Traditional owners from across South Australia have been urged to stand together to resist plans for two nuclear waste dumps in the state's north.
Groups opposed to the dumps, one being considered by the SA government to store high-level waste from other countries and one proposed by the commonwealth to store domestic low-level waste, will take to the steps of parliament house in Adelaide on Saturday.
Karina Lester, from the No Dump Alliance, says traditional owners need to send a strong message of opposition to the state and federal governments.
"All traditional owner groups need to unite and fight this as we all know the international waste storage facility is not going to be Norwood or Unley (in Adelaide), it will be in the far north of the state," she said.
Aboriginal Congress SA chairman Tauto Sansbury says people need to understand what building nuclear waste dumps means for future generations.
"We are talking about the importance of country and the preservation of culture and safety of our peoples," he said.
Conservation SA chief executive Craig Wilkins said Saturday's rally was another opportunity for all South Australian to express their concerns over the dump proposals.
The rally also marks the 63rd anniversary of the first British atomic bomb test at Emu Field, in SA's far northwest, in 1953.
