Manage Social Media for Community Campaign

Two Casey residents running a community campaign opposing Casey Council's decision to build a $310K carpark inside Wilson Botanic Park, Berwick. Council overrode its own officers and majority community feedback to approve this. We need someone to run social media for 3 months to build public pressure.
