Gillieston Heights teenager Maddi Elliott has become the youngest Australian to win a Paralympic gold medal.

The 13-year-old swimmer claimed first place in the 4 X 100 metre freestyle in London this morning along with her team mates Jacqui Freney, Ellie Cole and Katharine Downie in a new world record time.

The teen, who attends Bishop Tyrrell College, has now won a medal of every colour at the games, picking up bronze in the S8 400m freestyle last Friday and a silver in the S8 50 metres freestyle on Monday.

Maddi, who has been swimming competitively since she was diagnosed with cerebral palsy at the age of 4, will compete later this week in the S8 100m backstroke, SM8 200m individual medley and the S8 100m freestyle.
