NSW inquiry weighs the 'wild dogs' category that governs dingo control in national parks
Under New South Wales law dingoes are unprotected and managed as wild dogs. The parliamentary inquiry now weighing nearly 400 submissions has thin evidence that the standard control method protects livestock.

What happened
- Conventional practice is indiscriminate killing, mostly large-scale baiting programs aimed at areas where dingoes are known to take livestock.
- In one study cited in the debate, baiting across four cattle ranches lowered the relative abundance of dingoes without lowering the number of calves lost.
- Public hearings have concluded, and the inquiry is now working through what an alternative approach to dingo management could look like.

Why it matters
- decision The category decides what park staff are doing when they bait: suppressing a declared pest or killing protected native wildlife. Changing that description requires separate policy decisions on native status, park protection and research funding.
- constraint An inquiry choosing between methods is working without an effect size for livestock losses, the outcome graziers are measured on. The cited evidence measures predator abundance well and livestock survival poorly.
- cost Nonlethal control moves the bill from bait programs to capital works and animal training, and those costs land on the landholders bordering parks unless the state carries them.
- exposure Sheep and goat producers next to protected land absorb the losses if a new method underperforms, and losses on those enterprises run to thousands of dollars in forgone income.
Baiting reduces the number of dingoes in an area, and whether it reduces the number of dead livestock is a separate measurement. In the study cited by the analysis Phys.org republished from The Conversation the two came apart: across four cattle ranches, baiting cut the relative abundance of dingoes and left the number of calves lost unchanged [6][18].
Four properties is a small denominator, and the article leaves the study, its authors and its design unnamed [19]. The cattle setting also sits to one side of the conflict the same article describes as sharpest, which is on farms running sheep and goats, where dingoes attack, maim and kill stock and can cost a farmer thousands of dollars in lost income [12].
The article offers a reason the two measures diverge. Baiting's effect on dingo numbers can be short-lived, and a reduced population does not necessarily protect livestock from unexpected attacks [8]. On the broader question it is blunt: there is little evidence that indiscriminate killing, the conventional approach, actually protects livestock [5][7].
The legal question runs alongside the empirical one. NSW law leaves dingoes unprotected and manages them inside the category of wild dogs, a term that includes them [2]. The inquiry is examining their genetic status together with their ecological role and cultural significance, and has received nearly 400 public submissions [3][4]. Reclassification on its own would leave practice on the ground where it is. The article's position is that recognising dingoes as a native species, protecting them within national parks, and funding the research needed to understand coexistence each require major policy change [11].
The alternatives under discussion mostly apply to the land next door. Exclusion fencing, guardian animals and targeted responses to individual problem animals are put forward for properties bordering national parks [9], while the protection decision applies inside them [1]. The article calls the high costs of fencing and of training guardian animals major hurdles to doing this at scale [10].
The state's stated values for its parks include protecting biodiversity, keeping ecosystems intact and upholding the values of local First Nations communities, balanced against research and sustainable tourism [14]. Dingoes touch several of those at once. The ecological case rests on their role as a top predator holding down kangaroos, foxes and other invasive species [16]; the cultural case rests on archaeological evidence of a long relationship with Indigenous Australians and their continuing significance as a native animal to First Nations communities [17]. Harder to weigh is the psychological toll on farmers of losing animals and worrying about the next attack [13].
What the inquiry has in front of it is submissions and hearing evidence [4]. A comparison of baiting against fencing and guardian animals, scored on livestock losses rather than on predator counts, would be a different exercise, and none appears in the evidence cited so far. Public hearings have concluded and the inquiry is now considering what an alternative approach could look like [15].
What to watch
- Whether the inquiry's report recommends moving dingoes out of the 'wild dogs' category in NSW law.
- Any funded comparison of baiting against fencing and guardian animals on sheep and goat properties, scored on livestock losses.
- Whether a recommendation for nonlethal control arrives with money attached for fencing and guardian animal training.
