What share of Bundook is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 15.1% of Bundook in high-risk zones for surface flood, with a further 61% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
