A rural firefighter is among a group of climate change activists arrested over a protest on the Sydney Harbour Bridge that disrupted peak hour traffic.
NSW Police urged drivers to avoid the area on Wednesday morning after the group parked a truck on the Cahill Expressway about 8.30am, blocking near the south pylon, over Circular Quay and The Rocks.
Two of the group climbed onto the truck's cabin, holding a Fireproof Australia flag and lighting a flare, while another two glued themselves to the bridge.
