part, ostensibly to express their appreciation and concerns for the environment. 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. For the most part, sections of the Walk were co-ordinated 'tag-team' style, with new coordination teams assembled for sections of the Walk. During the 26 days from March to April 1988, the Great Walk formed an entirely self-supporting, mobile community of 200 to 500 people that supported itself on contributions from participating walkers per day. Bambooroo Bambooroo was a magazine published by Great Walk Networking from May 1988 to May 1990. Its focus was on environmental issues of concern primarily to the South West region of Western Australia. Bambooroo means "message stick" or "message bearer" in the Nyoongah language. During the first Great Walk, a bambooroo was presented to the Walkers at a corroborree held in Kirup, Western Australia. Ken Colbung described the bambooroo to the Walkers and supporters who collected at Parliament House on 20 April 1988 as a "spiritual message stick" that "protected (the Walkers) from the weather." He later said a message stick "has a very special spiritual significance for the messenger, and when we dedicated it at Kirup it then took all the hopes and realisations of the people present that they would have a walk that would not be caught up in the elements, so that rain would not flood them out or that mud would not be there, that the winds would not be too strong, but the elements would be very controlled and it'd allow the Walkers a peaceful walk up to Perth."
