Australia must learn from mistakes made during its failed London Olympics campaign, the nation's first female Olympic chef de mission says.
Kitty Chiller says improving values within Australia's team is a priority ahead of the 2016 Rio Olympics.
Chiller, who competed for Australia in the modern pentathlon at the 2000 Sydney Games, replaces Nick Green as Australia's chef de mission.
Green did not nominate to continue in the role, citing work commitments.
Chiller's appointment on Friday came as the Australian Olympic Committee (AOC) decided not to penalise swimmers involved in a controversial bonding session before last year's London Games.
Five of the six men's freestyle relay team admitting taking the prescription sleeping drug Stilnox just weeks after it was banned by the AOC.
The swimmers - James Magnussen, Eamon Sullivan, Matt Targett, Tommaso D'Orsogna and Cameron McEvoy - had been previously been fined by Swimming Australia. A sixth relay swimmer, James Roberts, was also fined but denied taking the drug during an ill-fated bonding session.
While they avoided further penalty, AOC president John Coates warned any further troubles would rule them out of the Rio Games.
"This is the yellow card," Coates told reporters in Sydney on Friday.
"The AOC considers that the financial sanction imposed by Swimming Australia is proportionate and sufficient."
The swimmers were under the "misapprehension" they could take Stilnox at the team camp, nine days before they were to compete in London, Coates said.
The swimmers confessed to taking the drug and performing a series of pranks on fellow swim team members in behaviour the AOC found "boorish, selfish, obnoxious and disrespectful", Coates said.
An AOC investigation, headed by Sydney QC Bret Walker, found the swimmers liable for the $150,000 cost of the investigation but Coates said the swimmers wouldn't have to repay the money unless they're caught breaking rules again.
The AOC investigation found the actions of the swimmers harmed morale before the London Games, where Australia failed to achieve its goal of a top five placing on the medal table.
Australia finished 10th with seven gold, 16 silver and 12 bronze medals - the lowest haul in two decades.
"An event like that is never a good event to happen, but you can turn it into a positive," Chiller told reporters in Sydney.
Chiller said there were "very important lessons" to learn from London.
"Team structure is one of them," she said.
"Team structure is related to a focus on high performance and ensuring that we are totally and utterly focused on high performance for the athletes.
"The second one is ensuring that there are strong and prominent and shared values in the team - among staff and also among athletes. And that is something that is built up from now."
