Australian teenage skateboarding sensation Arisa Trew won the women's park event at the Paris Olympics on Tuesday to become her country's youngest-ever gold medallist.

Trew, 14, nailed a high-risk and high-speed final round in her trademark pink helmet to leap to the top of the rankings, bringing the crowd to their feet at a sun-drenched Place de la Concorde stadium.

Japan's Cocona Hiraki won silver, adding to the silver she won at the 2020 Tokyo Games when skateboarding was first introduced as an Olympic sport, after two typically smooth and high-scoring runs.
