The Rising Tide “People's Blockade” of the world's largest coal port began on November 19.
More than 300 people have joined the action already in defiance of attempts by the state government to prevent it from going ahead. Thousands are expected throughout the week.
Aunty Theresa conducted a smoking ceremony to welcome participants.
Rising Tide organisers recounted the attempts by police, the state government and the Port Authority to prevent or restrict the People's Blockade at a briefing session to participants.
