Detection of fire ants in Queensland 800km from closest infestation sparks fury over gaps in eradication funding
The discovery has prompted fury among the Invasive Species Council, who have questioned how the invasive pest had travelled almost 800km from the closest known infestation zone.
The National Fire Ant Eradication Program on Friday urged businesses and industry to stay alert for fire ants after nests were discovered at Moranbah, a coalmining town about 150km inland from Mackay.
They said program eradication officers first visited the BHP mine on 9 July, and the nests were destroyed using direct injection.
'The program … will conduct eradication activities across the impacted area – including intensive surveillance and broadscale treatment – to ensure any present fire ants are eradicated,' they said in a statement.
'Genetic analysis and tracing activities are being conducted to help determine how the ants reached Moranbah.
'Detections outside the south east Queensland eradication zone are serious and highlight the risk posed by movement of materials that can carry fire ants.'

A spokesperson for BHP said keeping the community safe was the company's 'top priority' and it was 'working closely' with the National Fire Ant Eradication Program to support the 'rapid containment, treatment, and eradication of this fire ant detection'.
Red imported fire ants are one of the world's worst invasive species, considered a pest due to their painful stings and potential to cause severe ecological, agricultural and economic damage.
Twenty-three people in Queensland were hospitalised with serious fire ant stings amid a surge in reports in the aftermath of Ex-Tropical Cyclone Alfred.
They were first detected in Australia in Queensland in 2001 and have since been found in parts of New South Wales and Western Australia. They are a category 1 restricted matter under the National Environmental Biosecurity Response Agreement.
The Invasive Species Council said the breach outside existing biosecurity zones, which are spread throughout Queensland, was unacceptable and pointed to the need for additional funding.
Its advocacy director, Reece Pianta, said she was 'incredibly angry'.
'In the last week, we've had another detection in New South Wales, an interception in Western Australia and now the first outbreak in Central Queensland,' she said.

'This is not bad luck, it's a spectacular failure because of known gaps in funding, enforcement and surveillance.
'Australia's last chance to eradicate deadly fire ants is being destroyed because Australia's governments are dithering and delaying critical funding increases.'
Pianta pointed to a recent Senate inquiry into red imported fire ants which found the government program tasked with their elimination was an 'absolute shambles' and that an independent eradication body was urgently needed.
'We have warned for two years that there is a major gap in funding for suppression, with nest densities off the charts south of Brisbane,' Pianta said.
'Now we're seeing the consequences play out – fire ants are slipping through the cracks and turning up in places they've never been before.'
A spokesperson for the federal government said the Queensland government-led National Fire Ant Eradication Program aimed to eradicate red imported fire ants from south east Queensland by 2032 and continued to respond quickly to new detections outside the containment zone.
'Our government is contributing a record investment of just under $300m for the program, representing around 50% of the total national cost-shared budget,' they said.
'This is nearly four times more investment than was the case at the end of 2021-22.'

FLOURISHING AFTER 50: My daughter's expensive wedding is ruining our retirement plans - can we cut back without losing face?
Dear Vanessa, I'm feeling sick with worry and don't know who else to turn to. My husband and I are both in our late 50s. We've worked hard all our lives and were hoping to retire by 70 - not extravagantly, just comfortably. Our eldest daughter is getting married next year. We adore her and want her to have a lovely day, but a few months ago my husband told her fiancé's family that we would pay for the entire wedding. He did it to look generous - especially because the groom's parents are very well-off and traditional. Now he says he can't back down without losing face. The problem is the wedding has ballooned to nearly $60,000 thanks to a huge venue, band, flowers, the lot. My husband insists we'll 'make it work' but I know we can't afford it without dipping into our mortgage offset or even our retirement savings. We still have some debt and we're not rich by any stretch. I've tried talking to my husband but he just gets defensive and says he won't 'look cheap' or let the other side think we can't provide. Our daughter is so excited and I feel terrible bringing it up with her - but I'm so angry that we're risking our future to keep up appearances. Should I push him harder? Should we tell our daughter she needs to scale back? Or should I just bite my tongue and find a way to pay - even if it means we work longer? I feel so stuck. Worried Mum, NSW. First of all, I really feel for you. This is exactly the kind of family conflict about money that can quietly undermine the retirement you've spent decades building. A wedding is meant to be a joyful celebration - not a $60,000 drain that chips away at your future security. But this is about more than one big day - it's pride, old-fashioned expectations and the fear of embarrassment when money truths come out. My first piece of advice is to move this out of emotion and into facts. Sit down with your husband and map out exactly what paying for this wedding means for your plan to retire by 70. For example, if you have $500,000 in retirement savings at around 58 and plan to retire by 70, spending $60,000 now could mean losing more than $110,000 by the time you reach retirement just from the lost growth alone. Most people forget the real cost isn't just what you spend today - it's what that money could have grown into for your future. To see this clearly, run a quick scenario using the free Moneysmart Retirement Planner - you'll find it here. Plug in your real numbers - your current balance, contributions and target retirement age - then run it again with $60,000 less. That difference is your real cost of 'keeping up appearances'. Once you both see the impact in black and white, you can plan a gentle but honest chat with your daughter. Tell her you love her and want her day to be beautiful, but you can't risk your own security to impress anyone. It's one of the best lessons you can pass on: big milestones should never come at the cost of your long-term wellbeing. If your husband still can't face it, I strongly recommend bringing in a neutral third party - a financial adviser or coach - to show him the numbers without blame or conflict. Sometimes that's all it takes to break through pride. If you'd like help finding the right adviser to guide you through this, you can start here. You've both worked too hard to spend your later years worried about money. Be brave enough to have this tough conversation now - your future self will thank you for it.

