Queenslanders are invited to witness history on Monday, 16 September, at the Ceremonial Hearing of the Truth-telling and Healing Inquiry in Meanjin (Brisbane).

The inquiry will hold its first public hearings from 18 to 20 September.

The event marks the beginning of a three-year process aimed at understanding the effects of colonisation on Indigenous people.

Waanyi and Kalkadoon man and Inquiry Chairperson Joshua Creamer anticipates that thousands will attend in person or via livestream.

"The Truth-telling and Healing Inquiry is a Queensland-first and I invite everyone to be open to learning more about our state's history and to approach the Inquiry with respect and curiosity," Mr Creamer said.

"The Inquiry will help us listen, share and collect evidence on a scale like never before, gaining a more accurate picture of how colonisation has impacted Aboriginal peoples, Torres Strait Islander peoples, and their families and communities.

"Upcoming Inquiry hearings will play a vital role in this three-year process, as we explore deeper, more personal first-hand accounts from our many and varied Aboriginal and Torres Strait Islander communities, including some hard truths."

The latest Census (ABS) shows the Brisbane local government area has Queensland's largest Aboriginal and Torres Strait Islander population, with 22,940 people identifying as such.

More than one third of the state's Indigenous population, around 82,000 people, reside in the Brisbane, Moreton Bay, Logan, Gold Coast, and Ipswich LGAs.

"All Queenslanders deserve the chance to be heard, understood and supported, and we've all got a responsibility to listen," Mr Creamer said.

"In Meanjin we will start Queensland's truth-telling process, which will include many first-hand and valuable accounts by Elders, before visiting communities across the state over the next three years.

"Through the Inquiry, we hope Queenslanders can better understand the valuable contributions and the unique needs and challenges of Aboriginal peoples and Torres Strait Islander peoples, and the power of acknowledging and embracing these."

The Truth-telling and Healing Inquiry kicks off with a Ceremonial Hearing on Monday, 16 September at the Brisbane Convention and Exhibition Centre.

Arrive by 9:30am for a Smoking Ceremony at 9:45am, followed by formal proceedings from 10am to 12pm.

Registration is recommended for in-person or livestream attendance.

Public hearings run from 18 to 20 September, 9:30am to 5pm daily, also at the Convention Centre.

No registration is needed for the public hearings.
