Interaction risk

MODERATE37.2/100

Experimental · uncalibrated

Combined confidence: MODERATE(58%)

Exposure 0.60

Hazard 0.52

Why?

•No live shark detections — this is not an operational alert
•Water temperature (~19.9°C) favours great white shark thermal suitability
•Elevated expected human water use

Shark interaction risk is assessed as MODERATE (public index 37.2/100) with moderate combined confidence. Primary drivers: No live shark detections — this is not an operational alert; Water temperature (~19.9°C) favours great white shark thermal suitability; Elevated expected human water use. No live shark-detection feed is connected. This is an experimental development assessment, not an operational warning. Always follow lifeguard instructions, beach closures, and official NSW SharkSmart advice. vShark is not a government or SLSA product.
