What share of Broke is exposed to high surface flood risk?
ClimateNest's hazard overlay maps 10.6% of Broke in high-risk zones for surface flood, with a further 62.2% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
