Bushfire-resisting timbers

Seven commercial timbers used in construction in Queensland are considered to be bushfire-resisting, where the cross-section thickness of the member is at least 18 mm thick:

Standard trade name Botanical name
ash, silvertop Eucalyptus sieberi
blackbutt Eucalyptus pilularis
gum, red, river Eucalyptus camaldulensis
gum, spotted Corymbia maculata, C. henryi, C. citriodora
ironbark, red Eucalyptus sideroxylon
kwila (merbau) Intsia bijuga, I. palembanica
turpentine Syncarpia glomulifera

These timbers have been tested and assessed against the criteria specified in AS 3959-2009-Construction of buildings in bushfire-prone regions, incorporating the amendments for fire-retardant-treated timbers.
