This is true. But when you plot the distribution of these families
something strange emerges.

1. All the language families are present in the North of Australia
(corresponding an area between the Western Australian Kimberley
across the top of the Northern Territory, to Carpentaria and Cape
York.

2. Only one language family - the Pama Nyungan - is found across the
remaining 80% of Australia.

Despite the differences between families, there is a clear connection
by means of phonemes.

In Aboriginal Languages
There are no *s, *h, *f or *v

The phonemes *t and *d are identical
The phonemes *g and *k are identical
The phonemes *p and *b are identical

This is true of all language families.
