Evaluating a bushfire risk communication strategy
A rural shire of 9,000 people has one road in and out of its main settlement. A bushfire risk assessment rates 60% of the shire as 'high' or 'extreme' risk. The council proposes a communication strategy: a website with a real-time fire danger rating, SMS alerts to registered residents, and a community meeting each spring. Data show: 71% of residents are over 55; mobile coverage is patchy in the outer 30% of the shire; only 34% of residents registered for SMS alerts; and in a survey, 48% said they would 'wait and see' before leaving in a fire. The council claims the strategy will 'ensure all residents are prepared'.
1. Evaluate the council's claim that the strategy will 'ensure all residents are prepared', using the demographic and coverage data.
Read the worked answer
The claim is not supported. 'Ensure all residents' is an absolute that the evidence contradicts on several grounds:
- Digital exclusion. 71% of residents are over 55, a group with lower average digital engagement. A website-based rating assumes internet access and literacy; it will not reach everyone.
- Mobile coverage gaps. Patchy coverage in 30% of the shire means SMS alerts cannot reach residents there regardless of registration - a structural failure, not a behavioural one.
- Low registration. Only 34% registered for SMS means two-thirds are outside the alert system entirely. Even if all registered, coverage gaps would still exclude some.
- Behavioural resistance. 48% saying they would 'wait and see' indicates the strategy is not shifting the decision that matters most - when to leave. Information alone does not change behaviour; the 'wait and see' pattern is a well-known cause of late evacuation and deaths.
- Single road. With one access road, late evacuation risks congestion and entrapment, so timing is critical and a 'wait and see' norm is especially dangerous.
Verdict: the strategy may raise awareness among a subset, but it cannot 'ensure all residents are prepared'. The claim overstates reach, ignores structural barriers and does not address behavioural readiness.
2. Recommend improvements to the strategy and justify how you would evaluate their success.

Recommended improvements:
- Multi-channel communication. Retain SMS but add landline/robocall, local radio, letterbox drops, community noticeboards and in-person visits for the outer 30% with poor coverage. This addresses digital and coverage exclusion.
- Target older residents deliberately. Partner with aged-care providers, community groups and neighbours to ensure over-55s receive and understand warnings; use large-print materials and face-to-face briefings.
- Shift from information to decision support. Replace 'know the rating' messaging with concrete personal triggers (e.g. 'leave the day before a Severe or worse rating') and household planning. Address the 'wait and see' norm directly by publicising the single-road congestion risk and local stories.
- Registration drive. Set a target (e.g. 80% registration) and use community meetings, rates notices and local media to drive sign-ups.
Evaluation of success:
- Reach indicators: SMS registration rate; proportion of households receiving at least one channel; coverage gap closure.
- Knowledge/behaviour indicators: repeat the survey to track the 'wait and see' proportion (target: reduce from 48% to below 20%); measure household plan completion.
- Outcome proxy: evacuation compliance in the next real event or exercise; time taken to clear the single road.
- Equity check: compare indicators for over-55s and outer-area residents against the shire average to confirm no group is left behind.
Success should be judged against pre-set targets and disaggregated by group, not by the number of channels deployed.
