It is commonly accepted that the dingo arrived in Australia approximately 4,000 years ago, and that the current population of dingoes across Australia grew from just one pregnant female. However, this was just an hypothesis posited by geneticist Dr Alan Wilton (deceased), and was never meant to be taken as fact. In the last paper he wrote before he died, Dr Wilton suggested that dingoes were more likely to have been introduced some 11,000 – 18,000 years ago . In a recent genetics study, Dr Wilton’s partner, Dr Kylie Cairns found that there were most likely two introductions of dingoes to Australia, not just one . One introduction was to the North-west of the country, and the other was to the South-east.
It is also commonly thought that dingoes were brought to Australia by Asian seafarers, but another hypothesis is that dingoes spread into what is now Australia via the land bridge between Papua New Guinea and Australia, some 8,000 years ago. Dingoes were declared indigenous to Australia in 1992 and are protected under legislation. However, they are also classified as a pest animal due to their predation on livestock, and with varying legislation in each state, the complexities of protecting them as a native taxon can be very frustrating.
Current taxonomy classifies the dingo as a subspecies of Canis lupus (wolf) that is, Canis lupus dingo . However, the classification Canis dingo was proposed in a 2014 study that established a reference description of the dingo based on pre-20th century specimens that are unlikely to have been influenced by hybridisation.  Dingoes are now, therefore, increasingly considered a species in their own right. However, current methods of identifying dingoes are inadequate because natural variation within dingo populations is poorly understood. Skull morphology and DNA testing techniques are not reliable. Geneticist, Dr Alan Wilton, who developed the current dingo purity test, stipulated that dingoes which test between 75 and 100 per cent pure should be treated as ‘pure’ for the purposes of conservation in the wild. In addition, there is considerable differentiation in the colour of dingoes including numerous combinations of white, ginger, black, and black and tan. Most people expect dingoes to be ginger and deem anything of a different colour to be hybrid.
Hybridisation of dingoes is said to be the biggest threat to their survival. However there is little evidence that moderately hibridised dingoes are dangerous to the environment. In fact, the opposite seems to be the case. Most all modern dingoes will have some genetic dog markers, but they behave and act like dingoes. Dingoes howl instead of barking, reproduce only once a year, and live in stable packs. It is only when these packs are fractured due to lethal control that hybridisation becomes more likely. A stable pack contains an alpha male and female, and offspring from the previous year plus pups. The alpha male and female suppress breeding by subordinate pack members, . Dingoes can suppress breeding altogether in times of drought, fire, or when food is low for any other reason. A domestic dog would have a great deal of trouble infiltrating a stable dingo pack. However, if, due to lethal control, the pack is fractured, then the subordinate members would be more likely to mate with domestic dogs, thus creating a situation where there are more dingoes, not less. With no stable pack to teach the new parents and pups how to behave and what to hunt, they become like unruly teenagers and run amok, hunting anything and everything indiscriminately. Subsequently, the use of lethal control causes more problems than it solves.
Dingoes are territorial and are formidable in protecting their territories from intruders. Dingoes will only take farm stock if there is a shortage of natural food, and studies have shown that despite the fact that dingoes are regarded as predators of sheep and cattle, domestic livestock do not comprise a significant part of foods eaten. 
Stable dingo packs, therefore, offer a level of protection to farms from intruders such as free-ranging domestic dogs which are known to attack stock at will, not with the intention of eating what they kill, but killing without purpose. When a pack is fractured, these domestic dogs, which form into packs at night, predate on stock animals. Pastoralists who do not use lethal control on their properties find that they have less stock predation than those who do. 
Even so, there is little chance that severely hybridised offspring would survive in the wild. Without the characteristics of the dingo which are tailored to Australia’s harsh environment, hybrids would die out quickly. If they manage to survive and reproduce, eventually, after several generations, the genetics revert back to the ancestral dingo form.
Herein lies a conservation dilemma: some dingo conservationists want to preserve only pure dingoes, while others want to conserve dingo hybrids as well. There is a growing body of evidence which suggests that protecting dingo hybrids is beneficial for the environment as long as they are performing their role as top-order predator, protecting our native animals from introduced species like feral cats, foxes, pigs, goats and deer. They also keep native animals such as kangaroos at bay, which left unchecked, can cause just as many if not more problems for farmers as the dingoes themselves, by eating pasture grass and drinking stock water.
