About 8000 people demonstrated for urgent action on climate change in Sydney's Belmore Park on April 2 in a powerful counter-mobilisation to a 2000-strong climate deniers rally led by right-wing radio shock jocks Alan Jones and Chris Smith from Radio 2GB held in Hyde Park.
The climate deniers rally was a repeat of a similar-sized rally held in Canberra a week earlier and is part of an attempt to build a right-wing populist Tea Party-style movement as exists in the US.
The climate change activists rally was organised by the internet-based group GetUp!
