The pair will also lead as two of the nine competing team members.

Amberger and Bombell, both from Queensland, won a bronze medal as a duo at the Commonwealth Games in Delhi and were members of the team which finished seventh in the 2008 Beijing Olympics.

"Sarah and I are very excited and hope to perform well for Australia in the duet," Amberger said.

"We have two new routines since Delhi, which are more dynamic and more impressive, and we hope the judges like them."

The 25-year-old is delighted with the makeup of the team, saying: "This is a different team, a lot younger, but we are working well together.

"We have choreographed our routines for London and it's going well."


The other seven members of the team range in age and experience, from 16-year-old school student Olga Burtaev to 27-year-old Beijing Olympian Tarren Otte (pictured below).

Otte originally announced her retirement from the sport after narrowly missing a medal at the Commonwealth Games in Delhi, but decided not to miss out on London 2012, and today secured her place on the team.

"I did retire after Delhi and had a year off, but I have lived in the sport for so long and I love all the girls so I thought I can do one more," Otte said.

"We finished seventh in Beijing and we would love to finish seventh or better in London."


Also in the team are Otte's Beijing teammates Tamika Domrow and Samantha Reid.

Making their Olympic debut will be Burtaev, Jenny-Lyn Anderson, Bianca Hammett and Francesca Owen.

Synchronised swimming will take place at the Aquatics Centre at the Olympic Park.

The duet event is from August 5 until 7 and the team event is on August 9 and 10.
