She won the 50-metre freestyle in a time of 24.59 to record her maiden championship at international level. She also achieved a silver medal in the 100-metre butterfly (57.37). She was a member of three relay teams, the 4×100-metre freestyle relay, 4×100-metre medley relay, and the 4×200-metre freestyle relay teams, winning gold (3:37.22), gold (3:57.47) and silver (7:54.00) in the respective events. Fairly new to the 200-metre freestyle event, Trickett got recorded the then fourth fastest time in history clocking 1:57.06 as lead-off swimmer in the final of the 4×200-metre freestyle relay. The time being more than 1.5 seconds faster than the individual gold medallist Solenne Figuès of France (1.58.60). Trickett did not compete in the individual 100-metre freestyle because she placed third in the event at the Australian championship, but her 100-metre freestyle split times were faster than the individual 100-metre freestyle gold medalist and world record holder Jodie Henry, which earned her the honor of swimming in the final of the medley relay. Despite not competing in the individual 100- and 200-metre freestyle, she did finish 2005 ranked number one in the world in both events. On returning to Australia, Trickett continued her rich vein of form, lowering the 100-metre short course freestyle world record on consecutive nights at the Australian Short Course Championships to 51.70 seconds. 2005 brought a further world record in the short-course 200-metre freestyle at the Sydney, Australia stop of the 2005 FINA World Cup series on 19 November with Trickett recording a time of 1:53.29 to beat the previous record by 0.75 seconds. However, Trickett regained her 100-metre freestyle world record on 31 January 2006 at the Australian Championships in Melbourne. Her time of 53.42 was 0.1 of a second faster than the previous record held by Henry. On 2 August 2006, German swimmer Britta Steffen broke Trickett's 100-metre freestyle world record at the 2006 European Championships in Budapest, Hungary, with a time of 53.30.
