Perth girl blinded after water park visit

The WA government could be sued by the family of a five-year-old girl who has been left partially blind in one eye from an infection after visiting Perth's bacteria-plagued Elizabeth Quay water park.

Preschooler Chelsea Fawcett visited the water park and soon developed a serious eye infection.

After staying in hospital for several days, doctors have now told the family Chelsea is partially blind in one eye and it is unknown if her sight will ever return to normal.

The water park remains closed indefinitely after the Health Department's routine sampling detected bacteria in water spray and amoebae in waste discharge pipes.

Chelsea's mum Jannah Fawcett said she just wanted to take her daughter to see the new park and have fun but now she may be left with a lifetime disability.

"They should have tested that water, and not opened it before they knew it was safe," she said.

"It has been an awful experience with Chelsea in hospital and now she has to wear an eye patch and may never get her normal sight back."

Slater and Gordon lawyer Alex Illich said the firm was investigating a claim on behalf of Chelsea Fawcett against the state government as the operator of the water park.
