[2] She rose to prominence as a junior, becoming the first South Australian to win a triple crown at a national event.

[5] Choo has represented Australia multiple times including at the 2006, 2007 and 2009 BWF World Junior Championships.

The pair almost staged an upset in the quarterfinals against the number one seeds from Singapore, Yao Lei and Shinta Mulia Sari.

Choo and Veeran competed at the 2011 BWF World Championships in London where they reached the second round.

The pair demolished Steffi Annys and Severine Corvilain of Germany 21–6, 21–9 in the first round before losing to 10th seeds, and eventual bronze medalists of the 2012 Summer Olympics, Valeria Sorokina and Nina Vislova of Russia in three games.

Choo and Veeran therefore advanced to the quarterfinals, where they were defeated by Alex Bruce and Michelle Li of Canada.
