11 & 12 January No change from the above strategy, (10 January).
13 January Weather conditions seemed quite favourable and it was intended that the fire would be contained in the west by backburning along the Ettrema Trail. The machinery was still working on the trail construction.
During the afternoon there was a wind shift from the north east which accelerated the main fire up towards the trail. The crews that had been working on the trail upgrade decided to withdraw but in so doing were subjected to a fire overrun situation. Some of the NPWS staff involved in this situation had extensive fire experience and showed great initiative in making safe. At the height of the incident these personnel involved became concerned that they could not contact a helicopter that was directly above them, despite the fact that both the vehicles and the aircraft were being monitored from Fire Control. As a learning outcome for crews working with air support it is worth noting that, due to the wave propagation characteristics of the radios, problems should be anticipated when the aircraft is directly overhead. In this situation communications would have been more effective working through an 'Air Attack Supervisor' who would be monitoring the situation without being directly overhead.
As a result of the overrun situation the fire continued towards the west and initially it seemed that it may travel through to the Tolwong Road. Subsequently this proved to not be the case. |
