During the KimberleyUltramarathon on 2 September, a bushfire raced through the course, engulfing a group of five participants at El Questro Station. Two men escaped the flames, suffering severe burns but the two females were trapped, each suffering critical injuries. Thirty grass fires were burning in Kimberley at the same time. Several other fires were burning through the Kimberley, resulting in the loss of 60,000 hectares (150,000 acres) of grassland. It has since been discovered that Kimberley locals were lighting fires before and on the day of the race
