'Sightings' of extinct Tasmanian tiger prompt search in Queensland

Eyewitness accounts of large, dog-like animals in state's far north spur scientific hunt for thylacines, thought to have died out in 1936

"Plausible" possible sightings of a Tasmanian tiger in north Queensland have prompted scientists to undertake a search for the species thought to have died out more than 80 years ago.

The last thylacine is thought to have died in Hobart zoo in 1936, and it is widely believed to have become extinct on mainland Australia at least 2,000 years ago.
