Flood exposure across Wahroonga (2076) is sourced from the NSW State Environmental Planning Policy (Resilience and Hazards) 2021 datasets and the relevant Ku-ring-gai Council flood study. The rating reflects the likelihood and depth of flooding based on modelled rainfall events, not historical flood records alone.
If Wahroonga shows a moderate or high flood-risk rating, that does not necessarily rule it out as a purchase. Many highly desirable Sydney suburbs carry some flood exposure. What matters is the specific land parcel: is it in a high-probability zone, a low-probability zone, or outside mapped flood area entirely? Your conveyancer can obtain that answer from the Section 10.7 certificate. Flood-risk ratings can also affect lending conditions, so discuss the rating with your mortgage broker before committing.
