Haha ......................speaking of Thylacines, there have been reports of sightings in Southern Australia over the last decade or so & although the video & photo evidence is a little ' unclonclusive' the witness reports, scats & tracks are relatively believable,(certainly more so that the reports of big cats in the UK) there has even been been some scat & fur DNA'd & although & few private labatories have positively ID them as Thylacine, the state run labs have concluded it is dog..
Without getting into conspiracy theories & government cover-ups...............should the Thylacine be declared no longer extinct & because it would be a protected species,large areas of land would have to be set aside for it's presevation as well as goverment money for it's protection. Needless to say, there are quite a few influencial people who would prefer it didn't happen.
It 's a nice to imagine though that there were some specimens that survived the massacre & that their descendants are roaming the Aussie hills.
