Has anyone done any research as to the number of climbers in Tasmania? I am putting together a grant application for a book on the history of Tasmanian climbing. The Tas Community Fund application needs to know the number of people in the community who might benefit from such a publication. 

If we were to count climbers who go to the crags fairly regularly, indoor climbers who go to various gyms, outdoor ed and TAFE courses that do climbing, members of the CCT...can anyone make a reliable stab at approximate numbers?

Thanks,

Gerry
