The young woman was walking on St Kilda’s pier in Melbourne, staring at Facebook on her mobile phone, when she overstepped the boardwalk and fell into the cold water.
Two people walking past saw her slip and called the police, who rescue thed woman.
When they got her out of the water, police said she was still holding her phone.
Senior Constable Dean Kelly told The Age newspaper: ”She wasn’t splashing around too much. She wasn’t in a panic even though she was in the water for probably 20 minutes. The woman had a backpack on, which may have helped her to stay afloat; she wasn’t a good swimmer, but she was floating OK on her back.”
