Drones, bushfire risk and what it means for outdoor structures

The idea of fire services using drones to watch over fire-prone ground has moved quickly from novelty to everyday tool in many parts of the world, including Australia. Small aircraft fitted with ordinary and thermal cameras can map a fire edge, spot hot spots hidden by smoke and give crews a view that would otherwise need a helicopter. For anyone who lives with a deck, pergola or verandah on the edge of bushland, the technology is a reminder that fire behaviour around homes is studied in close detail, and that the way we build outdoors matters.

What aerial imagery tends to show

Post-fire images of suburbs near bush often reveal a pattern: houses are frequently lost not to a wall of flame but to embers landing on and around attached structures. Timber decks with gaps full of leaf litter, doormats, stacked firewood under a verandah and dry plants against posts can all catch alight and carry fire to the main building. Seen from above, the difference between a cleared, tidy yard and a cluttered one is often striking.

Practical points for Australian outdoor living

  • Know your bushfire attack level. In bushfire-prone areas, new decks, carports and pergolas may need to meet the construction requirements of the relevant Australian Standard for your site's rating. Your local council can explain what applies.
  • Choose materials with care. Non-combustible framing, metal roofing and suitable decking products can reduce risk where ratings are higher.
  • Keep it clear. Regularly sweep leaves from under decks and out of gutters on verandah roofs, and avoid storing flammable items beneath outdoor structures.
  • Have a plan. Your state fire service publishes free bushfire survival planning guidance worth reading before each season.
