Surfer killed by shark 'died doing what she loved'

The teenager killed in a shark attack while surfing in Western Australia "died doing something she loved", her family said.

The 17-year-old has been named as Laeticia Brouwer and a statement issued by her family on Tuesday said while they're heartbroken by the "tragic accident", they take comfort from the fact she was doing something she loved.

"The ocean was her and her family's passion. Surf was something that she... would do with her dad and her sisters," they said.

"Laeticia will be greatly missed by her family, friends and everyone that knew her.

"We can take comfort that she is now in Heaven with the Lord in eternal peace."

Laeticia was with her father at a popular surf break known as Kelp Beds, near Esperance, when she was mauled by an unidentified shark on Monday afternoon (local time).

She was treated on the beach by paramedics and rushed to hospital, but died from her injuries.

Her mother and her two sisters were also at the beach and were watching on in horror.

St John Ambulance community paramedic Paul Gaughan told local media those on the scene did everything they could.

"It really gave the girl every possible chance under such dire circumstances … unfortunately in this case her injuries were too severe," he said.

Nearby Wylies Bay beach has been closed for at least 48 hours and is being patrolled for any shark sightings.
