Greg Chamberlain

Greg brings a lifetime of leadership, discipline, and operational experience to the Kokoda Track. He served for more than 35 years as an Infantryman in the Australian Regular Army, including active operational service in South Vietnam and Somalia, and concluded his distinguished military career as a Warrant Officer Class One.

Since transitioning from full-time service in 2004, Greg has remained deeply committed to health, fitness, and leadership, working within the fitness industry as a Personal Trainer and Group Exercise Instructor. A lifelong participant in sport — including Rugby League, Rugby Union, Boxing, and Touch Football — he maintains the physical readiness and resilience essential for leading in remote environments.

Greg has been guiding on the Kokoda Track since 2007 and has led more than 32 expeditions. His military background, combined with extensive personal research, allows him to provide trekkers with a clear and informed understanding of the Kokoda Campaign — not only the strategy and events, but the extraordinary hardship endured by the soldiers who fought there.

Respected for his steady presence and practical leadership, Greg supports trekkers with measured guidance, strong situational awareness, and a deep respect for the significance of the journey they are undertaking.

Based in Palmwoods on Queensland’s Sunshine Coast hinterland, Greg enjoys life with his wife Cheryl and their extended family. He remains passionate about maintaining an active lifestyle and considers it a privilege to continue guiding others across one of Australia’s most important historical landscapes.
