What a deck costs in Darwin
Darwin's cyclone exposure governs an elevated deck: it must be tied down and braced to handle extreme winds, which affects the substructure and cost well beyond a mild-climate deck, and termites are the second factor, as any timber deck in the tropics is at high risk, so termite-resistant hardwoods, treated timber or composite on a steel frame are the sensible choices.
Tropical sun, humidity and salt weather a timber deck fast and corrode its fixings, so composite on corrosion-resistant fixings is very popular for the low maintenance it offers, and pool decks are common. Remoteness adds freight, and the small trade market keeps labour high. For a Darwin deck, the cyclone tie-down, the termite-resistant and salt-durable materials, and the remote market are what shape the quote.
