It's a very sad thing to say, but the degree of ignorance that 'white' Australians SHOW about their knowledge of our Indigenous FIRST NATION people is gob-smacking! Never, at any time in the past more than 60,000 years, have our First NATION peoples been MORE fractured to the extent that the colonizing white's have done so.
I am a member of the Wiradjuri people, the largest Nation of First Australians and despite the invading Colonizers BEST efforts to extinguish us and integrate us into their culture, we have remained. Diminished in number, but still here.
As I explained to Joydie, There's abundant evidence that our First Nation Australians FREQUENTLY gathered in places, all over this Continent, which has shocked and astounded many people, like yourself. The evidence is in locations ALL OVER AUSTRALIA, in the Rock Art, in their ORAL history which has been PROVEN to be more ACCURATE and correct than the written history from other Countries (History is written by the Victor, not the loser) , and from our First Nations traditional Celebrations. About 15 years ago, one such MEETING place was FINALLY recognised and acknowledge, near to Mt Annan, just south of Sydney.
The EVIDENCE, you ask? TREES, shrubs and various plants that were brought from locations as far North as Cape York and as far south as Melbourne. Purposefully brought to the 'Meeting Place'. Yandel'ora is the name the Dharawal people gave to Mount Annan, meaning 'place of peace between peoples'.
