Update: The body of a girl missing off an Adelaide beach has been found.
The 15-year old from India was swimming with four other girls at Holdfast Marina, Glenelg on Sunday evening when the group got into trouble.
Lifesavers were able to pull the others from the water but were unable to find the fifth girl despite an extensive search.
Her body was found soon after the search resumed on Monday morning near the breakwater.
Two other girls aged 17 were taken to the Flinders Medical Centre on Sunday.
One remains in a critical condition while the others are stable - another 17 year old in the Royal Adelaide Hospital whose condition is serious and a 12 year old in the Women's and Children's Hospital.
The City of Holdfast Mayor Stephen Patterson says the area is a treacherous spot and there have been drownings before.
"There are signs near the actual breakwater itself alerting people to the fact there are strong currents", Mr Patterson told ABC radio on Monday.
Two boys drowned at a similar spot at Glenelg on New Year's Day in 2016.
Police and Emergency Services have resumed the search for a 15 year old girl who went missing in waters off Glenelg last night.
At around 5.50pm lifesavers were called to the Holdfast Marina where a group of Indian teenagers were having difficulty swimming.
They managed to rescue four - three aged 17 and one 12.
Two 17 year old girls remain at the Flinders Medical Centre, one in a critical condition and one in a stable condition.
Another 17 year old girl is at the Royal Adelaide Hospital in a serious but stable condition.
While a 12 year old girl is at the Women’s and Children’s Hospital in a stable condition.
It's believed the group were here for the Pacific School Games.
Witnesses say scenes on the beach last night were horrifying with hysterical families joining sea and air search teams.
