caused by a back misalignment prevented her from using the optimal flip turn preferred by freestyle swimmers. Instead, she was forced to utilise the touch turn, which was slower. National selection In August 1955, Leech set an Australian record of 1 minute 5.0 seconds for the 110-yard freestyle, before lowering it to 1 minute 4.8 seconds in October; this prompted newspapers to trumpet her as a prospect for the Melbourne Olympics. She did not get an opportunity to defend her Australian title in 1956 because she was hospitalised with illness. Leech recovered in time to win the national age title in the 100-metre freestyle in a time of 1 minute 4.6 seconds, just 0.1 of a second outside Dawn Fraser's world record. She then posted a time of 1 minute 4.6 seconds to defeat Fraser and Lorraine Crapp at another meeting in the following month. Leech was named in the Olympic squad and the Australian Swimming Union exempted her from travelling to the national training camp in Townsville so she could train with Froelich, who understood her special dietary requirements. She joined the squad for the final race trials in Melbourne in October before the Olympics. Fraser and Crapp were too strong in the 100-metre freestyle, with Leech finishing second and third in the two races. After combining with Fraser, Crapp and Margaret Gibson to break the world record for the 4×100-metre freestyle relay, Leech was selected as one of Australia's three entrants in the 100-metre freestyle events and one of six swimmers for the 4×100-metre freestyle relay squad for the Olympics. International career Having arrived at the Olympics, Leech made her debut in the 100-metre freestyle, an event in which she, Fraser and Crapp were regarded as the three strongest competitors, although the latter two were considered to be substantially stronger. All three won their heats. Leech won her heat by 1.6 seconds in a time of 1 minute 4.9 seconds. She was third fastest qualifier behind Fraser and Crapp, who were over 1.5 seconds faster. Drawn in Fraser's semifinal, Leech finished second in a time of 1 minute 5.2 seconds, and was the third fastest qualifier for the final behind her compatriots. The semifinals followed a similar pattern to the heats, with Fraser and Crapp more than two seconds ahead of the six remaining qualifiers, who were separated by just 0.8 of a second. This pattern was repeated
