A 'dangerous' tropical storm building off the coast of Queensland has forced a cruise ship headed into the Pacific to turn back.
The Carnival cruise ship Luminosa, which was bound for New Caledonia, changed course on Wednesday morning and is now set to return to Brisbane.
The ship's captain, Carmelo Marino, told passengers in a letter that he had no choice but to abandon the planned itinerary.

'Regrettably, given the forecasted path of the storm, we will not be able to deliver our planned South Pacific itinerary,' Mr Marino said.
The storm system, which was sitting 800km offshore from Cairns in the Coal Sea, is expected to develop into a category two cyclone by Friday.
It is expected to bring destructive winds and could cause minor building damage.
A category two storm gusts of up to 164 kilometres per hour and sustained winds of up to 117 kilometres per hour.
The weather office said the cyclone is likely to be called Gabrielle.
Initial concerns are held for the 2200 residents on Norfolk Island, where the storm will hit on Saturday.
