Tasmanian tiger sightings: 'I represent 3,000 people who have been told they’re nuts'

The Thylacine Awareness Group is 'dedicated to the research, recognition and conservation of our most elusive apex predator' - officially extinct since 1936

Six years ago Neil Waters moved to Tasmania. There, he says, he had a "brief encounter" with a thylacine, the carnivorous marsupial known as the Tasmanian tiger, declared extinct in 1986.

Two years later, in January 2014, he was doing work on his house when a smaller animal walked up a dirt track leading out of a tin mine and past his bedroom window.
