SA dump could allow foreign waste: Greens

The Greens say a proposed nuclear waste dump on South Australia's Eyre Peninsula could be a "Trojan Horse" for storing other countries' high-level waste.

The federal government has short-listed six sites - two near Kimba and another north of Port Augusta in SA's mid-north - for Australia's first permanent nuclear waste dump for low-level and intermediate domestic waste.

Greens upper house MP Mark Parnell will visit Kimba residents on Monday to canvass concerns about the dump, saying even intermediate-level nuclear waste could be dangerous for hundreds of thousands of years.
