Interaction risk

MODERATE36.7/100

Experimental · uncalibrated

Combined confidence: MODERATE(58%)

Exposure 0.60

Hazard 0.51

Why?

•No live shark detections — this is not an operational alert
•Elevated expected human water use

Shark interaction risk is assessed as MODERATE (public index 36.7/100) with moderate combined confidence. Primary drivers: No live shark detections — this is not an operational alert; Elevated expected human water use. No live shark-detection feed is connected. This is an experimental development assessment, not an operational warning.
