The Chamber of Arts and Culture Western Australia has joined a long line of clubs and organisations that have thrown their support behind the First Nations Voice to Parliament.
"As the state-wide organisation for Arts and Culture in WA we strive for inclusivity and believe in a united Australia, which starts with a recognition of First Nations' continued connection to lands, waters and communities," Chamber chair June Moorhouse said in a statement.
"On 26 May 2017 at the National First Nations Constitutional Convention at Uluru, the delegates drafted and endorsed the Uluru Statement from the Heart.
"The statement calls for a constitutional First Nations Voice to Parliament, and a Makarrata commission to oversee a process of treaty-making and truth-telling."
Ms Moorhouse said the chamber was grateful and humbled to acknowledge and respect the traditions and cultures of First Nations people.
She said the arts organisation, which is a peak policy and advocacy body representing the arts and cultural sector in WA, also expressed their support for the Uluru Statement from the Heart in full.
"The referendum vote is a personal choice for Individual Australians," she said.
"Our close partners, Reconciliation WA, offer information and yarning events and, together, we encourage everyone to be informed and use your vote.
"On 27 May 1967 Australians voted to recognise the rights of Aboriginal and Torres Strait Islander people in the census. Fifty-six years later we have another opportunity to transform who we are as a Country."
Debate on the Voice bill will resume in federal parliament on Tuesday, with a final vote in the lower house expected in the coming days.
It's expected that more than 100 lower house MPs will to speak to the bill before it is eventually passed.
The referendum is slated to be held in October or November this year.
