Satellite imagery has revealed the extent of the toxic algal bloom affecting South Australia.

Despite its visible spread, an international expert consulted by the state government suggests the situation is not as dire as it may appear.

Dr Donald Anderson, a US-based algal bloom specialist, has been brought in to advise on managing and mitigating the outbreak.

Assessing the situation, Anderson said: “This one is a significant bloom but I would not call it exceptional.”

“We know this is new, we know it’s frightening, but it shouldn’t be.”

He said larger outbreaks had occurred in other regions, including Russia and Florida.

Current efforts are focused on identifying effective strategies to combat the algae.

One method under consideration involves the application of a specialised clay to affected areas, a technique used in China for two decades. 

Anderson explained the process, saying: “As it falls through the water, it’s like a net and it will remove more cells that way, including ones down deep. And that is a technology that’s been used for 20 years in China.”

“It’s something that is managed elsewhere. It will go away at some point. Things will recover.”

Whilst unable to provide a definitive timeline for the bloom’s duration, Anderson assured South Australians that it will eventually dissipate.

The economic impact of the algal bloom is a significant concern.

Premier Peter Malinauskas acknowledged the difficulties faced by affected industries, saying, “It’s a real-life example … that this is causing not just inconvenience but genuine pain and that’s why we are here to help.”
