How long has dingoes been in Australia?

It would seem that they came to Australia with seafaring Asians. Scientists have dated a skeleton at 3500years, but believe the dingoes may have been here 3500 - 10,000 years. We know the aboriginal people have been here 40,000 -60,000 years, and 'domesticated' some dingoes, which the men took with them when hunting.
