However, Layne was unable to compete in the final qualifying event due to an injury suffered by her horse, Udon P, forcing her to withdraw.

As the daughter of a Helen Antsee, a Grand Prix rider and FEI judge, Layne was exposed to riding from a young age.

She competed for Australia in the 2006 World Equestrian Games held in Aachen, Germany with her horse, Amoucher - placing ninth in the competition.

[5] In 2013, Layne competed in and won the Hermes’ Cup for the Small Tour championship at the Tokyo CDI3* (international competition).

[10] Layne was chosen to compete in the Olympic Games and would have made her Olympic debut, but had to withdraw from the final qualifying event due to complications stemming from a reoccurring injury with her horse Udon-P.[8] As a result, fellow countrywoman Sue Hearn competed in the qualifying event in her stead,[11] as Layne did not want to jeopardize the team's chances at the Rio Games.

[15] Layne came to the United States in 2007 with her husband, an ex F-16 Fighter pilot in the Air Force who works in the aviation industry.
