Flood Damage Restoration Brisbane

Brisbane is the most flood-experienced capital city in Australia. The Brisbane River catchment spans from the D'Aguilar Range to Moreton Bay, and major flood events have occurred in 1974, 2011, 2022, and 2026 (Ex-TC Alfred). The 2011 Brisbane floods inundated 20,000 properties and caused AU$2.38 billion in insured losses.

Ex-TC Alfred in March 2026 generated unprecedented SEQ rainfall, with Brisbane catchments recording flood levels in multiple creek corridors. PERILS confirmed a final Alfred insured loss of AU$1.877 billion. Many Brisbane properties affected by Alfred are still dealing with incomplete remediation or disputed flood vs storm damage classification.

Floodwater from rivers and overland flow is Category 3 water — it contains sewage contamination, chemical runoff, agricultural waste, and biological hazards. Category 3 remediation requires:

• Full personal protective equipment for contractor access
• Removal and disposal of all porous materials in the flood zone (plasterboard, insulation, carpet, soft furnishings)
• HEPA containment and air scrubbing
• Antimicrobial decontamination of all structural surfaces
• Subfloor and cavity decontamination where contaminated water penetrated
• Post-remediation clearance testing

Category 3 events that are improperly remediated (dried only, without decontamination) result in persistent mould growth and potential ongoing health risk.

The peril classification of your damage determines which insurance provisions apply. Brisbane River flooding, Kedron Brook overflow, and overland flow inundation = flood damage (requires specific flood extension in most standard policies). Storm water entering through a breached roof, window, or wall = storm or water ingress (covered under standard storm provisions).

Many Alfred claims involve both — properties that sustained storm water ingress from wind-driven rain AND experienced overland flow inundation. Lodge each component separately. NRPG's IICRC-certified scope assessment clearly delineates flood vs storm components for insurer lodgement.
