Deliberately lit vegetation fires have the greatest destructive potential of any intentionally lit blaze. The ’Black Saturday’ bushfires of 7 February 2009 in Victoria, Australia, killed 173 people, injured 414 and destroyed 3500 buildings, including two entire towns (Teagne et al, 2010). Even before the fires had abated police and fire-fighters revealed that several had been deliberately lit (Silvester, 2009). The subsequent Royal Commission attributed four of the large fires to arson. These four fires caused 52 deaths and burnt approximately 2000 km2 of land, an area slightly larger than that of Greater London (Teague et aI, 2010). The community was united in its outrage that anyone would intentionally set a bushfire, particularly on a day with the most severe fire danger rating in over 20 years. The question of why anyone would set such fires is, unfortunately, not easy to answer, as there has been little investigation of those who deliberately light bushfires, especially in Australia. The lack of research in this is somewhat surprising, given that events like Black Saturday are not uncommon in Australia and other fire-prone regions. The Australian Institute of Criminology estimates that 25 000-30 000 bushfires are deliberately lit in Australia each year (Bryant, 2008). Disaster-level bushfires (those resulting in more than $10 million in damage) cost the Australian economy an annual average of $77 million even before the associated costs of police and courts and the intangible human and social costs wrought by large fires are considered (Department of Infrastructure, Transport, Regional Development and Local Government, 2001). Estimates from the USA suggest that between 20% and 25% of wildfires are deliberately lit, with rates dependent on location (Federal Emergency Management Agency, 1994; Hall, 1998). Even in the UK, where vegetation fires rarely result in the type of widespread destruction seen elsewhere, it is thought that some 20% of fires in open countryside are the result of arson (Lewis, 1999).
