Shark Warning Issued for Swan River After Bull Shark Detections Surge
The Department of Primary Industries and Regional Development (DPIRD) has issued a high-alert shark warning for a section of the Swan River between Melville and Fremantle, urging swimmers to exercise extreme caution. This advisory follows a dramatic spike in bull shark detections, with monitoring devices recording a tagged bull shark up to 77 times in just three days near East Fremantle and Blackwall Reach.
Popular Swimming Spots Under Threat
Blackwall Reach, a well-known swimming destination in East Fremantle where thrill-seekers often leap from cliffs into the water, has been identified as a hotspot for these recent shark activities. Additionally, a bull shark was detected six times under the Stirling Traffic Bridge at East Fremantle between February 20 and 21, raising significant safety concerns for river-users.
Bull sharks are particularly dangerous due to their aggressive nature towards humans and their unique ability to thrive in both saltwater and freshwater environments for extended periods. This adaptability makes them a severe threat in riverine settings like the Swan River, where they can lurk unseen by unsuspecting swimmers.
Tragic History and Increased Monitoring
The warning carries a somber reminder of the 2023 tragedy involving 16-year-old Stella Berry, who was fatally attacked by a bull shark while swimming under the Fremantle Traffic Bridge. This location is less than a kilometre from where the recent detections occurred under the Stirling Bridge. Ms. Berry's death prompted an expansion of shark tagging programs along the Swan River, with data now accessible to the public via DPIRD's Shark Smart website and app.
DPIRD has emphasized that the latest spike in detections elevates the risk of interactions between sharks and people using the river for recreation. The department advises that "additional caution" is necessary when entering the water and recommends that beachgoers adhere to any closures enforced by rangers or Parks and Wildlife officers.
Public Safety Measures and Reporting
To enhance community safety, members of the public are encouraged to report any shark sightings directly to the Water Police at 9442 8600. These reports will be forwarded to local government authorities and updated on the SharkSmart platform, ensuring real-time information dissemination. DPIRD continues to monitor the situation closely, with ongoing surveillance aimed at preventing further incidents.
This alert underscores the importance of vigilance in Perth's waterways, especially in light of historical events and current data trends. Residents and visitors are urged to stay informed through official channels and prioritize safety when enjoying the Swan River's popular swimming spots.
