Clarence River
Northern Rivers / Clarence · NSW · Estuary / river-mouth node on the east-coast bull shark corridor
Bull shark conditions
Bull shark ecological conditions are assessed as MODERATE (development model bull-shark-0.1-dev) with very low confidence. This is not an attack probability and is not the mixed-species 0–100 interaction index.
Factors increasing conditions
- Estuary / river-mouth node — bull sharks can use these systems (ecological basis, not a detection).
Factors reducing conditions
- No live authorised bull-shark detections in vShark.
- Seasonal prior for this month is not the peak east-coast inshore hypothesis window.
Uncertainty
- EAC / current velocity is a candidate variable and is not connected.
- Acoustic receiver health is UNKNOWN — SharkSmart/IMOS tracking is not machine-connected.
- River discharge gauges are not connected; rainfall is only a proxy.
Environmental indicators are not confirmed shark observations. This is not an attack prediction and is not the mixed-species 0–100 index.
What has actually been observed
Confirmed shark observations: none in vShark (no live authorised feed).
Environmental indicators (SST, rainfall proxy) are shown in the conditions card. They are not detections.
Surveillance
