Our Team

The owners are Geoff and Hwee Carter.

Between them, they have travelled to all of the continents in the world except Antarctica seeking hills to climb and hikes to experience.

They were lucky enough to have corporate careers that gave them the opportunity to travel. Upon reaching "that age" they looked for ways of travelling more and working less whilst maintaining a fitness level that helped travel. So they purchased West Oz Active Adventure Tours. They are fitter but are not sure on the working less bit!

Hwee Carter


You will most likely be dealing with Hwee when you call, email or text us. On occasions, she is allowed out of the office to assist in guiding larger groups. Hwee worked as a health and medical physicist for over 17 years and was introduced to the great outdoors when she met Geoff. Together with Geoff, they have been on many travelling, hiking and climbing adventures.

Geoff Carter

Head Guide

Geoff has climbed all over the world and is the head guide. Geoff has worked as a scientist in both academia and corporate positions. He has a passion for science, the outdoors and of course anything that involves ropes. Geoff has over 25 years of running and/or participating in outdoor adventure programs across 5 continents.

Josh Huitson

Coming from a background of emergency services and military roping, Sim has a keen eye for safety and is well practiced in helping people overcome their fears.

When he isn't in Karijini, he can regularly be found SCUBA diving or jumping out of perfectly good planes.

Growing up in Victoria with the Grampians at his front door step, Pat has always had a love for the outdoors and adventure.
