The organisation of the first Walk was also an Australian Bicentenary celebration to appreciate the environment of Southwest Australia, which is home to a relatively small but unique tall forest heritage: the world's only Eucalyptus marginata (Jarrah), E. diversicolor (karri), E. jacksonii (Tingle), E. wandoo subsp.

[3] The Western Australian forests have been extensively challenged by significant threats: earlier destruction due to settlement patterns and later clearfelling for woodchipping, mining for mineral sands and bauxite, as well as forestry practices that showed little interest in long term sustainability.

The Great Walk was launched with an Aboriginal dance ceremony to "protect the walkers, and attune them to the country through which they would travel."

These expressions were felt to be conveyed by a document called the Great Walk Tree Charter, which was carried to Parliament House where it was presented to the Premier of Western Australia, Peter Dowding.

The Great Walk required a great deal of planning and coordination: the route had to mapped, checked and marked on the ground, support crews and equipment assembled, transport arranged, child-care, first aid and medical personnel coordinated and a mobile catering system put together, able to serve 200-500 people at a time.
