Ports North Accelerates Cairns Dredging After Carnival Diversions
Carnival Splendor instead anchored off Yorkeys Knob, where passengers transferred ashore by smaller boats after the channel fell below its designed depth of nine metres.
Ports North has accelerated maintenance dredging in Trinity Inlet after heavy silt accumulation left parts of the Cairns cruise channel too shallow for large vessels. Work began September 18 following itinerary changes involving Carnival Encounter and Carnival Splendor.
Sections of the navigation route have fallen below the port’s designed depth of 9 metres, restricting access to the Cairns Cruise Liner Terminal. The disruption has already sent one Carnival ship about 350 kilometres south to Townsville and required another to operate a tender call from Yorkeys Knob.
Dredging targets unusually heavy silt buildup
Queensland maritime authorities issued a navigation notice covering dredging in Cairns Harbour and the Cairns Channel on September 18. Crews are scheduled to continue the campaign into early November.
Silt accumulated more quickly than usual in Trinity Inlet, leaving insufficient depth for some deep-draught cruise ships to make a safe transit.
Carnival informed passengers four days before Carnival Encounter’s September 5, 2026 departure from Brisbane that its planned Cairns visit could not proceed. “Current channel depths have reduced and are now too shallow to allow for the safe passage of our ship,” the line said in its guest notice.
The 108,865-gross-ton ship, which can accommodate approximately 2,600 passengers, retained its September 7 Willis Island call. Airlie Beach moved forward to September 8, replacing Cairns. Townsville was added for September 9.
Prepaid Carnival shore excursions in Cairns were automatically refunded, while Townsville excursions became available after embarkation through the Carnival HUB app and Carnival Adventures Desk. The revised schedule also pushed the ship’s September 11 return to Brisbane from 7 a.m. to 8 a.m. Carnival did not outline compensation for passengers whose onward arrangements were affected by the one-hour delay.
Cairns loses a call to Townsville
Townsville was able to receive Carnival Encounter after completing a A$251 million channel-widening project designed to accommodate vessels measuring up to approximately 300 metres. Cairns businesses lost the potential spending associated with the cancelled visit by the ship’s passengers and roughly 1,100 crew members. The affected channel leads to the Cairns Cruise Liner Terminal at Trinity Wharf, which is within walking distance of the city’s restaurants, shops and tour operators.
Carnival Encounter remains scheduled to depart Brisbane on September 26 for another Great Barrier Reef cruise, including an overnight Cairns call beginning September 29. Carnival had not announced a change to that visit when it notified passengers about the earlier cancellation.
