The Voice to Parliament is a referendum that'll recognise Aboriginal and Torres Strait Islander peoples in the Constitution through an Aboriginal and Torres Strait Islander Voice.
The Voice will be an independent, representative advisory body for First Nations peoples. It will provide a permanent means to advise the Australian Parliament and Government on the views of Aboriginal and Torres Strait Islander peoples on matters that affect them.
I doubt this would mean more taxes and so what, taxes are only getting lower and lower, to which our healthcare system is getting worse and worse because bulk billing is becoming harder to find.
This is actually going to give more freedom because I believe the Voice to Parliament is the only way to get a treaty as there would be more Aboriginal rights given as they don't have enough rights.
And bigger government. Well Labor is already trying to make a bigger government than what the coalition had, to which there was even price caps introduced to regulate power prices through setting a limit on the prices that a utility provider can charge.
