Tamsin Cook was the youngest swimmer selected on to the 2016 Australian Olympic Team when the then 17-year-old handled the pressure to take home a silver medal.
The West Australian combined with Emma McKeon, Bronte Barrett and Leah Neale in the 4x200m freestyle relay, where she swum the final leg to secure the medal.
In the 400m freestyle she produced a personal best time of 4:04.36 to finish sixth in the final.
The youngster announced herself as star of the future at the 2015 FINA World Junior Swimming Championships. She won gold in the 400m freestyle, was a part of the junior world record breaking 4x200m freestyle gold medal winning team and also won silver in the 200m butterfly. Just under a year out from the Rio Games, Cook set her personal best time of 4:06.17 in Singapore. That time made her the sixth fastest Australian female swimmer in the event.
The South African born athlete moved with her family to Perth Australia at the age of 8 in 2007. In Perth she enjoyed surf club, hockey and horse riding before focusing on swimming.
