As part of a Global Week of Action, Greenpeace Local Groups roll out activities to highlight the threats of overfishing the world's oceans. The 'Monsterboats' campaign calls for an end to trans-national industrial fishing of the worlds oceans and the promotion of instead sustainable, regional fishing practices that support local economies and fisheries. The Sydney local group in shark costumes are shown with a 6 metre Monster boat prop at Cronulla beach.
