Brave 13

WARNING: Graphic content. Kirra-Belle Olsson, from Australia, was surfing north of Sydney when she was attacked by the beast

A brave 13-year-old girl who fought off a shark that bit her TWICE has posted pictures of her injuries online.

Aussie Kirra-Belle Olsson was surfing on Avoca Beach north of Sydney when the metre-long beast approached and took a bite out of her ankle.

She told the Australian Broadcasting Corporation how the shark then went for her calf and tried to drag her from her board and under the sea.

'It just swung me around and tried to pull me under and I saw the tail and ... I really didn't know what to do so I just started screaming.'

Kirra-Belle was so shocked she says she started laughing before she eventually made her getaway and swam to safety.
