A noxious algal bloom off the coast of South Australia’s Fleurieu Peninsula is causing widespread health issues for residents, with reports of flu-like symptoms, eye irritation, and even asthma attacks as a result of the airborne particles. 

The bloom, which stretches from Victor Harbor to Goolwa, has led to marine life washing up dead, and is now affecting residents living kilometres away from the beach.

“It hits the back of your throat. You’re coughing. You get a tight chest, eye irritation,” local resident Mickey Mason said.

“I’m getting complaints from people that are up to a kilometre away from the ocean themselves where they live and they’re feeling unwell most of the time,” said local MP David Basham.

“We’re seeing people wear face masks and they say that helps,” he added.

The bloom has been present for over three weeks. 

“It’s devastating and it’s scary, no one knows what’s going on really,” Mason said.

While doctors believe the current algal bloom doesn’t produce toxins harmful to humans and shouldn’t cause long-term effects, residents claim the immediate health impacts are undeniable. 

“I’ve had at least three people contact me that they feel the irritation has led to an asthma attack,” Basham said.

Local businesses are hoping the smell and effects of the algae will be gone before people head to the area for Easter next week.

“I hope people don’t change their travel plans,” said Luke Talbot-Male, a local resident. 

“There’s still lots to do on the Fleurieu Peninsula. It’s really important people keep coming here and having a great holiday.”

The environment minister has said the bloom is unlikely to dissipate until the area experiences strong westerly winds, which typically begin around the end of April.
