the states are successful in eradicating fire ants and are doing so safely?
CHAIR: I will say that we have touched on fire ants, but please feel free.
Senator ROBERTS: Yes. I raised this at the last Senate estimates. I’ve got quite a few questions.
CHAIR: Carry on.
Ms Sawczuk: As we mentioned a moment ago, we continue chairing the national governance—the national management group—around the program. There is a program-level meeting and also a consultative meeting. That is happening regularly, and the next national governance meeting is on 15 December. Taking on board the concerns that you raised at the last estimates hearing and correspondence that has been provided to the department but also to the program in Queensland, we have been engaging with the program to pass on the specific feedback that has been provided. They have confirmed that they are taking on board any considerations raised by landowners, but there has been no damage to property and also no unlawful behaviour in regard to accessing properties for treatment et cetera. The safety of the program is absolutely critical. It’s something that is discussed at the national management meetings in particular, and we take quite seriously any concerns that have been raised around specific treatment types, whether it’s broadscale treatment or direct nest injection. The APVMA is the authoriser of those particular treatments and can confirm that the program has been undertaking independent toxicology analysis, which has found that there is no direct correlation with any negative impacts to animals et cetera around the fire ant treatment.
Senator ROBERTS: Well, I’m stunned. When you say ‘take on board’, what do you mean? What action do you take specifically to hold them accountable?
Ms Sawczuk: We directly engage at all levels.
Senator ROBERTS: What do you mean by that?
Ms Sawczuk: We meet with the program to talk about the specifics.
Senator ROBERTS: Where do you meet?
Ms Sawczuk: Virtually and face to face, and quite regularly. Every piece of correspondence that has been sent through is provided directly to the program, and then we have followed in meetings to understand the specific circumstances. While there are some claims, there is definitely no evidence that would warrant concerns about anything untoward about the behaviour of the program. I appreciate that there are some sensitivities for specific landowners et cetera, but all of the treatment, and all of the action by the program, has been within the Queensland biosecurity legislation.
Senator ROBERTS: There have been assaults on people, injuries to innocent people. There has been complete disregard for people’s health. There have been violations of the permits, which I’ll get onto. So I don’t
accept your response at all. Last time we appeared at Senate estimates on this topic, we were deluged with people saying they would contact you. Have you been contacted by residents?
Ms Saunders: We have received correspondence since our last hearing, and, as Ms Sawszuk just outlined, all that information is provided to the program, who’s ultimately accountable for delivery, compliance, assurance and oversight of the work that occurs.
Senator ROBERTS: Who is responsible?
Ms Saunders: The relevant state department in Queensland is responsible. There are ongoing discussions with them in regard to the issues that have been raised, but, ultimately, it’s the Queensland government that is
accountable for delivering the program.
Senator ROBERTS: So the state is responsible but you’re funding it to do these activities.
Ms Saunders: The nation, because it’s a national program, to which we contribute funding—correct.
Senator ROBERTS: The majority of funding.
Ms Saunders: It’s 50 per cent.
Senator ROBERTS: For eradication. You don’t seem to be aware of the overreach and intimidating tactics being undertaken by the state government, particularly in South-East Queensland, forcing their way onto
properties unlawfully, causing fear and distress to landowners, upsetting women and terrifying crying children, polluting the environment, negligently and wilfully killing fauna and pets. Are you aware of those?
Ms Saunders: I know you’re disappointed with the response that we give you, as a department, but I can only give you the same advice I gave you at the last hearing on these matters, and that is that we are not accountable or responsible for the issues you’ve raised, nor do we have evidence of them.
Senator ROBERTS: Since when is it okay for gates and fences, with your funding, to be broken down, with police threatening those with reasonable excuses who withhold consent—for strangers to force their way onto
properties and sneakily and deceptively distract people from their properties, with a view to spreading poison, when there are no fire ants on their property, not even in the valley?
Ms Saunders: I’m not sure what else I can add to our earlier evidence on this.
Senator ROBERTS: This is exactly what happened recently at Beechmont and Laidley, when property was damaged and officers behaved like criminals in a home invasion while trespassing on private land. The violence came from the officers, not the landowners. The landowners have been professional and peaceful. Why?
Ms Saunders: These are the responsibilities of the state government. I’d really encourage those allegations and concerns being directed to them. As indicated by the deputy, the legislation which they’re operating in
compliance with is entirely the responsibility of the state government.
Senator ROBERTS: But you’re funding it. I attended another property some kilometres away from the two locations I mentioned that had multiple fire ant nests—I saw them six metres apart in places and two or three
metres apart in places—that the program refused to attend and treat. Why is that?
