Passengers rescued from a Russian research ship that became trapped in thick pack ice in Antarctica last month have finally arrived in Australia.
The 52 scientists and tourists had to be airlifted from the Akademik Shokalskiy onto an Australian ship after several failed rescue attempts.
Expedition leader Chris Turney explained how they managed to keep morale up for so long.
