GREG CHAMBERLAIN ~ Kokoda Whisperer

Greg jumped on board with us back in 2015 and has successfully led over 30 Kokoda treks for our sister company Kokoda Spirit. Thanks to his military background and extensive research, he’s able to tell you the finer details of the history of Kokoda and the men who fought for our freedom. Greg gives our trekkers the military history side of the Kokoda Campaign history mixed with humour and the forming of a very special individual and group lifelong bond.

Greg served as an Infantryman in the Australian Regular Army for over 35 years including operational service in South Vietnam and Somalia.

Greg is very proud that his wife Cheryl, daughter Lyndal and son Marty have all separately trekked the Kokoda Track with him and is excited that his son Marty will now also be joining KokodaXtreme as a trek leader.

As you can tell, Greg is very passionate about keeping fit and healthy and will continue to return to Kokoda with our Xtreme adventurers for many years to come.



The love for Kokoda and fitness certainly runs in the Chamberlain family! Marty’s first Kokoda trek was an amazing, unforgettable experience made even better by sharing the journey with his father and fellow Kokoda Guide, Greg Chamberlain.

He’s has been involved in the fitness industry since 2006 and co-owns and operate Jetts gym at Mango Hill, Brisbane, with his sister and is currently a fitness trainer for a local under 17 rugby league team and a proud North Queensland Cowboys supporter.
