Brisbane City Council Cyclone Alfred: Response, Floods & Reviews

For more than five decades, Brisbane figured it was mostly safe from tropical cyclones — until March 2025 brought Severe Tropical Cyclone Alfred and the wettest 24 hours the city had seen since 1974.

An independent review released 20 May 2025 found Council delivered an effective, strong response despite the unprecedented nature of the event.

Which Brisbane suburbs will be affected by Cyclone Alfred?

The cyclone’s trajectory spared Brisbane a direct eyewall strike, but its rainbands proved devastating. The system crossed the coast north of Brisbane on 8 March 2025, delivering the heaviest rainfall the city had seen in more than five decades. Ex-Tropical Cyclone Alfred continued to produce intense rainfall for several days, with flash flooding warnings issued for suburbs such as Carindale, which recorded 144 mm in just six hours as the storm’s remnants passed through.

Flood-prone areas identified

Brisbane’s flood history shaped where impacts hit hardest. The city learned painful lessons from the catastrophic February 2022 floods, which followed an identical track to the devastating 2011 event. Suburbs with properties in known flood zones — many still recovering — faced renewed inundation when Alfred’s rainfall overwhelmed urban drainage systems. Guy Carpenter’s post-event analysis notes that heavy rainfall caused localised inundation in flood-prone areas across the region.

Council warnings and maps

Brisbane City Council maintained its FloodWise Property Report system throughout the event, allowing residents to check their property’s flood risk. The review highlighted that Council’s approach to public communication and evacuation coordination built on improvements implemented after the 2022 Flood Review. PreventionWeb reported that as remnants of ex-Tropical Cyclone Alfred moved through in mid-March, authorities urged residents in historically flood-affected areas to remain “very high alert.”

The pattern of repeatedly flooded suburbs — and the Council buyback scheme targeting 16 properties — confirms that certain areas carry structural risk that individual preparedness cannot fully mitigate.

Did Cyclone Alfred already hit Brisbane?

Yes. Cyclone Alfred made landfall as a tropical cyclone on 8 March 2025, and its impacts extended well beyond that date. The Australian Reinsurance Pool Corporation declared the cyclone period from 25 February 2025 8:30pm AEST until 6:00am AEST on 8 March 2025, though the Queensland Government defined the broader severe weather event period as 1–16 March 2025.

Crossing timeline

The system approached from the Coral Sea, with public transport suspended after the final service on 5 March 2025 as pre-storm preparations intensified. The cyclone crossed the coast north of Brisbane near Moreton Bay on the morning of 8 March 2025. However, the most severe flooding occurred after the system transitioned to an ex-tropical cyclone and stalled over South East Queensland, dumping extraordinary volumes of rain from 9–10 March 2025. This pattern — a relatively weak direct impact followed by catastrophic rainfall — proved costlier than a direct hit might have been.

Impact confirmation

Brisbane recorded 275.2 mm of rainfall on 10 March 2025, the wettest 24-hour period since records from January 1974, according to Guy Carpenter’s post-event analysis. Wind gusts exceeded 100 km/h across the Brisbane and Gold Coast areas. Beaches were stripped of sand, and coastal infrastructure was weakened by abnormally high tides. The 2025 Queensland floods, spanning late January to April 2025, caused at least 33 fatalities and more than $1.2 billion AUD in damages as of mid-April, per Wikipedia’s compilation of available data — though Brisbane’s portion of those costs remains disaggregated.

Should I tape my windows for Cyclone Alfred?

Emergency management authorities consistently advise against window taping as a cyclone protection measure. The practice became a subject of public discussion ahead of Cyclone Alfred’s approach, but experts stress that tape does not strengthen glass and can create dangerous shatter patterns if windows fail under wind pressure.

Effectiveness of taping

Taping windows is primarily a relic from wartime preparedness rather than modern cyclone science. When wind speeds reach 70 mph (approximately 113 km/h) — the threshold where structural damage typically begins — standard window glass shatters regardless of tape. More problematically, tape can cause broken glass to adhere in larger, sharper pieces rather than dispersing into smaller, safer fragments. Authorities recommend taping only as a last-resort measure when no other protection is available, and never as a primary strategy.

Better preparation methods

Impact-resistant shutters, laminated glass, or properly installed storm screens provide genuine structural protection. For residents without permanent protections, boarding windows with thick plywood — properly sealed at edges — offers meaningful protection against windborne debris, the primary danger during cyclones. The Queensland Government’s Get Ready Queensland programme provides practical preparation checklists beyond the taping question, including securing outdoor furniture, clearing gutters, and knowing your evacuation route. Council’s sandbag self-service centres, commended in the review, provide free sandbags for residents in flood-prone areas, addressing the more immediate flooding risk Brisbane faces from storms like Alfred.

