The Australian swimming team's final warm-up event ahead of the London Olympics has been cancelled after two athletes and a coach contracted whooping cough.
Swimming Australia announced that two members of the women's water polo team and one coach have been diagnosed with pertussis, commonly known as whooping cough.
As a result they have decided to cancel the 2012 Grand Prix and relay camp, which was set to begin on Friday at the Australian Institute of Sport in Canberra.
With the Olympics starting in July, Leigh Nugent, Swimming Australia head coach, said the cancellation was purely a precaution.
Nugent said: "We have spoken with the AIS and, whilst we are comfortable with the procedures they have put in place, we have decided to take this precaution.
"Originally we'd planned to have this camp as an opportunity to come together for some further relay preparation and the chance for some of the athletes to race and time trial, a month or so out from the Games.
"From a relay perspective we are confident we're on track with our preparations and will fine-tune things when we get to Manchester in July.
"As for the racing side of things, I'm sure the individual coaches will arrange time trials if they see fit to replicate that preparation."
Members of the Australian Swim Team will now stay in their home states and continue their preparations for London, with the first group of athletes heading to Europe early next week.
The team will next assemble for a staging camp in Manchester from July 14 before heading to London on July 22.
