The Lions have dismissed suggestions of paranoia after a row about whether they accused Australia of spying on them.
On Sunday, Lions head coach Warren Gatland was forced to clarify his comments earlier in the week about Australian surveillance.
But Wallabies boss Robbie Deans accused the tourists of creating a sideshow.
Assistant coach Andy Farrell said: “We are not paranoid. If we are paranoid about getting things right then yes, we are. You’ve got to get things right.”
The Lions, who beat Queensland Reds on Saturday in their toughest game of the tour so far, reportedly have security guards at their training ground.
