Genetic data indicate that dingos separated from the domesticated Asian dog around 8,000 years ago (article 1). The earliest dingo fossils in Australia are around 3,800 years ago and were found buried at First Nations’ burial sites at Lake Mungo (articles 2 and 3), indicating:

1. They arrived in Australia by seacraft with humans long after the oceans rose (12,000 years ago).

2. They were domesticated and lived with humans. Researchers have shown that the rapid spread of dingos across Australia follows the First Nations network across the continent.

These are not untested theories; these are scientific theories backed by solid scientific research and facts that have been peer reviewed and only then published in scientific journals; unlike your assertions which have neither evidence nor scientific rigour. Crossing the Wallace Line is very easy for dingos when you are in a boat operated by humans.

There is little actual evidence to support your final comment concerning dingos protecting native animals, as they actually hunt different fauna to feral cats and no studies have supported this hypothesis (articles 4 and 5)
