Flood risk in Double Bay (2028)

Flood risk in Double Bay (2028) varies significantly at the street level, and understanding that risk is one of the most important due-diligence steps before buying in the Woollahra area. This page draws on NSW flood-mapping data to show which parts of the suburb sit inside a mapped flood zone, what the risk rating means for insurance and mortgage eligibility, and how Double Bay compares to the Sydney-wide average.

A flood-risk rating on its own does not tell you whether a specific property is flood prone. It tells you about the suburb as a whole. Always request a Section 10.7 certificate from Woollahra Council before exchange, as it will disclose any specific flood or overland flow constraints on the property title. Insurers also use postcode-level flood data when pricing premiums, so even low-risk suburbs can attract higher excess in certain streets.
