Australia doesn't need to be convinced that exterior sprinklers work against bushfire. Australia produced the science. CSIRO researchers and AFAC — the national council of fire authorities — jointly developed the country's guideline for spray systems designed to defeat ember attack. What Australia hasn't done yet is deploy that science at the scale its communities need. That's the gap Prodigy exists to close.

The Number Every Australian Fire Authority Agrees On

The NSW Rural Fire Service puts it bluntly: over 80% of homes destroyed during bushfire emergencies are lost to ember attack — often hours after the fire front has passed, when nobody is there to defend them. CSIRO post-fire surveys going back to the 1983 Ash Wednesday fires reach the same conclusion. Homes don't usually burn because a wall of flame reaches them. They burn because millions of burning fragments rain onto dry roofs, gutters, decks and gardens.

The Guideline Most Australians Have Never Heard Of

After decades of post-fire evidence, AFAC and CSIRO published a national guideline with an unglamorous name and an extraordinary implication: "Bushfire spray systems for the protection from ember attack." It codifies what survivor after survivor had reported — properties that stayed wet through the ember storm stayed standing.

The Victorian Royal Commission into Black Saturday heard the same pattern: among the homes that survived in the worst-hit areas, active water application — sprinklers, pumps, sprayed rooflines — appeared again and again. The physics has never been in dispute. A saturated surface cannot ignite, and air loaded with moisture starves an ember of the dry fuel it needs.

The Humidity Bubble: What an Engineered Spray System Creates

💧

Saturated Surfaces

Roof, walls, decks and gardens too wet to ignite

🌫️

Elevated Humidity

Moisture-loaded air around the home extinguishes embers in flight

❄️

Evaporative Cooling

Surface temps held below ignition point

Together these form a protective moisture envelope — a humidity bubble — over the property for the entire ember-attack window.

From One Home to a Protected Street

Here's what the Australian evidence points to next: the humidity bubble scales. When neighbouring properties run engineered spray systems simultaneously, their moisture envelopes overlap. A street becomes a corridor of elevated humidity that embers cannot cross alive. This is precisely how fire agencies protect townships during campaigns — sprinkler lines around the perimeter — except a permanent, resident-owned network doesn't depend on a strike team arriving in time.

Prodigy Wildfire Solutions installs engineered bushfire sprinkler systems across NSW, Victoria and Queensland — automated ember detection, roof-mounted coverage designed to the property, and remote app activation so the system defends your home after you've evacuated. It's the AFAC/CSIRO concept, engineered and maintained as permanent infrastructure.

Working Together: Communities, Councils, Brigades

Australia's bushfire story has always been a community story — brigades staffed by volunteers, street-level fire plans, neighbours defending neighbours. Community-scale sprinkler protection is the natural next chapter. Rural Fire Service brigades, community associations and local councils partnering on street-by-street protection can change the survivability of entire towns — the same way community FireSmart programs did in Canada and FEMA-funded sprinkler networks did in the United States.

The Science Is Australian. So Is the Solution.

Protect your home — or your whole street.
