Worthy this week features one man who has dedicated the past 15 years to tracking and searching for one of Australia's most fascinating and extinct marsupials - the elusive Thylacine.

He claims he has spotted the mysterious Tasmanian Tiger at least 20 times during his career, and believes it is only a matter of time before there is indisputable evidence that will prove once and for all, that the Tasmanian Tiger is very much alive.

We discuss the reasons behind the extinction of this animal in the late 1930's and where this wolf-and-tiger-like marsupial could be, if it is indeed alive somewhere Down Under.
