Swim stars guilty of drug-fuelled bender to be named and shamed

Some of Australia's best swimmers will on Friday be named and shamed for a drug-fuelled bender just days before the London Olympics.

World champions Eamon Sullivan, James Magnussen, James Roberts, Matt Targett, Cameron McEvoy and Tomasso D'Orsagna will tomorrow confess to abusing a potentially deadly cocktail of narcotics and stimulants.

Seven News is reporting the swimmers took excessive amounts of the insomnia drug Stilnox along with stimulants Red Bull and Coca Cola during a bonding session in Manchester.

The six then went on a late-night rampage through the team hotel, smashing down the doors of teammates.

The cocktail of narcotic and stimulant can be deadly.

Dr John Darcy explains: "They call the effect the Heath Ledger effect. It's a complex mixture of chemicals in the brain that gives a fake high."

Team management were reportedly told of the incident but did not take any immediate action.

Tomorrow's announcement will cause widespread damage to the sport and individuals involved. Seven News understands a number of sponsors have already pulled the pin on lucrative endorsements on the swim stars.

The revelations come just days after a report exposed the "toxic" culture of Australia's swim team in London.

The Bluestone Review lifted the lid on athletes abusing prescription drugs, alcohol and curfews during Games.

Australia won just one gold medal in the pool in London, their worst Olympic performance in 20 years.

Swimming Australia have scheduled a press conference for 1.30pm AEDT tomorrow in Sydney.

Meanwhile, Former Australian Rugby Union chairman Peter McGrath will head a Swimming Australia integrity panel that will look to discipline athletes, coaches and staff in the wake of the damning findings in the report.

Swimming Australia president Barclay Nettlefold encouraged those approached by the panel to be forthcoming with information.

In regards to the 4x100m relay team, it seems that might have already happened.

"We will be decisive, we will be firm and we will discipline athletes, coaches and staff accordingly, where such action is deemed appropriate and necessary," Nettlefold said.

"We want to stop talking about rumour and act on the facts of what did or did not actually occur."

One person under the spotlight is national swim team head coach Leigh Nugent, who oversaw Australian swimming's poor effort.
