Algae forces closure of Perth beach

A Perth beach will remain closed on Thursday as an algae bloom lingers on the coast. The thick, brown sludge, commonly known as 'Sea Sawdust', stretches three kilometres along Mullaloo Beach. Scientists claim hot and calm conditions caused the phenomenon. Locals say this is not the first time, and it is only going to get worse. Reportedly, the beach is expected to reopen on Friday.
