After her breakout meet in late 2008, D'Cruz broke her personal best times in several events, also breaking the short course 50 m butterfly world record. At the 2009 Telstra Aus trials, she earned an individual spot in the 100 m freestyle clocking 54.28 along with a spot on the 4×100 m freestyle relay team. The next day she clocked 25.60 s in the 50 m Butterfly, easily making the qualifying time and becoming the third fastest in history in that event, after some thunderous times posted in the semi-finals, the fasted qualifiers failed to match their times in the final, and Guehrer won gold.

At the 2009 World Aquatics Championships, D'Cruz picked up her first medal on day one with a bronze medal in the 4×100 m freestyle relay. With a tremendously fast semi-finals in the 50 m butterfly, from lane 6 Guehrer caused an upset capturing gold.

At the 2010 Commonwealth Games, D'Cruz won silver in the 50m butterfly final to Francesca Halsall and won gold in the 4×100 m freestyle relay.
