Episode notes
Storms Create Shark Hotspots
- Heavy rain, warm water and sewage overflows combine to pull bull sharks close to shore and surface-bait.
- This environmental confluence explains the recent cluster of Sydney shark bites.
Bull Sharks Follow Bait And Sewage
- Bull sharks follow bait fish drawn to sewage and warm temperatures, moving into shallower waters.
- This seasonal and pollution-driven behaviour raises bite risk near popular swimming spots.
Wait Before You Swim
- Avoid swimming in harbours for 72 hours after heavy rain and at ocean beaches for at least 24 hours.
- Authorities should warn the public clearly about these waiting periods to reduce bite risk.
