Annan was born on 12 June 1973 in
Wentworthville, New South Wales. She was voted the
Best Female Hockey Player in the World in 1999. In the following year, she led the Australian team to gold at the
2000 Summer Olympics. She subsequently retired from international competition and moved to the
Netherlands. In the Netherlands she played for
HC Klein Zwitserland from
The Hague. She retired in 2003, becoming the coach of Dutch league team
HC Klein Zwitserland. In 2004, she was an assistant of Dutch Head Coach
Marc Lammers at the
2004 Summer Olympics in
Athens, Greece, when
the Netherlands won silver. Annan was married to Argentinian hockey player,
Maximiliano Caldas. Their second son, Cooper Thate, was born in October 2008. Annan was to be the coach of the first women's team of the
Amsterdamsche Hockey & Bandy Club during the 2012–2013 season. In 2013 Annan was inducted into the
Sport Australia Hall of Fame. In October 2015 she was named as head coach of the
Netherlands women's team, succeeding Sjoerd Marijne. Annan's former husband Max Caldas previously coached the Netherlands women's team to a gold medal at the
2012 Olympic Games. During the
2016 games in Rio de Janeiro Annan coached her team to a silver medal losing to the Great Britain Team after shoot-outs in the final. In 2022, Annan was fired as coach of the Netherlands women's team after an investigation into accusations of verbal
intimidation and creating a
culture of fear and
silence. However, according to one Dutch hockey commentator, there was an internal divide within the team about how to achieve the team's objectives: "There were two currents within the Dutch team and the question was which one would come out on top" (English translation of the Dutch original). Several experienced players reported the decision had been made without consulting them, using hockey.nl to express their support for Annan and describing her as a "fantastic coach" (English translation of the Dutch original). Annan chose not to comment publicly, beyond releasing a statement that "In recent months I have gained insight into the points that we as a team, staff and individuals could work on. In my opinion, there is no difference of opinion about what can be improved, but there is about the approach to it. I have drawn a line for myself there and this is unfortunately the consequence" (English translation of the Dutch original) [https://nos.nl/artikel/2412829-bondscoach-annan-ontslagen-bij-hockeyvrouwenploeg-na-berichten-over-angstcultuur. ==Major international tournaments==
