... dingos look like Asiatic Wild Dog especially the Dhole
well thats what I think

I think they are actually the same dog. I thought I saw a documentary about this once.
It would make sense if you agree that man came to Australia through Asia, and hopped across the islands. Apparently dogs were traded across this same route, but relatively recently.
It is interesting (to me at least) that along the island chains they can find evidence of pigs being traded (well eaten actually

), but at some point they stop and seem to not have made it to mainland Australia.
