Feel free to accept or reject as you wish. I only will state that in 1989 I was with a small group of people in the NW area of Tasmania, and believe we saw what may have been the animal described on your website.I do not remember the exact location. All I can tell you is that I remember that it had been raining (which it did often during our visit) and there was a sort of ground mist. It was quite cold. The sighting took place in the early morning, it was not fully daylight, but we did clearly see this animal.
The best description I could give of the surrounding area is "ferny", as this is what I remember most the ferns and their strong smell, there were many tall trees, also however and some smaller trees. This was not too far from the road, sorry can't say which road. I can say that I don't remember seeing electricity poles (but there may have been some).
It was a long way from "civilization". Anyway, here is what happened:
We were walking along, making quite a bit of noise, chattering and so on. We did not expect to see animals but hoped to maybe see a kangaroo if we were lucky.
We came to a semi-cleared area (with ferns and trees). There was a lot of debris on the ground. We saw an animal but did not realize the significance of this sighting. It looked like a cross between a dog and a kangaroo to us, and we did not know this should be reported or whatever.
It had a kangaroo tail, dog-like body, fox-like ears. Best description of color would be 'chocolate milk'. Stripes were darker but did not look 'solid'.
It kind of paused for a moment like we had caught it in the middle of something it shouldn't have been doing. Then it left the scene.
That's really all that happened. There was a woman with us who had a camera but she did not think to take a picture of the animal until it was too late.
Even afterwards we had no idea that this was significant. The only reason I am writing this at all is because I want to let you know that there had been a possible sighting in an area other than that mentioned in other parts of your site.
I do not seek fame. I have asked a friend to forward this message. I have told all that I know, so please do not e-mail requesting more information or telling me that you believe or do not believe the story or whatever. This is ALL THAT I KNOW. I am not familiar with Tasmanian animals or geography except that it was north-west part of the state. So I cannot provide any more info.
