Following the training camp, a series of selection trials were held in Brisbane and Melbourne. In three 100-metre races, Morgan came third, fifth and fourth respectively, with a best time of 1 minute 7.3 seconds. She recorded a best performance of third in a time of 5 minutes 10.0 seconds in the 400-metre freestyle behind Crapp and Fraser. Australia was entitled to three representatives in each individual event, thus allowing Morgan to compete in her first Olympics. Morgan missed out in the 100-metre freestyle as Fraser, Crapp and Leech were selected, but she gained an individual berth in the 400-metre along with Fraser and Crapp. She was one of six swimmers selected for the 4×100-metre freestyle relay squad, the first from Australia to compete at Olympic level. Morgan was placed under substantial pressure by media commentary that regarded her as the weak link in the relay team.
