Nugent regrets not probing London incident Australian swimming head coach Leigh Nugent says he regrets not following up an incident of "childish behaviour" he became aware of at last year's London Olympics. Nugent, who oversaw Australian swimming's lowest medal haul at an Olympics in two decades, has previously said he was unaware of any cultural problems in the sport. On Tuesday, he denied being aware that prescription drugs were being misused or of a bullying culture in the sport. But on Wednesday, Nugent said he was aware of an incident in the lead-up to the Games. "When we were in Manchester on the Saturday before we moved down to London, on the Sunday it was brought to my attention by a coach and an athlete that there had been some prank calls and some doorknocking," he told ABC Radio. They didn't know who they were. At the time I sort of put it down to childish behaviour ... it didn't raise alarm bells to me, but in hindsight it probably should have raised alarm bells. My regret now is I didn't follow it up. Two separate reviews released publicly on Tuesday condemned swimming's culture and management. It pointed to a failure of leadership and team culture when falling morale was not adequately addressed as the campaign failed to produce the results anticipated. Nugent would not be drawn on whether the outcome would have been better if he'd applied a different leadership approach. If I'd have followed up this doorknocking incident it may have been different, I don't know. Nugent has said he would fight to retain his job, but acknowledged criticism on his part. "I think there's been criticism for everyone and I will wear my share of that as well," he said. I think I've copped a bit. We're trying to make some adjustments now to bring our team into the order that it needs to be in to progress in the next few years. Nugent said he would agree to undertake a three-month leadership program as recommended by the review.
