Exclusive: The street artist’s latest work saw 60 people parade through Lake Cawndilla in NSW, holding aloft enormous portraits of local farmers and leaders as they fight to save Australia’s vital river system

The mood around Lake Cawndilla in western New South Wales on Saturday is funereal but defiant, as a procession of around 60 locals parade through scrub and sand around its banks.

They carry between them a series of 30m-long cloth figures: three local citrus farmers and prominent Baakandji artist William Badger Bates.
