Dear fly,Your questions are very good...some of them have been answered in our Thylacine eBook which can be downloaded free from this website, also the Thylacine Files which are also on this website.
We have plaster casts of thylacine footprints which are obviously not dog but which have been rejected by the 'authorities' as not dog. However, three experienced vetinarians have said they are definitely not dog.
As for sightings, these are seen as doubtful by the same 'authorities' and are taken as not proof despite how many sightings are reported in the same area. The general community has been conditioned to view people who are brave enough to report their sightings as 'loonies', hence a widespread reluctance to report sightings.
Yes, we have used a means of establishing the degree of verification of sightings using a method used by the Department of Wildlife and which was devised by this very same department. This can be seen in the Thylacine Files.
The only proof the 'authorities' will accept is the animal itself, which is against the law and could land you in gaol.
As for obtaining a video or photo, this is well nigh impossible due to the fact that the animal is hanging on by a mere thread and therefore the numbers must be very low. Also, the animal must have developed a habit of extreme elusiveness in order to survive.
To answer your question on where we would look, this is where the most sightings have occurred and also where habitat remains. Said habitat is rapidly being reduced by the clearfelling of vast tracts by Forestry Tasmania. This is condoned by our State Government.
We hope this has answered most of your questions,
Buck and Joan