‘The whole back of my HiLux was covered in rats': what to do about Sydney's growing vermin problem?
Nathaly Haeren has seen patios in Sydney collapse because brown rats have tunnelled under and created sinkholes. She's been electrocuted in the roof of a house after they chewed through air conditioning wiring. She's even visited a hairdresser where they'd gnawed a circle through double brick. More recently, Haeren has started seeing rats standing in the street in the middle of the day, 'oblivious' and unbothered – like they just don't care. 'It's the destruction they cause that blows my mind, that scares me, because I'm competing against them,' the owner of Pesty Girls pest management says. 'Rats need to keep gnawing to keep their teeth down. Their strength is like iron. And they can flatten to the size of your thumb – they've got hinged ribs … I need to be 10 steps ahead.' Haeren says rats have become a problem 'all across Sydney'. And her requests have spiked to record levels since the pandemic. Anecdotally, numbers are high. A string of viral videos showing rat incursions into typically human spaces in recent months has instilled terror into the hearts of some Sydneysiders. In December, rodents made headlines when 'giant rats' were filmed 'brazenly' scurrying around the Westfield food court in Parramatta. A month later, at least half a dozen rats were filmed running wild in the kitchen of a late-night kebab shop on Oxford Street, deterring some from the business. But nobody really knows how many rats live in Sydney. There's no rat census and given that a rat's pregnancy lasts just three weeks and can produce a litter of more than a dozen pups, any population count is at risk of becoming quickly outdated. Haeren attributes their visible spread across the city to construction pushing them above ground and changing bin cycles allowing residential waste to sit for longer periods. New research suggests invasive rats are becoming increasingly resistant to poisons, posing challenges for councils and pest controllers. The study's author, Edith Cowan University PhD candidate Alicia Gorbould, says the finding should be a warning sign. 'Australia has been using these poisons for more than 50 years in an unchecked way, with few restrictions,' she says. 'Many countries are putting restrictions on regular pesticides, but if we continue as we are, we can also feed into that cycle of resistance. 'We need a more coordinated approach to rodent management, and that's not happening.' In 2019, the city of Sydney reported an increase in the vermin population that the council said had been encouraged by 'unprecedented' levels of construction. Sydney's first outbreak of leptospirosis, which is spread through rodent urine and killed seven dogs, was linked to the 2019 explosion in the rat population. The disease can also be fatal in humans. Rats have been associated with dozens of human diseases and parasites around the world, including indirectly spreading Lyme disease, plagues and typhus through fleas. Over the past 10 centuries, rat-borne diseases may have taken more lives than all of the wars ever fought. Since the 2019 outbreak, leptospirosis has popped up in urban areas around Sydney, the Australian Small Animal Veterinarians president, Julia Crawford, says. She and the founder of Southern Cross Vet, Sam Kovac, argue more research and surveillance are needed in order to prevent further outbreaks of the disease and deaths of beloved dogs. The harm rats can pose goes beyond our family pets. A city of Sydney spokesperson says the greatest health and safety risks posed by rats are disease transmission, food contamination via their droppings, urine and hair, and structural damage. The spokesperson says recent sightings and complaints also suggest rodents are a 'key concern' for residents in social housing estates, who shared communal bin rooms. The council spends about $240,000 a year on pest control. Alongside rat baits, it operates a 'risk-based rodent control program' on streets and at parks, manned by more than 100 staff and contractors with the assistance of 40 electronic multi-catch units in locations where rodent activity is high. The baits are rotated on a quarterly basis to prevent rats becoming resistant to their active ingredients. During severe infestations, licensed pest control contractors also carry out targeted burrow baiting. Across the state, councils and private operators are responding to concerns about increased rat populations with a mixture of methods. Shaun Bankowski has operated his pest control business, MOA Contract Shooting, throughout New South Wales since 2015. He says he has never been in higher demand to deal with rat outbreaks – from shopping centres to food manufacturing sites, chicken farms and warehouses. 