Table 1. Fuel Assessment Fuel Areas 1 and 2.

The Department of Natural Resources, Mines and Energy maps the vegetation present as a combination of
(70%) RE12.2.1 and (30%) RE12.2.5 with default total available fuel loads of 4.5t/ha and 24.1t/ha respectively.
Site assessment supports their vegetation classification, and working on 70% of 4,5t/ha plus 30% of 24.1t/ha, a
value of 10.38t/ha is suggested. This aligns with the fuel load assessed above. For the purposes of site specific
fire modelling in accordance with Method 2 under AS3959-2009) a total available fuel value of 11t/ha (6t/ha of
which is surface and near surface fuel) is applied to site specific fire modelling in Section 6.
