Travis Lovett has arrived at Parliament House with a plea from his Aboriginal elders.
"I have walked my part of the road. Now I ask this country to walk the next part with us," he told a crowd of hundreds of people.
The Kerrupmara Gunditjmara man had just presented a kangaroo skin to Prime Minister Anthony Albanese, inscribed with a letter calling for national truth-telling.
"The time has come for us to look honestly at ourselves," the first line reads.
Mr Lovett brought the message on a slow, 38-day walk, covering more than 500km of winding rivers from Melbourne to the nation's capital.
The final part of the journey was completed alongside hundreds of people from Canberra's Reconciliation Place to Parliament House, where he was met by the prime minister on Wednesday.
