The most popular British synchronized swimmers are Jenna Randall and Olivia Federici. They represented Britian in duet at the 2008 Beijing Olympics and at the London 2012 Olympics they swam in both the duet and team events.
In 2000, the Australian team and duet swam only because the Olympics were in Sydney and the host nation is automatically a participant. They have not gone to the Olympics since then because they did not qualify.
