A Queensland disability pensioner with a love of dingoes has begun a personal crusade to save the animals from extinction in the wild.

Simon Stretton is battling biosecurity regulations and opposition from farmers as he tries to create a reservoir of purebred dingo genes to preserve wild populations.

Mr Stretton, who calls himself "Dingo Simon", has started his own sanctuary at Durong in the state's South Burnett region.

"What I'm trying to do is save dingoes from extinction, basically, due to interbreeding from the wild dogs [and] also from the State Government's excessive use of 1080 baiting," he said.

The dingo is considered to be a pest in Queensland.

Mr Stretton said he had faced a range of restrictions and difficulties in keeping and breeding his 18 animals, which include different types of dingoes from around Australia.

Fraser Island population of particular concern to 'Dingo Simon'

Mr Stretton was particularly concerned about the Fraser Island dingo population.

He believes the State Government's management measures, which include culling problem animals, were putting the dingoes at risk of inbreeding.

"The numbers are down that low that we've unfortunately got sibling breeding," Mr Stretton said.

"Brothers and sisters are breeding with each other and we've got a downward spiral towards extinction.

"I'd like to stop this now."

Mr Stretton has bred pups from a dingo he believes was illegally removed from the island, and hopes to one day reintroduce the animals to Fraser.

"Every now and then you have to bring in new bloodlines," Mr Stretton said.

"I would be overwhelmed if it was allowed that one of the dingoes from my sanctuary here would be allowed to be taken over to Fraser Island under a specified breeding program, to improve the bloodstock on the island."

However, the State Government does not support the plan.

"In-breeding has not been identified as a risk to the Fraser Island dingo population, and like all native species on the island, the dingo population is being left to manage itself," the Department of Environment and Heritage said in a statement.

"The external review of the Fraser Island Dingo Management Strategy in 2012 did not support the introduction of new dingo genetics to Fraser Island, and the department has seen no evidence that Mr Stretton's dingoes are bred from a rescued Fraser Island dingo."

Decline in dingoes 'catastrophic' for native animals and plants

University of New South Wales researcher Deborah Rose, who has written about the role of dingoes in preserving and restoring ecosystems, had visited Mr Stretton's sanctuary.

"To have a population reservoir like what Simon is doing means that there are dingoes who have the capacity to live the way dingoes are meant to live," Professor Rose said.

She said dingoes were threatened by both interbreeding and wild dog control measures, and warned their decline would be catastrophic for other native animals and plants.

"What's really worrying is the functional cascade - we call it 'functional extinction' - where an animal is no longer able to do the ecological work that evolution put it in place to do.

"That's where dingoes really are at risk.

"They're a top predator, a keystone species, they hold whole ecosystems together and when they are no longer able to live in the wild in their own way of life, then you start to see the extinction cascade."

Mr Stretton recently breached his permit conditions when one of his female dingoes had a litter of pups and he now had to build new enclosures and desex some of his animals.

He was trying to raise $10,000 to pay for the building work, and said it would help him secure the species and the sanctuary for the long-term.

"The genetics we have here are extremely valuable and to get community support would be awesome," Mr Stretton said.
