A warning has been issued for users of a busy waterway after a deadly shark was spotted just a month after a fatal attack on a teenage girl.
On Thursday afternoon, Surf Life Saving WA shared the warning after a member of the public alerted them to a 3m bull shark only 2m off shore.
“Barrack Street Jetty, Perth Metro 2m offshore,” the alert said.
“Large 3m bull shark sighted between the 4th and 5th jetty berths.”
The shark sighting comes with Perth residents already on high alert after Stella Berry, 16, was fatally attacked by a bull shark in February.
Stella, a student at Shenton College and the daughter of two high school teachers, was playing with friends in the Swan River in North Fremantle, near the Fremantle Traffic Bridge, on a Saturday afternoon when she was attacked.
Emergency services were called about 3pm; however, Stella died at the scene.
Horror screams were heard from the water before anyone noticed the shark.
Witnesses said a heroic bystander jumped into the water to try to save Stella and bring her back to shore.
The horrific attack was the first fatal attack in the Swan River in more than a century.
Days later, a local fisherman caught a 3m bull shark in the same river.
Kai Boyle cast out his line not knowing he would attract the beast.
“It didn’t come from the ocean it was in the river swimming past,” he wrote on Facebook.
“They may potentially be dangerous to others and people can’t get there head around how big they get in the Swan River right here in Perth.”
Shark attacks are still considered rare in the Swan River, with the last attack killing a young schoolboy in Peppermint Grove on January 27, 1923.
