Allianz Aust v Canberra Pools

Allianz Australia Insurance Limited (Allianz) appealed to the High Court of Australia against a decision of the Full Federal Court concerning the interpretation of a contract of insurance. The dispute arose from a claim made by Canberra Pools Pty Ltd (Canberra Pools) under a public liability insurance policy issued by Allianz, following damage to Canberra Pools' property caused by a flood. Allianz denied liability, asserting that the damage was excluded under the policy.

The High Court was required to determine whether the damage to Canberra Pools' property was covered by the public liability insurance policy, notwithstanding exclusions relating to flood damage. Specifically, the court had to consider the proper construction of the policy wording, including whether the damage was caused by an "event" as defined in the policy, and the application of exclusion clauses to the circumstances of the loss.

The High Court held that the damage was not covered by the policy. Their Honours, Gummow and Hayne JJ, reasoned that the policy's exclusion for damage caused by flood was clear and unambiguous. They found that the proximate cause of the damage was the inundation of the property by floodwaters, and therefore the exclusion applied. The court rejected arguments that the damage was caused by an insured peril, such as a burst pipe, which might have been indirectly related to the flood but was not the direct cause of the loss. The appeal was allowed, and the decision of the Full Federal Court was set aside.
