Imagine a serene botanic garden, a sanctuary for native wildlife, suddenly overrun by a toxic invader. That's exactly what happened at Darwin's George Brown Botanic Gardens, where over 1,000 cane toads were recently captured in the first major bust in over a decade. But here's where it gets even more alarming: these toads aren't just a nuisance—they're a deadly threat to local animals and pets. On a rainy Tuesday night, more than 90 dedicated volunteers braved the downpour to comb the gardens, the city's only botanical haven, in search of these invasive pests. While 'toad busts' are a common wet-season activity in some parts of the Top End, the gardens hadn't seen one in over 10 years, making this event both rare and crucial.
And this is the part most people miss: the gardens, with their year-round irrigation and numerous ponds, provide the perfect breeding ground for cane toads. Ben Lui, the gardens' director, explains, 'We have a thriving ecosystem here with native lizards and snakes, but the toads pose a fatal risk to them—and to the dogs that visitors bring in.' The toads' ability to reproduce rapidly within the gardens means they can easily spread into surrounding areas, endangering pets and wildlife alike. What makes cane toads so dangerous? They carry two glands that secrete a potent toxin, which can be lethal to small animals if ingested.
The scale of the problem became glaringly apparent during the bust. 'We had no idea how many toads we'd find after so many years,' Mr. Lui admitted. 'We guessed a few hundred, but the final count exceeded 1,000.' Among the catches, the heaviest toad weighed nearly 300 grams. The Mitchell family, seasoned toad-busting veterans, took home the prize for capturing the most toads in one night—an astonishing 353. Joel Mitchell described the chaos: 'My kids had buckets overflowing with toads, and my wife Jen was struggling to add more—they were literally flying out!' Despite the frenzy, the Mitchells emphasized the importance of such events, especially in urban green spaces like the botanic gardens.
Here’s the controversial part: while many wet-season toad busts occur in rural Darwin, Joel Mitchell argues that more efforts are needed in urban areas. 'These green belts are being overrun, and it’s devastating local wildlife,' he said, pointing to a nearby park where frilled-neck lizards have been 'decimated' by the toads. For Jenny Mitchell, the event was also a chance for quality family time. 'My teenagers are passionate about nature, and this was a rare opportunity to connect outdoors,' she shared. The captured toads will be humanely euthanized in fridges and freezers before being sent to a local taxidermist.
But here’s the question that lingers: Are we doing enough to combat the spread of cane toads in urban ecosystems? With their rapid reproduction and deadly toxin, these invaders pose a growing threat to Australia’s native wildlife and domestic pets. Should more resources be allocated to urban toad-busting events, or is the focus better placed on rural areas? Let us know your thoughts in the comments—this is a conversation that needs your voice.
