- Melissa Breen narrowly missed the 100m Olympic A qualifying mark by an agonising 0.01s when she ran 11.30s in Japan in March. Breen was relieved to be rewarded for her consistent efforts with Olympic nomination based on selector's discretion. It was her second close-call after running 11.31s in the semi-final at the Australian Open Championship in April.
- Breen now ranks in the top ten all-time list with the likes of Sally Pearson, Raelene Boyle, Cathy Freeman and Melinda Gainsford-Taylor.
- Breen was selected to compete in the 4 x 100m relay at the 2011 World Championships in Daegu where the Australians finished fourth in their heat. Breen placed fifth in the 100m semi-final at the 2010 Delhi Commonwealth Games.
- Breen's long term goal now is to make the 2016 Rio Olympic Games 100m final and break the 11 seconds barrier in the 100m.
- Breen is coached by Matt Beckenham and trains alongside Lauren Boden and Brendan Cole who are competing in the 400m hurdles.
