Tony Abbott's political future could be under threat from a group of activists who have been organising environmentally conscious voters to join Liberal party branches on Sydney's north shore - a move that could unseat the former prime minister.

Billing themselves as "the counterweight" to the pro-coal power Monash Forum, the North Shore Environmental Stewards have held at least two recruitment functions at which attendees were urged to tap into their networks of environmentally conscious people to join the Liberal party branches in Abbott's seat of Warringah and on the lower north shore.
