Big idea

Bushfires are a contemporary hazard controlled by fuel, weather and topography. Understanding fire behaviour — and First Nations fire knowledge — underpins management (14.2–14.3).

Cultural-content protocol (read first)

This chapter includes First Nations cultural burning. Handle it as living Indigenous knowledge:

Syllabus mapping (NESA Geography 11–12, 2022)

Activities — model answers

Activity 1 · Define

Model
Bushfire: a fire burning out of control in bush/scrub/grassland. Natural hazard: an extreme natural event that can harm people & environments. Natural disaster: a hazard that causes major damage or loss of life. Fuel load: the accumulated dry vegetation (leaf litter, bark, branches) available to burn.

Activity 2 · Big three

Model
Fuel load: more dry fuel = more intense, faster fire. Weather: high temperature + low humidity + strong wind dry fuel and drive the flames. Topography: fire spreads faster uphill (slope preheats the fuel ahead).

Activity 3 · Fire movement

Model
Ember attack: wind carries burning embers ahead of the front, starting new spot fires — so fire crosses roads/rivers. Surface fire burns undergrowth/litter; crown fire leaps treetop-to-treetop (far more destructive). Radiant heat is intense heat radiating from flames — it can kill before flames arrive, hence defensible space.

Activity 4 · Slope & climate

Model
Uphill: the slope preheats and dries fuel ahead of the flames, so fire accelerates (roughly doubling per ~10°). El Niño: hotter/drier eastern Australia → higher fire risk. La Niña: wetter → more plant growth that becomes fuel in later dry years.

Activity 5 · Fire & landscape

Model
Eucalypt adaptation: resprouts from epicormic buds under the bark after fire (or fire-triggered seed release). Cultural burning: deliberate, cool, low-intensity, patchwork burning by First Nations peoples to care for Country — reduces fuel loads and catastrophic-fire risk, protects fire-sensitive species, and encourages new growth.

Activity 6 · Short response

Model
Natural factors: lightning ignition; fuel load; hot/dry/windy weather; slope; drought cycles. Human factors: accidental/deliberate ignition; land-use and fuel management; climate change lengthening seasons. A strong answer separates ignition from spread and uses correct terms.

Differentiation & assessment

Support

  • Pre-labelled fire-triangle to annotate.
  • Word bank for the big three.

EAL/D

  • Pre-teach: fuel load, ember, crown fire, radiant heat, epicormic.

Extension

  • Use a topographic map to identify high-risk slopes/aspects.
  • Research how cultural burning is being revived in NSW fire management.

Assessment / homework

  • Activity 5 (endorsed-source inquiry) + Activity 6 short response.
