Test results for a potentially fatal organism, believed to have contaminated a popular swimming spot in Western Australia, have been returned.
Earlier this month, the Shire of Waroona issued an alert after naegleria amoeba was detected in the water at Drakesbrook Weir, located south of Perth.
However, test results have since returned, confirming there is no presence of the deadly Naegleria fowleri, commonly known as the "brain-eating amoeba".

Temporary health warning signs were posted around Drakesbrook Weir to alert swimmers of the potential risks.
It's understood that this is the third time the weir has been closed this year over amoeba risks.
According to WA Health, amoebic meningitis thrives in warm, stagnant water and, if inhaled through the nose, can lead to a rare and possibly fatal infection called amoebic meningitis.
Children are at most risk of the disease, which causes inflammation and eventual destruction of the brain and brain linings.
Drakesbrook Weir is a popular spot for locals, featuring a pontoon in the water that children use to jump in.
