The organisers at the Aboriginal Tent Embassy on the lawn in front of Old Parliament House are planning a day of cultural events and speeches to mark the 50th anniversary of the embassy's establishment.
The day is to start at 9.30am when participants assemble at Garema Place in Civic to march, via Commonwealth Avenue Bridge, to the embassy.
"It's a culturally safe, family-friendly day and everyone is welcome," one of the organisers, Paul Girrawah House, said.
