A tour of cultural sites across the south-west aims to highlight the connection between indigenous people from North America and Australia.
Susan Stark Christianson, who lives in Alaska, said they had been invited to hold a “spirtual unity of tribes gathering” in Australia by Brambuk chairman Geoff Clark.
Ms Christianson said the gatherings, started by an Alaskan elder, had been held all over the world.
“We share indigenous ceremonies, we share stories, we share our culture with one another,” she said.
“This year we brought together grandmothers from various tribes around the world.”
Ms Christianson’s project - based on the indigenous teaching that “there won’t be peace on earth until the voices of the grandmothers are heard” - had taken her all over the world.
“So bringing the grandmothers together and bringing the grandmothers here is part of fulfilling that and have our voices be heard and talk about what’s really important,” she said.
“We’ve been able to participate in some ceremonies, connect with the people here and connect with the spiritual story lines that are part of our stories, our prophecies as well.
“The aboriginal people here in this part of the world and the land here are very important and connected to our stories in the north.”
