Lisbeth Constance Trickett, OAM (née Lenton; born 28 January 1985) is an Australian retired competitive swimmer.

She married swimmer Luke Trickett among scenes of tight security at Taronga Zoo on Sydney Harbour on 7 April 2007.

[citation needed] Trickett is currently employed by Megaport – an Australian dark fibre carrier – as a National Channel and Partner Manager.

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.

She took 5 of Australia's 12 gold medals in the 2006 Short Course World Championships in Shanghai, being named the leading female swimmer of the meet.

Shortly following the 2007 World Championships, on 3 April, at the biannual Duel in the Pool meet between Australia and the US swimming teams (in Sydney, Australia in 2007), she swam a 100-metre freestyle in 52.99, well under the existing world record of 53.30 by Germany's Britta Steffen, and making her the first woman under 53 seconds in a long-course (50 m) pool.

[10] Trickett went on to officially break the record in a time of 52.88 seconds on 27 March 2008 in the 100-metre finals of the Australian Olympic Trials.

[12] At the Beijing Olympics, Trickett's first final was the 4×100-metre freestyle capturing a bronze medal, despite setting a new Australian record.

Her next final was the 100-metre butterfly in which she captured Gold setting a new Australian record, making her the second fastest in that event in history.

Trickett was ahead of world record pace in the first 50-metre but was overtaken in the last few metres by rival Britta Steffen who captured the gold.

Trickett later contested the 50-metre freestyle (another event she was the world record holder) but did not get on the podium finishing just outside the medals in fourth.

In what was a competitive race at early on, turned in the Aussies favor down the stretch as they captured gold and a new world record.

Trickett had a great start to the 2009 World Championships, capturing bronze in the 4×100-metre freestyle relay, setting an Australian record in the lead off.
