← East coast corridorEast GippslandMOCKAssessed 21 Sept 2026, 4:05 pmModel 0.1.0-dev

Temperate range-edge

Victoria is represented as a temperate range-edge. Bull-shark thermal suitability is typically low here. White shark / bronze whaler / sevengill assemblages dominate. A Moreton Bay current hypothesis does not extrapolate to Port Phillip.

Bull shark conditions

LOWConfidence VERY LOWbull-shark-0.1-dev

Bull shark ecological conditions are assessed as LOW (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 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.

Range-edge node. Temperate SST. Bull sharks are not treated as a regular assemblage; white sharks more relevant.

Why?

  • No live shark detections — this is not an operational alert
  • Missing SST reduces model confidence

Shark interaction risk is assessed as MODERATE (public index 24.5/100) with moderate combined confidence. Primary drivers: No live shark detections — this is not an operational alert; Missing SST reduces model confidence. 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.

Victorian temperate range-edge. Bull-shark thermal suitability typically low. White shark / bronze whaler / sevengill more relevant. Not a Moreton pulse extension.

Recent detections / sightings

No shark observations are stored for this location. That is a data gap, not evidence that sharks are absent. SharkSmart WA is not machine-connected.

CACHED rows are curated public notices, not a live tagged-shark feed, and do not enter the 0–100 as live detections.

Environmental state

No environmental observations stored yet. Open-Meteo ingest writes to a regional centroid.

Human exposure

Estimated, not observed counts. No false precision.

Persistent spatial context

  • inlet
  • beach
  • estuary

Geomorphology is persistent context, not a transient observation.

Data gaps

  • sea surface temperature
  • turbidity proxy
  • live detections
  • recent detections

Missing data reduces confidence; it does not mean low risk.

Data coverage

Where vShark knows little is as important as where it knows more. Missing coverage does not mean low risk.

  • Shark observation coverageNONE

    NSW SharkSmart is not connected. MOCK detections do not enter the score.

Evidence hierarchy

  1. Direct recent detectionTagged receiver, verified instrument detection, or equivalent in the relevant window.
  2. Verified sightingSighting confirmed by a responsible authority or trained observer.
  3. Multiple corroborated observationsIndependent reports that agree in space and time.
  4. Strong ecological proxyPrey aggregation, carcass, or similar with documented association — still a proxy.
  5. Environmental habitat suitabilityTemperature, depth, and similar suitability — not presence.
  6. Historical seasonal associationClimatology / phenology prior. Not a live observation.
  7. Long-term background prevalenceBaseline occurrence in the region. Weakest for now-casting.
