Cryptids of Australia pt:1 & pt:2

[BIAD]

Britannica.com states:

 'Some 180 million years ago, in the Jurassic Period, the western half of Gondwana (Africa and South America) separated
from the eastern half (Madagascar, India, Australia, and Antarctica).'

Britannica.com also states:

'Human evolution, the process by which human beings developed on Earth from now-extinct primates.
Viewed zoologically, we humans are Homo sapiens, a culture-bearing upright-walking species that lives on the ground and very
likely first evolved in Africa about 315,000 years ago.

We are now the only living members of what many zoologists refer to as the human tribe, Hominini, but there is abundant fossil
evidence to indicate that we were preceded for millions of years by other hominins, such as Ardipithecus, Australopithecus, and
other species of Homo, and that our species also lived for a time contemporaneously with at least one other member of our genus,
H. neanderthalensis (the Neanderthals)....'

So if the Yowie exists, it had to have 'left Africa' before the Australia we know today had split from Gondwana -a piece of Pangaea.
This is a puzzle!
