Aboriginal Australians who were near British nuclear tests in the 1950s and 1960s will receive improved health care.

Britain tested atomic weapons at various sites across SA and WA and instructed Indigenous people to move away before the tests.

Those who remained were subjected to extreme levels of radiation later linked to significant injuries and disabilities.

After decades of campaigning, Veterans' Affairs Minister Dan Tehan says those people will now receive improved health care from the Commonwealth.

“Subject to the passage of legislation, the measure will provide Gold Cards to Indigenous people present at or near Maralinga, Emu Fields or the Monte Bello Islands at the time of the British nuclear tests in the 1950s or 1960s,” Mr Tehan said.

Those affected will receive the veteran’s Gold Card, which covers most health costs.

The improved health care will be provided as part of a $133-million federal budget package for survivors of the British tests and veterans who served in Japan after World War II.
