Thylacine
Sailors on Abel Tasman's ship in November 1642 reported seeing "tiger" footprints.  The French explorer, Antoine Bruni d'Entrecasteaux, found a thylacine jaw bone in 1792. On May 13, 1792, he made the first confirmed sighting, which was described as being the size of a large dog, streaked with black. In 1805, Lieutenant Governor Paterson sent a description of a thylacine to Sydney. He said the animal was rare and uncommon.
