Mark CampbellAlmost two years after a tornado tore through Bunbury on 10 May 2024, the Western Australian coastal city is still completing repairs — and many Australian homeowners still do not know what structural checks to carry out after severe storm damage.
The Bunbury tornado remains one of the most significant severe weather events to strike a suburban Australian area in recent memory. In under ten minutes, the storm damaged 212 properties across South Bunbury, Withers, Carey Park, and College Grove, destroying 19 homes entirely and forcing 41 residents to evacuate. More than 3,300 properties lost power. Three weeks later, a second severe storm hit East Bunbury and the Koombana Bay area, damaging a further 101 properties. As the second anniversary approaches and the community continues recovery, the event is prompting Australians in storm-prone regions to ask: is my home ready for the next one?
What the Bunbury Tornado Revealed About Australian Homes
The speed and destruction of the Bunbury tornado exposed a gap many homeowners had not anticipated: the difference between cosmetic storm damage and structural compromise. Roofs with missing tiles looked alarming but were often repairable. Buildings where wall fixings had shifted, ridge capping had lifted, or ceiling battens had fractured presented deeper safety risks that were less visible from street level.
According to the Australian Building Codes Board, homes built to older standards — particularly those constructed before the 2010 National Construction Code revisions — may lack the wind-bracing requirements now mandatory in cyclone and high-wind zones. In Bunbury's case, many affected properties were residential homes built in the 1970s and 1980s.
Emergency building assessors working in the aftermath of the tornado noted that property owners often underestimated the extent of their damage because internal structural issues are not visible without roof access or a professional inspection. Several residents who initially believed their homes were structurally sound discovered weeks later that roof-to-wall connections had loosened, presenting long-term risk.
Five Things to Check After a Severe Storm
For homeowners in storm-prone regions — whether in Western Australia's south-west, Queensland's cyclone belt, Victoria's stormy south-east, or New South Wales's coastal areas — professional inspection is the safest path after any significant storm event. But there are preliminary checks that can help you understand the urgency:
1. Ridge capping and roof tiles: From the ground with binoculars, look for lifted, cracked, or missing tiles along the ridge line. Even one missing tile can allow water ingress that damages ceiling battens, insulation, and electrical wiring.
2. Gutters and downpipes: Blocked or detached gutters redirect water against your wall cavities. After a storm, check whether gutters are still firmly attached and flowing freely.
3. Ceiling stains: New water marks on ceilings — particularly in corners — indicate water has entered the roof space. Do not assume this is minor; ceiling insulation that stays wet can cause mould and compromise electrical safety.
4. External wall cladding: Look for gaps, lifted panels, or cracked render. Wind-driven rain can penetrate gaps as small as 2–3mm into wall cavities, causing long-term moisture damage that becomes expensive to remediate.
5. Fencing and retaining walls: Damaged fencing is often dismissed as cosmetic, but fallen fencing panels can indicate that footings have shifted. Retaining walls that have moved require immediate structural assessment before further rain saturates the soil.
When to Call a Professional
The Bunbury experience showed clearly that cosmetic repair and structural repair are different categories of work. A tradesperson who patches roof tiles is performing maintenance. A qualified building inspector who assesses whether your home's structural integrity has been compromised is performing a different, more critical service.
Under Australian standards, a post-storm structural inspection should be performed by a licensed builder, structural engineer, or qualified building inspector — not merely a general handyman. In storm-damage insurance claims, a formal written inspection report significantly improves the chances of a full claim being approved.
If your home was damaged in a recent storm event, your insurer is required to advise you on what evidence they need to assess your claim. In most cases, an independent building report obtained before final repairs begin will protect your entitlements under the policy.
The South West Development Commission in Western Australia, which coordinated the 2024 Bunbury recovery, noted that some affected homeowners struggled to find qualified tradespeople during the immediate aftermath due to demand surge. Having a relationship with a trusted local builder before a storm event — and understanding your policy's obligations — reduces the pressure of making fast decisions during a crisis.
Preparing Your Home Before the Next Storm
Australia's storm season does not follow a neat calendar. While south-west WA is historically most at risk from November through April, severe thunderstorms with tornado-producing supercell activity have struck outside these windows, and climate data shows increasing unpredictability in severe weather events.
The Insurance Council of Australia recommends that homeowners in high-risk zones conduct an annual pre-storm inspection of their roof, guttering, and drainage systems. For homes older than 30 years, engaging a licensed builder to review structural fixings — particularly roof-to-wall connections — can identify vulnerabilities before they become emergency repairs.
Community resilience was widely praised in Bunbury's recovery. Mayor Jaysen Miguel acknowledged that local emergency services, the SES, and relief organisations performed admirably under extreme pressure. But resilience also means preparation: knowing your local hazard zone, maintaining your home to current standards, and having a qualified home improvement expert you can call when damage occurs.
