Palynological evidence from South Eastern Australia suggests an increase in fire activity dating from around 120,000 years ago.This has been interpreted as representing human activity, but the dating of the evidence has been strongly challenged.Scott Cane wrote in 2013 that the first wave may have been prompted by the eruption of Mount Toba and if they arrived around 70,000 years ago could have crossed the water from Timor, when the sea level was low - but if they came later, around 50,000 years ago, a more likely route would be through the Moluccas to New Guinea.Given that the likely landfall regions have been under around 50 metres of water for the last 15,000 years, it is unlikely that the timing will ever be established with certainty.All told, about 60 different vertebrates became extinct, including the Diprotodon family (very large marsupial herbivores that looked rather like hippos), several large flightless birds, carnivorous kangaroos, Wonambi naracoortensis, a 5-metre snake, a five-metre lizard and Meiolania, a tortoise the size of a small car.The direct cause of the mass extinctions is uncertain: it may have been fire, hunting, climate change or a combination of all or any of these factors, although the rapid decline of many species is still a matter of dispute.
By 9,000 years ago small islands in Bass Strait, as well as Kangaroo Island were no longer inhabited.
It was the first time any human had managed to leave the Afro-Asian ecological system." The earliest evidence of humans in Australia is at least 65,000 years old.
