World spotlight shines on Maralinga horror

Sue Coleman-Haseldine was a toddler crawling around in the dirt when the winds brought the black mist.

Her white nappies on the washing line were burnt.

It was in the 1950s when the British began testing nuclear weapons at Maralinga in the South Australian outback.

The legacy of the bombs dropped continues to haunt the 67-year-old Aboriginal grandmother.

"We weren't on ground zero at Maralinga, otherwise we would all be dead," she told AAP.

"I was born and grew up on a mission at Koonibba, but the winds came to us."

Ceduna, the main township before the Nullarbor, is the cancer capital of Australia, Ms Coleman-Haseldine says.

She's had her thyroid removed and will be on medication for the rest of her life.

Her 15-year-old granddaughter is also battling thyroid cancer.

There are birth defects and cancers right across the community.

"It's changed our genes," she said.

"These diseases weren't around before the bombs."

On December 10, Ms Coleman-Haseldine will be in Oslo for the Noble Peace Prize award ceremony.

The International Campaign to Abolish Nuclear Weapons (ICAN) is being recognised for its work to achieve a treaty-based ban on nuclear weapons.

So far 122 countries have adopted the treaty, excluding Australia and countries with nuclear weapons - the US, UK, Russia, China, France, India, Pakistan, North Korea and Israel.

Only three countries have ratified the treaty and 50 are needed for it to become international law.

ICAN is a grassroots movement that began in Carlton, Melbourne more than a decade ago.

In Norway, Ms Coleman-Haseldine will tell the story of her people and their contaminated land.

"You've got to keep the past alive to protect the future," she said.

Ms Coleman-Haseldine hopes Australia will reverse its opposition and sign the treaty.

The Turnbull government has ruled that out but the Labor Party will debate the issue at its national conference next year.
