The Department of Environment and Conservation has blocked efforts to stop cane toads spreading through the world heritage-listed Bungle Bungles, according to the volunteers leading the fight against the amphibians.
Ben Scott-Virtue from Kimberley Toad Busters said the DEC had restricted access to Purnululu National Park, letting the toads "run through unchecked".
"The DEC are stonewalling us and making us stay on the tourist tracks, which cover about 5 per cent of the range," he said. "We've been trying to gain access from the DEC for years but haven't been able to.
"The Bungles have gone under without a sufficient management strategy from the DEC.
"It's hard to believe."
Mr Scott-Virtue said that although it was too late for the Bungle Bungles, there was an opportunity to stop the cane toads reaching the Fitzroy catchment area.
After an unsuccessful Royalties for Regions submission last year, Mr Scott-Virtue said more funding was needed to protect the Kimberley.
"They're only a hop, step and a jump from the Ord Catchment area, then two hills away from the Fitzroy Catchment area," he said. "Once that happens, the Kimberley will be colonised extremely quickly. We know we've mitigated the impact of toads on Kununurra.
"We just need more funding to put more people on the ground."
Environment Minister Bill Marmion confirmed cane toads had reached Purnululu National Park "in low numbers".
He said the DEC would install drop-off boxes at the campgrounds so tourists could help remove the toads.
"The DEC has provided KTB with permits to enter the national park that have standard conditions of entry, including that all-terrain vehicles are to remain on designated tracks," he said. "As identified in the Cane Toad Strategy for WA 2009-19, there is no way of stopping cane toads.
"The DEC is continuing to work with scientists to investigate new techniques for reducing the impact of cane toads on native fauna."
Kim Hands, from Perth organisation Stop the Toad, said she believed the State Government had put cane toads in the "too-hard basket".'We just need more funding to put more people on the ground.' " Toad Busters' *Ben Scott-Virtue *
