Dave Sweeney (pictured) stood on Melbourne's Collins St and told the crowd of about 30 why nuclear power stations are a bad idea and a step backwards for Australia.

Dave, a nuclear-free campaigner with the Australian Conservation Foundation, was also the co-founder of the International Campaign to Abolish Nuclear Weapons (ICAN), two things about which he is passionate and subsequently deeply committed.

He loves his work and, he believes, it helps pay his "planetary rent"

The December 3, Collins St, Melbourne nuclear power station protest during which Dave spoke was organized by the city's office of "Friends of The Earth".

Listen to this episode and Dave talks about why he helped set up the Nobel Peace Prize-winning ICAN and what international success means, personally and for the group
