Warning: Name of deceased First Nations man mentioned.
All Australians have a chance to recognise the Voice of traditional  owners, the
custodians of country for 65,000 years. There are already many advisory bodies
to Parliament, and this would also be one of them. For those who are frightened of change, change happened in 1788 - for the people already living here. For those who feel this referendum doesn't go far enough - this will be the first step towards equal Voice in a Treaty: a formal written agreement.

The Voice is needed until discrimination is no more; it is needed until the First Nations truth-telling has as strong a place as the colonial history; it is needed until First Nations people become truly of equal standing, with equal opportunities, and safety.
The Voice is not new. 1938 a petition for recognition was sent to Parliament after William Cooper first started advocating in 1933, and established the Australian Aborigines' League.
