DAINTREE RAINFOREST CAMERA TRAPS – 2024
As a part of its long-term Daintree Rainforest Camera Trap Project, 2024 accrued 742-cassowary sightings, 460-dingoes and 4,084-feral-pigs. In terms of cumulative monthly averages, cassowary numbers decreased by 8% to 100 per-month, dingo numbers remained the same at 40 per-month and feral-pigs increased by 24% to 193 sightings per month. In comparison with 2023, cassowary numbers plummeted by 56%, dingo sightings also dropped by 54% and feral-pig numbers grew by 14%.

Intergovernmental policy requires that environmental considerations will be integrated into Government decision-making processes, ensuring that measures adopted should be cost-effective and not be disproportionate to the significance of the environmental problems being addressed. On 23rd November 2021, when the Centre for Invasive Species Solutions (CISS) released Fighting plagues and predators: Australia’s path to a pest and weed-free future, it was reported that:
“Urgent, decisive, coordinated action is crucial to stopping the spread of invasive species and to protect our extraordinary, irreplaceable native animals and plants, and Australia has a great track record in this space”.
However, the article goes on to state:
Australia has the highest rate of vertebrate mammal extinctions in the world.
In all honesty, how can Australia’s great track record protecting its extraordinary, irreplaceable native plants and animals be reconciled with the world’s highest rate of mammal extinction? Of the seventy-three species of introduced vertebrate pest roaming our continent, three have been ranked as the worst of a bad bunch; with rabbits, pigs & cats (plus an endemic plant pathogen known as Phytophthora cinnamomi) endangering more than 800 threatened species.
Feral-pigs, according to the National Threat Abatement Plan for predation, habitat degradation, competition, and disease transmission, adversely affect 148 species of threatened flora and fauna and eight threatened ecological communities. The Southern Cassowary (Casuarius casuarius johnsonii), whose habitat supports at least 106 plant and 37 animal species identified as Threatened under State and Australian Government legislation, is more particularly endangered by feral-pigs. With a more calamitous potential for consequential cascading extinctions, cassowary protection is more critically important than any other threatened species, as they are the only animal capable of distributing the seeds of more than 70 species of plant whose fruit is either too large or toxic for any other vector. Feral-pigs usurp cassowaries from habitat and resources, displace male cassowaries from their nests to devour their eggs and predate upon juvenile cassowaries. Feral-pigs also attract recreational pig-hunters who typically release large aggressive dogs and usually four at a time.
The National Feral Pig Action Plan (2021-2031), endorsed by Australia’s National Biosecurity Committee in October 2021, aims to actively suppress or eradicate Australian feral pig populations to reduce their impacts on environmental, agricultural, cultural and social assets, via a landscape-scale, nil tenure approach.
‘Nil tenure’ describes an approach where a range of control methods are applied across all tenures by all stakeholders at a regional or ‘landscape’ (rather than ‘property’) level in a cooperative and coordinated manner.
Approaching the halfway mark of the Plan’s 10-year duration, there has been no recognisable evidence of a ‘nil-tenure’ approach in the Daintree Rainforest. Indeed, the heavy formality of protective mechanisms appears only to provide unintended sanctuary to feral-pigs, along with all their catastrophic environmental and cultural degradations, across the entirety of its all-inclusive World Heritage and Endangered Ecosystem Community-listed area.
Meanwhile, dingoes kill feral-pigs and also displace them through fear of predation, but ‘nil-tenure’ seems totally annihilated by legislative definition, as dingoes are protected ‘native wildlife’ within Protected Areas, but outside these boundaries are ‘Wild Dogs’ and category 3, 4, 5 and 6 Restricted Invasive Animals under the Biosecurity Act 2014, whence they must not be moved, kept, fed, given away, sold, or released into the environment.
Any strategy that seeks to eradicate a known invasive threat, such as feral-pigs, with their high intelligence, mobility and fecundity, must acknowledge that ‘nil-tenure’ cannot be compromised and there can be no tenure exclusions whatsoever. ‘Protected Areas’ need to be apportioned as a measurable part of the pest problem and the country’s love of its Protected Areas should be encouraged, but they were never intended to provide invasive pests with effective sanctuary. We must acknowledge that extirpating Indigenous human inhabitants from traditional Country created vacancies for pests to opportunistically occupy. Placing a blanket of legislative protection over the Protected Area is what gives these invasive pests sanctuary.
Once an environmental objective has been identified, such as eradicating feral-pigs from Australia, it should be pursued in the most cost effective way, by establishing incentive structures, including market mechanisms, which enable those best placed to maximise benefits and/or minimise costs to develop their own solutions and responses to environmental problems. If the Australian Army were co-opted to provide land-holder support for coordinated feral-pigs eradication, annual flushes of seasonal fruit, such as Rambutans in North Queensland, could bring strategic support to landholders who are knowledgeable about their property’s predictable attraction to feral-pigs and because the army is already on salary, a cost-saving advantage could help those best-placed to perform more successfully.