'We've had sites where we've shot over 650 rats in four hours,' he says. 'The whole back of my HiLux was covered in rats – 15cm deep.' Most services use the integrated pest management method, which first eliminates the reasons why rats are drawn to the site, like clutter and food sources, then lays down traps and baits. But Bankowski says that's no longer sufficient. 'Say you've got 100 rats – 80% of them will die from the poison and the traps, but then you'll have that 20% that are immune,' he says. 'They breed up and then you've got a colony that's immune to poisons. 'I come in, get rid of as much as you can with a shoot and then drop poison on them. That usually knocks them out.' If it sounds grisly, he says, the rats die as humanely as possible. 'I can hit a 50c piece at about 120 metres,' he says. 'We always make sure that we got a clean shot, in the head or in the chest.' Urban rat numbers around the world are increasing due to climate change, urbanisation and growing human populations, forcing cities to grapple with whether to continue to fight the war on rats or concede defeat. In New York, the city's first 'rat tsar' was hired by the mayor in 2023, following a competitive application process that called for 'bloodthirsty' applicants who possessed 'killer instincts'. Not all cities have approached the issue with such murderous intent. In Paris, where there are estimated to be more rodents than people, the city authorities have transitioned from battling rats to investigating ways to peacefully coexist with them. 'No one should aim to exterminate Paris's rats and they're useful in maintaining the sewers,' the deputy mayor Anne-Claire Boux said in the lead-up to the 2024 Paris Olympics. 'The point is that they should stay in the sewers.' Research published in Urban Ecology in 2022 found rat management may be a 'wicked problem for which there is no overarching solution'. Rather than engaging in a 'war on rats', it said the focus should instead be on 'improving the overall health of the community, instead of on eliminating rats'. The study found in all major rat interventions, populations had either remained at consistent levels, or reduced dramatically and then bounced back. It also noted that they didn't just spread illnesses, but something more existential. The presence of rats, the report said, added 'anxiety and fear into the tapestry of issues that people face daily'. The black rat (Rattus rattus) and the brown or Norway rat (Rattus norvegicus) arrived in Australia with the First Fleet in the late 1700s and their numbers quickly exploded, taking to Australia's shores so naturally that some settlers thought they'd always been here. But while the invasive species would spread disease, damage buildings and agriculture, pillage bird nests and disrupt the environment, more than 60 native species of rat had already lived in Australia for up to 4m years, causing little to no harm at all. The most common native species in cities is the bush rat, a shy rodent that was the unintended victim of a campaign to exterminate black rats during a plague epidemic in the early 1900s that killed about 500 people in Australia, mostly in Sydney. Peter Banks, a conservation biology professor at the University of Sydney, says native rats could now be Australia's secret weapon against invasive species. He's among academics that have been running programs to reintroduce bush rats to areas around the Sydney harbour they once inhabited, to block reinvasion by black rats. Bush rats may look similar to invasive species but they don't cause disease. They don't smell. They live largely separate lives to humans, hidden in burrows during the day and opting for a diet of seeds, fruit and nectar instead of our trash. 'Once we removed [black rats], the bush rats would fill the area, and really dramatically reduce the black rat population,' Banks says. 'They're quite symmetrical competitors – but the black rat really doesn't like a fight. They occupy the empty spaces in the natural world and if there's something there to give them a hard time, they don't thrive. 'They're really used to living off us, so by restoring the bush, we can make it unfriendly for [invasive] rats.' However, he says, 'there's an argument to be had that the urban environment is their natural environment. We think about them as pests, and they can be pests for us, but we don't go trying to wipe out other species in their natural habitats.' For now, at least, the rats are home too – and they're here to stay.
