The 24 representatives of The Voice will be chosen by Aborigines. They will be representative of all Aboriginal men, women, youth etc. but I'm not sure exactly which Aborigines will do the choosing.
I will vote no because although I agree that Aborigines should be listened to, and they haven't in the past because the powers that be are too arrogant, I don't think a Voice to parliament is the way to go. We do have a number of First Nations MPs, and high achievers in other fields and I think these people need to educate their own so that they will integrate properly and learn that if they want modern advantages they have to accept and respect modern culture while maintaining their own. Aboriginal languages are being revived and many place names are being dual named or changed to the original names, so they already have recognition, but here is a lot of resentment by (mostly) disadvantaged white people because Aboriginals have/had many concessions and benefits not available to whites and my fear is that this will become worse.
First Nations people (appear to) believe that they own the land and have culturally significant sites in a great many places all over the country. At any function or meeting there already has to be a Welcome to Country or Acknowledgement of Country and I believe that the Voice will be used by some (many?) to delay and control any activity that anyone wants to do. (This already happened in WA when the Heritage Act designed to protect culturally significant sites was put in place.) Aboriginal people have access to education, health, work and any benefits of western culture that they want, but many do not take full advantage of it, except perhaps the social security benefits. While many Aboriginal people have fully and successfully integrated into western society, some choose not to and/or live in remote areas, contribute very little to Australia as a whole, yet demand all the benefits of the western world. They readily consume alcohol, bought by money given to them in the form of social security and sadly this often results in children being abused, neglected and allowed to run riot, hence so much crime. A great deal of money has been given to First Nations people over the years and it has not necessarily been put to best use and many projects intended to improve the lives of Aboriginal people have failed, and I think the Voice will not really make a positive difference.
