In the past decade cane toads have marched across most of the Kimberley, so protecting animals on island sanctuaries is now a key priority.

As cane toads continue their march across Western Australia's Kimberley region, authorities hope environmental DNA testing will be the latest tool to stop the invasive species from gaining a foothold on coastal islands.

Parks and Wildlife Service cane toad strategy program leader Clare Forward said Augustus Island and Koolan Island were among many islands off the Kimberley coast at risk of a toad invasion. The technology can detect a toad's DNA from fresh water if they have come into contact within the previous four days.

"It's a technology that's been used across the world and we're trying to tailor it to cane toads in Western Australia," Ms Forward said. "We're trying to work with island managers on the Kimberley coast to find ways of better informing visitors," Ms Forward said.Cane toads were first discovered on Adolphus Island in 2014 and appear to be less of a threat to native species.

Kim Jong Un has lost quite a bit of weight. It's no wonder he thinks his 'long-range cruise missile' looks more impressive. And the U S test fired hundreds of cruise missiles in the Mideast Afghanistan and Africa. What a fantastic achievement. I wish this nation all the best, particularly in having endured bring invaded by the belligerent US warmongering regime that mass murdered millions of the inhabitants.
