On November 29, 2025, a significant climate protest occurred off the coast of Australia, leading to the cancellation of a coal ship's arrival at the Port of Newcastle. Activists from the group Rising Tide utilized kayaks, small boats, and swimmers to block the shipping channel, prompting police intervention. As a result, 11 individuals were arrested and charged with alleged marine-related offences. The coal ship, named Cemtex Leader, was forced to turn back, although officials stated that other shipping operations at the port continued as planned. This incident reflects the ongoing debate in Australia regarding coal exports, which are a major part of the country's economy, and the rising urgency of climate change activism.
