Orion Expedition Cruises is new, and debuted in April 2005 as Australia's first world-class expedition cruise line. Its newly built 106-guest ship, the Orion, can be best described as combining modern ship design with maritime and environmental technology. This is really expedition cruising for groups at its best, complete with onboard lecturers, yet a modern cruise experience that takes guests to the unspoiled destinations in and around Australia.
