Why?

•No live shark detections — this is not an operational alert

Shark interaction risk is assessed as MODERATE (public index 27.5/100) with moderate combined confidence. Primary drivers: No live shark detections — this is not an operational alert. 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.
