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.

"Not only did we win the Gold medal, but it was the competition where I felt like I made my mark within in team and discovered where I fit and how I could contribute to the team," Knox said.

After a disappointing campaign at the 2016 Rio Olympics, where Australia was knocked out in the quarterfinals in a penalty shootout, Knox decided to take time away from the sport to see what she wanted to do.

It ended up being an important decision.

"I needed to get other areas of my life in order, as it had been 12 years of everything taking a back seat to water polo," Knox said.

"Plus after a disappointing result in Rio, I needed to take the time to make sure I was either ready to retire from international sport or return.

"I decided the best way to approach this was to take the time off, returning and getting back to my peak fitness and decide if I still enjoyed the sport.

"I didn’t want the reason that I retire to be because I was scared of the hard work," she said.

With Tokyo 2020 one of the major tournaments coming up in just over two years time, Knox admitted it originally wasn't on her radar but she still enjoys being a part of the team and pushing herself.

"While I don’t want to rush into any decision, as long as I am still challenged and enjoy the sport I definitely see 2020 on the horizon," Knox said.

However, first up for Knox and the Stingers is the FINA World Cup in September, which they are in the middle of preparing with a three-week European tour.
