Our Background

Our Spirit was established by Aidan Grimes in 2004 to support the growing demand for adventure challenges and adventure treks from our corporate clients under our previous name of Wellbeing Solutions Pty Ltd, where we have been providing corporate health and wellbeing programs and adventure walks since 1989. Since then, Aidan has become an exceptional trek leader and keynote speaker.

Our Spirit's Adventure Treks are as much about celebrating and commemorating the achievements of historical legends as they are about motivating you to reach your highest potential today.  It's about "having a go" and gaining an appreciation of the things our indigenous people, war heroes, pioneers, and modern sports people endured and how that can be translated to you personally.

For example, our PNG adventures emphasize the indigenous, cultural and historical significance of the Kokoda Track, Black Cat Track and Shaggy Ridge Tours, including the 1942 battle that saved Australia from foreign invasion. 

Many people have the training, skills and knowledge to achieve great things in life; but it's your passion, instinct and spirit that gives you an edge.  We create an environment for you to experience something real and out of the ordinary - experiences that remove any perceived limitations you may have.

Our Culture

Our Spirit adventures are synonymous with key events that shaped Australia's evolution, such as the 1942 battle on the Kokoda Track that saved Australia from foreign invasion. Our adventure treks are as much about celebrating and commemorating what historical legends achieved in their time, as what we are capable of achieving in our lives today. Our Spirit creates the perfect environment for you to develop an appreciation of what our war heroes, indigenous people, pioneers and modern sports people endure(d) and how that can be translated to you personally.  We are dedicated to providing opportunities for you to experience what's out there through adventures that are rich in cultural, environmental or historical significance and that are often extreme in nature.  Our Spirit delivers adventures in a unique way that enables you to remove any perceived limitations you may have and reach your highest potential as an individual as well as understanding the collective power of a team.
