Redland City Council has installed signs at Thompson’s Beach, Victoria Point and Coochiemudlo Island’s Main Beach to advise residents and visitors of the presence of Lyngbya (Lyngbya majuscula), a naturally occurring, blue-green algae that can cause skin, eye and respiratory irritations if people come into contact with it.
The presence of Lyngbya is not uncommon for the waters of Moreton Bay, and all Redlands Coast beaches and waterways remain open for recreational use.
The signs are precautionary only to inform people of the presence of the material, which often presents as mats floating on the surface of the water or as washed-up clumps on the beach.
Swimming and wading is not recommended where algae is present; and Council urges residents to be mindful that Lyngbya could also be present at any beach.
Council will continue to monitor all Redlands Coast beaches, and will erect signs if Lyngbya is found elsewhere.