Residents who prioritised sandbag placement and FloodWise monitoring over window tape emerged better prepared for the actual impacts Alfred delivered.

What suburbs are at risk of flooding in Brisbane?

Brisbane’s flood risk concentrates in suburbs along the Brisbane River and its tributaries, with a pattern that repeated across 2011 and 2022. The city’s geography creates a funnel effect where upstream rainfall channels enormous volumes of water through the urban core. Cyclone Alfred’s rainfall fell primarily in already-saturated catchments, triggering rapid river rises.

FloodWise reports

Brisbane City Council’s FloodWise Property Report system allows any resident to enter their address and receive a property-specific flood risk assessment. The service was maintained throughout the Cyclone Alfred event and provides historical flood level data, catchment information, and recommended preparation actions. Areas consistently flagged include suburbs along the Brisbane River corridor and low-lying areas in the city’s western suburbs.

Cyclone-specific risks

While riverine flooding follows predictable patterns tied to river levels, Cyclone Alfred introduced a flash flooding component that caught some residents unprepared. Carindale recorded 144 mm in six hours as the system’s remnants moved through, generating rapid overland flows typical river flood modelling. This type of rainfall-driven flash flooding affects areas not traditionally inundation zones, particularly where urban drainage is overwhelmed by sudden, intense precipitation. Council identified 16 homes for potential buyback under a proposed Commonwealth/State funded Voluntary Home Purchase Scheme — a scheme recommended in the review to address properties repeatedly flooded but where owners prefer relocation over rebuilding.

Which area will be worst affected by Cyclone Alfred?

South East Queensland bore the brunt of Cyclone Alfred’s impacts, with Brisbane at the centre of the storm’s most destructive rainfall. The region had not experienced a tropical cyclone since 1974, making the March 2025 event both meteorologically significant and operationally challenging for emergency managers.

Predicted worst-hit zones

Before landfall, modelling suggested areas north of Brisbane’s crossing point would face the most severe wind impacts, but the actual worst effects came from rainfall rather than wind. Suburbs along creeks and low-lying areas experienced the most severe flooding, with some areas seeing water levels approaching 2022 highs. The Review noted that Council’s public transport response, sandbag distribution, and waste management were commended in the review — operational areas that prevented secondary impacts from compounding the primary flooding.

Post-event assessments

Paul de Jersey’s independent review, published 20 May 2025, found that Brisbane City Council delivered an effective, strong response and recovery effort. “Council had performed very well and the people of Brisbane rose outstandingly to the challenge,” de Jersey stated in his assessment. Lord Mayor Adrian Schrinner emphasised that the review validated Council’s approach: “Review found Council delivered an effective, strong response and recovery effort.” The review made 12 recommendations, including improving disaster recovery funding gaps, advocating for the Federal Enviromon system’s continuation, and refining evacuation centre operations.

The 16-home buyback scheme signals that even an effective Council response cannot fully protect residents in the highest-risk locations, and that structural relocation — not just emergency management — must be part of the resilience conversation.

Review found Council delivered an effective, strong response and recovery effort.

— Adrian Schrinner, Brisbane Lord Mayor (Newsreel)

The review assessed the 2022 Brisbane Flood Review recommendations and Council’s response to the March 2025 tropical cyclone event, determining that all 37 prior recommendations had been “conscientiously attended to.” Council’s approach to public transport coordination, sandbag distribution, and waste management was specifically commended. Recommendations in the 2025 review included refining evacuation centres, advocating for the Federal Enviromon weather system to remain operational, and addressing disaster recovery funding gaps through a proposed Commonwealth/State funded Voluntary Home Purchase Scheme for repeatedly flooded properties.

What comes next for Brisbane’s resilience programme

Paul de Jersey’s review frames Cyclone Alfred as a test Brisbane passed, not a crisis that exposed systemic failure. But passing one test does not guarantee readiness for the next. The review’s 12 recommendations chart a course toward greater resilience — from improving evacuation centre readiness to securing permanent funding for voluntary property buybacks. The Queensland Reconstruction Authority continues recovery operations across the state, while the Inspector-General Emergency Management reviews the broader 2025 weather events including Cyclone Alfred’s impacts on North Queensland, South East Queensland, and Western Queensland.

For Brisbane residents, the practical implications are clear: flood risk persists, window tape is ineffective, and the city’s emergency dashboard and FloodWise systems represent tools worth knowing before the next warning arrives. Council has committed to acting on all 12 recommendations, but the most consequential items — particularly the Voluntary Home Purchase Scheme — require state and federal buy-in that has not yet materialised. The question for Queensland’s disaster planners is whether the political will to fund lasting solutions will arrive before another 50-year event does.
