What share of Cecil Park is exposed to high bushfire risk?
ClimateNest's hazard overlay maps 7.8% of Cecil Park in high-risk zones for bushfire, with a further 77.4% in moderate-risk zones. Suburb-level exposure is not uniform — individual properties can differ from these averages, so an address-level check is recommended.
