Med-XPD Jungle/Tropical Medicine


This track near Rabaul, PNG is a reminder of the little-known yet significant experiences of an Australian military unit in WW2 known as the Lark Force. The Lark Force totaling 1200 men, the majority of whom were from 2/22nd Battalion, were sent to defend Rabaul against a Japanese invasion.

Lark Force not only was routed from Rabaul by a superior Japanese force on 23rd January 1942, but it was informed by  Australian authorities that there was to be no reinforcement,  no further support and no evacuation. Literally and realistically it became “Every man for himself” for Lark Force personnel retreating from Rabaul.

Totally unfamiliar with the local environment and in the context of thorough mayhem, these Australians fled from the invaders along the contemporary Lark Force Track. Faced with diseases, starvation, disorientation and climatic rigors approximately 250 returned to Australia. More than 160 personnel were massacred by Japanese at Tol, after responding to Japanese re-assurances of support. Another 850 personnel who were captured by Japanese were embarked on the “Montevideo Maru” which was sunk with total loss of life.

Today’s Lark Force Track is over 60km, traversing an extremely pristine jungle environment incorporating a few small villages. The current beauty and ruggedness of this track belies the horrors, struggles and bravery of those who fled on this track  in WW2. Nevertheless there are significant challenges and experiences for today’s trekker on this Track.

The Lark Force Track presents an adventure into unsurpassed environmental beauty, diverse cultural experiences, history and personal challenge beach.

This environment is perfect to learn hands on jungle and wilderness expedition medicine skills as we make our way through this unforgiving yet beautiful terrain.
