Olympic champion Sally Pearson is the perfect example of how you can still make it all the way to the top in track and field without resorting to performance-enhancing drugs.
So says Australian head coach Eric Hollingsworth in the leadup to the Moscow world championships, a meet set to be overshadowed by the latest doping scandals in a sport which has already had way more than its fair share of them.
Superstar sprinters Tyson Gay and Asafa Powell are absent form the world titles after failing drug tests, while 31 Turkish athletes have recently received two-year doping bans - several of them teenagers.
Host nation Russia also reportedly has more than 40 athletes currently serving doping suspensions.
"Whenever your great champions, your fast people or your winners are exposed in that type of way, in this modern world of branding and image, we take a hit," said Hollingsworth.
"From my point of view it's all about keeping positive and people like Sally ... show you that we can still do this game clean.
"That's how I keep my head up around it - because if I didn't believe that great champions like Sally were clean then you might as well pack up your suitcase."
Pearson, the reigning Olympic and world 100m hurdles champion, is the stand-out gold medal hope among the 46-strong Australian team in Moscow.
With AFL club Essendon set to receive wide-ranging punishments in the coming days for their controversial supplements program, Hollingsworth also stressed that Athletics Australia (AA) had pursued a "no supplements policy" under his watch.
"We don't go for it," he said.
"Of course some athletes do because they're always searching for something and they might read something on the internet.
"We have no recommendation, we support no supplement company from an athlete's point of view."
Australian middle-distance runner Kelly Hetherington - who will contest the 800m in Moscow - admitted it was unpleasant to have briefly been linked to the ongoing Essendon scandal as her coach is Bombers' football manager and former AA CEO Danny Corcoran.
"Seeing the stress it had on Danny made me stress a little - I just felt so sorry for him," said Hetherington.
"Really to tell you the truth it didn't affect me or didn't affect our training whatsoever - Danny is quite a level-headed, chilled person so I would come to training after something big has broken and I wouldn't be able to tell a thing.
"For us it wasn't really much but it was unpleasant being linked to it in a way.
"I didn't enjoy it, I've done everything right - after my sickness I thought `C'mon this is not what I want' but that's life, you just move on."
Hetherington had asked Corcoran to take over as coach following the sudden death in late 2011 of her former coach and Corcoran's wife Maxine - a request he did not feel he could refuse.
Shortly after Maxine Corcoran suffered the fatal brain tumour, Hetherington was struck down with a bacterial infection which caused paralysis.
