The "V"oice fading quickly, page-508

Totally clueless you are BB. You're ignorance is mind blowing. If you call yourself an Aussie then why have you never bothered to educate yourself regarding the aboriginals.?
Getting back to your crazy claim that they were nomadic, this is the reality. When you're so out of touch with their reeality why should anybody listen to your solutions?????

A common stereotype is that Aboriginal people were 'nomads' and never built permanent shelters. The opposite is true.An area near Portland in southwest Victoria has evidence of volcanic stone huts that date back thousands of years. [4] The Gunditjmara Aboriginal people of that area developed an 'aquacultural system' made of fish traps and weirs which is thought to be among the world's oldest, [4] covering an area of 100 square km, thus "dispelling the myth that Australia's Indigenous people were all nomadic". [5]On the opposite end of Australia, on the Dampier archipelago off Australia’s north-west coast, archeologists found evidence of stone houses dating back 9,000 years. [1] The excavation of the circular stone foundations showed occupation was maintained throughout the ice age, and evidence of human occupation dating back 21,000 years.The architecture of Aboriginal houses built prior to invasion depended on climate, natural environment, resources available, family size and particular needs of the Aboriginal nation of that area.As you can see from the image further below fire was always present around gunyas as it was used to drive away snakes and mosquitoes and other insects, as well as for cooking and heating.The Budj Bim Cultural Landscape, in Gunditjmara land in south-west Victoria, is heritage-protected and on the UNESCO's World Heritage register as "one of the world’s most extensive and oldest aquaculture systems" [6]. For more than 6,000 years Aboriginal people harvested eel, smoked and traded the fish. They built channels, weirs and dams, and there are also remnants of at least 146 stone houses, evidence that suggests Aboriginal people "settled in villages".
