We have uploaded some videos on YouTube. This is being used as evidence that Cairns Regional Council is dispersing the Spectacled Flying Foxes (SFFs), not deterring them as they claim (once they land in the trees, it is no longer ‘deterrence’, it is ‘dispersal’. But even if Cairns Regional Council were just deterring, this is largely irrelevant. If there are significantly pregnant females, all dispersal and deterrence activities must stop. Any SFF expert will tell you it is very likely a significant number of adult females are now signficantly pregnant.
Stop the dispersal-deterrence-eviction now!

Yet, the federal environment minister approved the dispersal last month under the Environment Protection and Biodiversity Conservation Act (EPBC Act) — Australia’s key environment legislation for protecting threatened species, and currently under a ten-year review.
Today, the camp is not only home to a big portion of the species, but also around 2,000 pups each year. Flying-foxes are extremely mobile in the region, so the camp provides a roosting habitat for more than what’s present at any one time.
Why dispersals don’t work
The council is permitted to disperse the flying-foxes with deterrent measures, including pyrotechnics, intense lighting, acoustic devices and other non-lethal means.
The Conversation sought a response to this article from Cairns Regional Council. A spokesperson said:
Relocation measures will only occur between May and September — outside of the spectacled flying fox pup rearing season to avoid a disruption to the species’ breeding cycle.
The relocation activity will be undertaken by appropriately qualified and experienced individuals and non-lethal methods will be used.
The program is tailored to minimise any stress on the animals and causes no injury of any type.
Dispersals risk stressing the already disturbed animals, and causing injuries and even abortions and other fatalities. They also risk shifting the issues to other parts of our human communities, as the bats tend to end up settling in an unanticipated location after having been shuffled around town like a game of musical chairs.
Cairns Regional Council argues their decision to attempt to move the bats to the Cairns Central Swamp is in the long-term interest of their survival. A council spokesperson says:
Heat stress events, urban development and increased construction in close proximity to the Cairns City Library roost will continue to stress and adversely affect the spectacled flying fox population.
Also, the health of roost trees at the library site, and therefore the viability of the site as a spectacled flying fox roost, is diminishing. Council believes relocation will mitigate human/flying fox conflict, enable the trees at the library to recover, and will likely reduce the high rates of pup mortality that have been recorded at the library colony.
But these animal welfare concerns arose from the accumulated impacts of the council’s poor management actions, or actions the council supported.
In 2014, the council was found guilty, under the Queensland Nature Conservation Act, of driving away spectacled flying-foxes and illegally pruning the habitat trees.
The Cairns camp was then subjected to a series of EPBC-approved roost tree removals in 2014, 2015, 2016 and 2017. Collectively these destroyed more than two-thirds of the available roosting habitat at the site.
This directly contradicts the specific EPBC Act referral guideline, which states actions to manage the flying-fox camps should not significantly impact the species.
And in 2015, Cairns Aquarium developers had to destroy trees home to hundreds of spectacled flying-foxes before they could start construction. That’s because under the EPBC Act, no building near or around the flying-foxes is permitted. In this case, the act’s well-intentioned protection measures caused far more harm than good.
Warnings fall on deaf ears
In the meantime, the national conservation status of the spectacled flying-fox moved too slowly from “vulnerable” to “endangered” in the listing process.
What’s more, the state government’s recovery plan for the spectacled flying-fox — in place since 2010 — has never been implemented.
Are there any solutions?
There are no solutions under the EPBC Act as it’s currently framed.
The tragic end to the story is that a dangerous precedent is being set for flying-fox management in Australia. Bat carers in Cairns are readying themselves for an influx of casualties from the dispersal.
Some bat carers have sadly reached the conclusion the dispersal is now the least-bad option for the bats after their stronghold suffered a death by a thousand cuts, leaving their home unviable.
