Ben Wallis operates an international charter service with the fully equipped 75′ steel-hulled motor sailor Australis – a purpose-built vessel for high latitude expedition sailing.

Australis is based in the Southern Hemisphere and is configured for both hard working commercial projects and laid-back luxury cruising.

She is fully equipped to support expeditions, film crews, scientists, photographers, mountaineers, skiers, snowboarders, artists, bird watchers, divers, sightseers and adventurers of all descriptions.

In addition to all the luxuries of a well-appointed cruising vessel, Australis has large storage areas for equipment and a workshop.  She carries 9 passengers plus the Ocean Expeditions crew and is registered as a commercial “Category 0 (zero – Unrestricted)” vessel.  Click here to read more about our services.


Ben operates year-round bouncing between the summer in the southern polar region during October to April and the summer in the northern polar region during July to September.

A pioneer in Antarctica expeditions

Australis was privileged enough to be the first Australian yacht to become a full member of the International Association of Antarctica Tour Operators (IAATO), where the key is to follow responsible environmental policies. All those visiting Antarctica will be advised of minimum impact practices & minimum approach distances to wildlife.



Australis has a satellite tracking device fitted so if you have family and/or friends onboard you can track their progress during the voyage anywhere in the world.
