Australian swimming officials said six members of the men's 100m freestyle relay team from the London Olympics had come forward to confess about a controversial team bonding session ahead of the Games.

Swimming Australia said the six, who had talked themselves up as the self-described "Weapons of Mass Destruction" before an embarrassing flop in the pool that saw them walk away without a medal, would reveal all on Friday.

"Swimming Australia can confirm that the six members of the men's relay team have come forward to discuss their involvement in a team bonding session in Manchester prior to arriving in the Olympic Village," the governing body said in a statement on Thursday.
