Hundreds of climate activists are set to blockade a resources conference in Perth, with police planning a major security operation in response.
Environmental groups including Extinction Rebellion, are planning a significant presence at Perth Convention Centre today where attendees will include the chief executives of BHP, Woodside Energy and Chevron Australia.
While activists insist they're committed to a peaceful demonstration and want to avoid a repeat of the violent scenes at protests in Melbourne last month, police are planning to deploy the biggest security operation seen in Perth since 2011.
