What a timber decking costs in Brisbane
Brisbane's high termite pressure is the central concern for a timber deck: the boards and especially the frame must be a termite-resistant hardwood or properly treated timber, since a susceptible species in this climate is a genuine liability, and on the elevated Queenslander decks that define the city the clearance and detailing to keep timber dry and inspectable matter as much as the species. Naturally durable hardwoods like spotted gum and ironbark are the sensible choice here for both termites and the weathering.
The subtropical humidity, intense UV and storm-season rain weather a timber deck hard, greying and splitting it, so oiling and upkeep are a recurring commitment in Brisbane's climate, more so than in the drier capitals. Labour sits around the national baseline with a strong supply of deck builders, so a timber deck is affordable to build here. The trade-off against composite is clear in this climate: timber is cheaper upfront and warmer underfoot, but the termite risk and the UV-driven maintenance are the price of it.
