The 14-year-old girl has woken from an induced coma after being stung by one of the world's deadliest jellyfish.
The teenager was stung by the Irukandji jellyfish on Monday in the state's north.
The 14-year-old was stung on the arm while at Nickol Bay in Dampier, she was taken to a hospital in Karratha but later flown to Princess Margaret Hospital where she remains now.
Doctors say she is in a stable condition after coming out of an induced coma.
A WA Country Health spokeswoman told the West Australian said it was the first reported Irukandji case in the Pilbara this year.