Ms Saunders: I can’t comment.
Senator ROBERTS: Would you like the name of the property?
Ms Saunders: Certainly, we’re happy to take any information you have. We would relay it to state government for action, noting we have no authority.
Senator ROBERTS: A property owner may obstruct and refuse access to officers if they have a reasonable excuse. Is it a reasonable excuse to obstruct when a resident has an illness, such as asthma or other respiratory
ailment, confirmed by a medical certificate as likely to be made worse by exposure to toxic chemicals, particularly when being sprayed? Is that a reasonable excuse?
Ms Saunders: I’m not prepared to comment.
Senator ROBERTS: Is it a reasonable excuse to obstruct when the chemicals represent a threat to domestic animals—dogs, cats and birds—if they’re exposed to the toxic chemicals, including chickens?
Ms Saunders: I’m not prepared to comment.
Senator ROBERTS: Is it a reasonable excuse to obstruct when the chemicals that you’re funding represent a threat to poultry, livestock and fruit and vegetables growing on the property?
Ms Saunders: If you have a long list of allegations, we’re happy to take those allegations and raise the matters with the Queensland government.
Senator ROBERTS: Okay. I will do that with most of these questions. Is it a reasonable excuse to obstruct when the chemicals are not being administered according to the safety requirements under the permits issued by
the APVMA?
Ms Saunders: I don’t have a comment.
Senator ROBERTS: Just yesterday I was told—this is so common—that the program distributed S methoprene directly into a Samford waterway, against the safety rules for application, by way of a drone. Are you aware of that?
Ms Saunders: No.
Senator ROBERTS: Aerial application of pyriproxyfen is occurring on a wide scale on areas where no fire ants have ever been identified, when the permit number PER87728 clearly states by way of restraint:
DO NOT apply as a preventative measure for Red Imported Fire Ant control. If the permit has changed, why? Are you aware of that?
Ms Saunders: No.
Senator ROBERTS: Is it a reasonable excuse to obstruct when the administering authority has already admitted to disastrously polluting a significant waterway in the Samford Valley near Brisbane, Dawson Creek,
killing extensive native water, reptile and insect species? I’ve seen that. Is that a reasonable excuse?
Ms Saunders: I couldn’t comment on that.
Senator ROBERTS: Okay.
Senator WHISH-WILSON: Did you take photos?
Senator ROBERTS: Yes.
Senator WHISH-WILSON: Can you produce them for us?
Senator ROBERTS: The locals can.
Senator WHISH-WILSON: What about you? You said you took photos.
Senator ROBERTS: No, the party I was with took photos.
Senator WHISH-WILSON: Oh, I see.
Senator ROBERTS: Where is the environmental safety research that’s been done to establish the safety of humans and our native birds and small animals when poisoned insects form part of their food chain? Have you
done that?
Ms Saunders: I’ll hand over to Dr Bertie Hennecke—he can probably comment further—but the program is absolutely supported by scientific evidence and safety. It’s been looked at nationally, with people who have
credible experience in this field, all of whom are satisfied with the arrangements that are in place and the chemicals that are being used for the purpose intended.
Senator ROBERTS: In distributing these chemicals, they’re breaching the permits—they’re breaching the authorisation—to use the chemicals. Does that bother you? You’re funding it.
Ms Saunders: If there’s evidence of that, we’re happy to take that evidence and take up the matter with the Queensland government.
Senator ROBERTS: Will DAFF step up to pay compensation to those affected by the misapplication of the Fire Ant Eradication Program?
Ms Saunders: It wouldn’t be the responsibility of the department—
Senator ROBERTS: You’re funding it.
Ms Saunders: to do that.
Senator ROBERTS: Why are you funding this using taxpayer money, doing injury to the environment and to people?
Ms Saunders: It’s a national program aimed at eradicating red imported fire ants. It’s that simple. We know it’s incredibly invasive and, if it were to take hold, would have catastrophic implications for the country. That’s
why we’re doing it.
Senator ROBERTS: So why are you putting lives and the health of humans and the environment at risk?
Ms Saunders: We don’t have evidence of that.
Senator ROBERTS: Would you like some?
Ms Saunders: As I’ve said several times now, I’m happy to take information you have, and we’ll take it up with the Queensland government.
Senator ROBERTS: Will you stop funding this program, or at least suspend funding of this program?
Ms Saunders: No, we won’t.
Senator ROBERTS: Okay.
