Orion has announced it will send the National Geographic Orion on a second Melanesian voyage next year.
The decision comes after experiencing successful sales for the early 2014 itinerary.
The ship will sail on a 13-night voyage to Papua New Guinea, the Solomon Islands and Vanuatu enroute to Fiji.
Cruisers on the expedition will be able to buy pottery or wooden and stone carvings in Louisiade Archipelago; swim, snorkel and kayak around the islands; and see remnants from WWII.
The tour departs from Cairns on 5 November 2014 and concludes in Lautoka, Fiji.
Fares start from AU$12,550 per person twin share for a B stateroom.
