The Coral Adventurer ran aground off Papua New Guinea due to navigation errors and high speed, but no one was injured.

The Australian-registered cruise ship Coral Adventurer ran aground off Papua New Guinea on December 27, 2025, 100 kilometers east of Lae, after navigation and speed errors during a course change. A chief mate attempted to reroute the vessel using digital systems, but autopilot delays due to a safety check caused the ship to miss a turning point and slow down. The crew increased speed to 8 knots—2.5 knots above intended—before manually overriding autopilot to correct course, leading to a reef strike. No injuries were reported. The Australian Transport Safety Bureau cited high speed and navigation missteps as key factors, with the investigation ongoing.
