The activism group has recruited the likes of Peter Garrett for the demonstration, which has been promoted as a "protestival" designed to block access to the Port of Newcastle.

The NSW Supreme Court has accepted a challenge from the state’s police commissioner to a climate protest planned in Newcastle later this month.

The protest, organised by Rising Tide, would see activists attempt to block access to the Port of Newcastle.

Rising Tide says the multi-day demonstration will go ahead regardless of the court’s decision.
