More than 80 people gathered in Murray Bridge to show their support for a group of people walking from Victoria to Adelaide in support of constitutional recognition for Aborigines and Torres Strait Islander.
As the Recognise team walked across the Murray Bridge the crowd, including students from Murray Bridge High School, joined in.
Recognise Communications Director Misha Schubert said the Aboriginal and Torres Strait Islander story was one of the longest unbroken records of human civilation but it was missing from the Australian constitution.
"That story needs to be there alongside the British inheritance," she said.
"Then we can stop living alongside each other in this land and start living together to forge a future together."
Recognise spokesperson Charlee-Sue Frail said the Recognise team had been on the road for 34 days raising awareness in communities as they travelled about the need to change the constitution.
"One of the great things is to get young people to step up and take over from those who have come before," she said.
Ms Frail said politicians on both sides of the fence knew referendums did not have a high success rate so wanted to wait to call one on Aboriginal constitution recognition until they knew the Australian public would back it.
"The interesting thing is the biggest yes vote in a referendum was the citizenship rights vote for Aborigines in 1967," she said.
"It got over 90 percent agreement."We are hoping to mirror that when we have our turn."
