A climate change protest planned for the Sydney Harbour Bridge has been derailed after activists hit a roadblock in their effort to disrupt traffic.
Activists from Fireproof Australia vowed to light flares and walk across the bridge on Thursday as part of a "political prisoner protest" over the jailing of their colleague Andrew George, who is spending his birthday behind bars.
However, delays and a map with a poorly placed drop pin meant protesters scattered around the bridge and no protest took place.
