One of Australia's most celebrated authors, Tim Winton, has thrown his support behind the Indigenous Voice to Parliament.

Mr Winton joins a host of writers, musicians and artists who have shown their support for constitutional change at the upcoming referendum on an Indigenous Voice to Parliament on October 14.

"The Uluru Statement from the Heart, a work of deep reflection and extensive consultation within Aboriginal communities, is a generous gift to our nation," Mr Winton wrote on social media on Monday.

"But it's also a compelling plea for our First Peoples to be seen and properly listened to. It's an opportunity for all of us – Indigenous, native-born and immigrant – to go forward together in a new spirit of respect, honesty and hope.

"For something better. To do better. To be better. And to produce better outcomes for those in our midst whose lives are so often constrained, deformed, devalued and cut short because of trauma, exclusion and the ignorance of others."

The acclaimed author and conservationist, who has won four Miles Franklin Awards and been shortlisted for the prestigious Booker Prize twice said he stood with those who've asked us to listen.

"And to their offer of unity, and their plea for a Voice that reflects their expertise, their experience and their ideas, I say yes. From the head and from the heart. Yes!"

Tens of thousands of people attended 'Walk for Yes' rallies around the country over the weekend.

Yes and No campaigners have exchanged verbal blows, with Indigenous Australians minister Linda Burney shocked at No campaigner Senator Jacinta Nampijinpa Price's latest comments on the legacy of colonialism.

After her National Press Gallery speech, Senator Price was asked if colonialism had ongoing negative effects in Australia.

"I'll be honest with you, no, I don't think so. Positive impact? Absolutely," she replied.

Minister Burney hit back, labelling Senator Price's claims a "betrayal".
