Coast swim star denies drug charge

A SUNSHINE Coast swimmer who failed a drug test almost two years ago maintains she has no idea how the banned substance got into her system.

Olympian Kylie Palmer, who moved to the Coast this year, tested positive to a minute trace of a prohibited substance at the World Championships in Barcelona in July 2013.

She was notified of the breach in April and has withdrawn from the Australian swimming team for the upcoming FINA World Championships after being provisionally suspended.

The 25-year-old (pictured) has maintained she has no idea how the unnamed substance came into her system and categorically denies knowingly taking any prohibited substance in Barcelona or at any time in her career.

Swimming Australia said neither it or Palmer was told of the test result until April.

"This week, Kylie has advised Swimming Australia that she has voluntarily accepted a provisional suspension, under FINA's Doping Code," it said in a statement.

"The provisional suspension shall operate until the final determination of the matter by the FINA Doping Tribunal.

"Kylie is entitled to a fair and due process under FINA's Doping Code. This includes ensuring that proper processes are applied to every person affected by this matter.

"Swimming Australia has a duty of care to ensure that we provide Kylie and her family with ongoing support.

"The health and welfare of Kylie and her teammates is important to Swimming Australia and we will ensure they have the necessary personal and professional support."

Palmer first found the spotlight when she finished fifth in the 400m freestyle at the 2006 Commonwealth Games.

She followed that with a gold medal at the 2008 Beijing Olympics in the 4x200m freestyle relay with Stephanie Rice, Bronte Barratt and Linda MacKenzie and backed that up with a silver in the same event at London 2012.