Dingoes are protected in national parks; however the same national parks are baited with sodium monofluoroacetate(1080 poison) to control foxes, paradoxically making national parks extremely hostile places for our top-order predator to live. This bait is indiscriminate and cruel, and not only kills foxes, but of course, dingoes, as well as other non-target animals like the endangered quoll, birds of prey, goannas and any carrion-eating animal. 1080 is said to be harmless to the environment because it is derived from native plants, but the bait is a synthetic substance which our native animals have no tolerance for. There is no antidote. 1080 can stay active in the environment, polluting waterways and flora, for 12 months or more. Again, baiting has the capacity to destroy dingo pack structure and cause social dysfunction within dingo populations, in turn undermining their ecosystem function. Despite unrelenting baiting, farmers are finding that they still have problems with dingoes. Efforts to eradicate dingoes are not working. Predator-friendly farming should be the way of the future.
Australia is the only country where its top-order predator is not safe anywhere.
Some states of Australia have a ‘wild dog’ bounty system in place, paying up to $120 per dingo scalp. Bounties have been found to be ineffective at reducing dingo numbers (or foxes or whatever else is targeted).
In a recent media release (17 Nov 2016) The Wilderness Society stated:
Previously, dingoes and wild dogs were targeted strategically, in areas where farmers were experiencing stock loss problems.
In contrast, the bounty system applies to very large areas – over half of the relevant public land in eastern Victoria is subject to the bounty – regardless of whether livestock protection is required.
The key issues are poorly informed members of the public unnecessarily killing dingoes and dingo hybrids, and the subsequent disruption of pack structures - believed to result in changes to territorial boundaries, and the increased risk of hybridisation and stock loss.
Lost in all of this is the importance the dingo holds for the Aboriginal First Nations People. Irrespective of when and how the dingo came to Australia, it was immediately adopted by the Aboriginal people and took on an important role in their lives. It is speculated that dingoes helped with hunting, but this sometimes questioned. We do know that the Aboriginal people were very fond of their dingoes; women nursed them from their own breasts as puppies, or expressed milk for them; when the adults went hunting, dingoes were left behind at camp to look after the children, keeping them safe from both evil spirits, and more corporeal dangers, like snakes and other intruders. Dingoes were often carried on walkabout, and were objects of great affection. In some tribes, dingoes were a totem animal; sacred. If a dingo was harmed in any way, punishment was often death. When a person died, often times his dingo companion was buried with him. 
The Aboriginal people have practically no voice in the ‘dingo: friend or foe’ debate, except perhaps on Fraser Island where they have stated that the white people first tried to eradicate them, and now they are trying to eradicate their dog.
‘They had us leave this Country, removed us, and it looks like they want to remove the dingoes. It is history repeating itself, only [now] it is the dingoes, which is part of our life. When the dingo is endangered, we feel like part of our culture is endangered.’ 
The dingo has always been an ancient semi-domesticate animal, living symbiotically with the Aboriginal people and up until recently, in places on Fraser Island, with white Australians. For the most part today the dingo is elusive, but historically dingoes often befriended wandering swaggies or cattlemen on their journeys across the country or around their properties.
So how do we save the dingoes? The National Dingo Preservation and Recovery Program Inc (NDPRP) is currently focusing its energies on two places: Victoria, in the hope we can set precedents there, which we can then lobby other states with; and Fraser Island in Queensland because of the impending extinction of the iconic Fraser Island dingo which has its own unique characteristics.
The members of the NDPRP were instrumental in having the dingo listed as a threatened species in Victoria, under the Flora and Fauna Guarantee Act. Although protections are in place for ‘pure’ dingoes under this Act, those protections are currently being undermined by the influence of two fishers and hunters members in the Victorian Legislative Council, who exercise disproportionate influence over the Victorian government. It is this influence which explains the recent reintroduction of a ‘wild dog’ bounty in Victoria despite Victoria having been the first state to list the dingo as threatened.
Over the past two decades or so, a body of research evidence has grown, which shows that stable, healthy dingo populations have a net beneficial effect upon ecosystem stability. This research coincided with a growing international focus on the importance of apex predators for ecosystem maintenance and presented a direct challenge to entrenched anti-dingo prejudice in Australia. More recently, there has been a concerted counter-reaction from extreme elements within the pastoral lobby in an attempt to discredit earlier apex predator research findings and to reassert anti-dingo dogma.
In collaboration with the Humane Society International, the Wilderness Society, the Australian Wildlife Protection Council, Save Fraser Island Dingoes, Eagle’s Nest Wildlife Sanctuary, scientists, and other groups, we are constantly lobbying for legislative change on a number of issues, the main two being 1/ to broaden the definition of the dingo, and 2/ to cease lethal control, or limit areas where it is deployed.
Other measures to protect livestock have been shown to be very effective, including the use of Maremma guard dogs. Financial compensation for stock loss might also be tried. The cost of lethal control would far outweigh the cost of reimbursing farmers for stock loss.
The most effective form of dingo control however, would be to leave dingoes alone, stop lethal control altogether, and let the ecosystem recover.
