Indigenous rights activist and anti-nuclear campaigner Yami Lester will be farewelled in a state funeral on Tuesday in traditional APY Lands in South Australia's far north west.
Mr Lester was best known for his work fighting for the clean up of Maralinga, the site of British nuclear testing in the 1950s, which eventually helped establish a royal commission in 1985 and subsequent compensation for those impacted.
The activist - who died late last month at the age of 75 - was left blind as a young man by the atomic testing which he called the "black mist".
He was awarded a Order of Australia medal for his services to Indigenous affairs and worked on land rights issues across South Australia and the Northern Territory.
His daughter Karina Lester said people were travelling from across the country for the funeral, with the South Australian premier and opposition leader both expected to attend.
"Today really is a sad day but a day to celebrate this wonderful man," Karina Lester told ABC radio on Tuesday.
Mr Lester's funeral will take place at the Walatina station on the APY Lands.
