The former Australian Women's Water polo captain, known as the Stingers, will make her 350th game milestone tonight against Greece in Spain.

Knox, who is the most capped Stinger, didn't realize her 350th game was coming up.

The 32-year-old has had a career which has spanned almost 13 years at an international level and has seen boundless Olympics, World Cups, and World Championships during her time representing Australia.

Knox started playing water polo as a 14-year-old after after getting tickets women's gold medal match, where Australia won goal, at the 2000 Sydney Olympics

"It was the first proper game I had ever seen, and I remember thinking that this was the sport for me," she said.

"It combined many elements of sport that I loved; water-based, team atmosphere and always changing – no two games are ever the same – always finds a new way to challenge and push you to be a better player,"

A few years later, she had her first game for the Stingers came during a test series against New Zealand in Canberra, which acted as trials for world league and world championship squad which would tour that year. 

"To be perfectly honest, I was just happy to be invited and didn’t really think that I was in with a chance," Knox said.

"I just tried to focus on learning as much as I could and enjoying every moment of being a part of the National Team program," she said.

Since then Knox has gone on to win two-Olympic bronze medals in Bejing 2008 and London 2012, two silver medals World Aquatics Championship, a silver and bronze at the FINA World League Super Finals but her best memory came not long after her Stingers debut.

At the 2006 World Cup, Australia won the gold medal defeating Italy 10-7 in the final.
