Aircalin, previously known as Air Calédonie International, a local carrier 55 percent owned by the territorial government, links New Caledonia to Auckland, Brisbane, Nadi, Osaka, Papeete, Port Vila, Seoul, Sydney, Tokyo, and Wallis Island. In Tokyo, Aircalin connects with Air France flights to Paris.
The most direct access to New Caledonia from North America is on Aircalin's twice weekly flight to/from Nadi, Fiji, although connections through Tahiti or Australia are more frequent. It's often difficult to get a booking on flights between Fiji and Nouméa because the planes arrive full from Wallis Island.
The national airlines of several neighboring countries also fly straight to Nouméa: Air Austral from Réunion; Air New Zealand from Auckland; Air Vanuatu from Port Vila; and Qantas from Brisbane and Sydney. All of the above flights operate out of La Tontouta Airport (NOU).
Joining a yacht as crew in Nouméa is possible. From September to November plenty of boats will be leaving for Australia or New Zealand, and you can also hitch rides to Vanuatu and the Solomon Islands. Skippers sometimes post notices at the Nouméa Youth Hostel.
