Authorities plan to enlist sniffer dogs as their latest tool in the fight against the spread of cane toads.
The system will be trialled at the Western Australia-Northern Territory border.
It is believed to be the first time that sniffer dogs have been used to detect cane toads.
But Gordon Wyre of the Department of Conservation and Land Management says they have already proven effective in a similar area.
"We think it might be worth a shot because they actually had a successful program going in Queensland for a couple of years with a dog called Angus sniffing out an introduced turtle species called the red-eared slider," he said.
The department expects to finalise a contract soon for a company to provide a trial dog, probably a labrador or beagle, to be based in Kununurra, in WA's north.
If successful, more dogs will be added to the team, checking vehicles at the border and helping volunteers trap the toads in the Territory.
