Chief executive Dallas O'Brien has acknowledged Athletics Australia can do more to assist athletes in fulfilling their obligations to the sport's drug-testing regime.
Commonwealth javelin champion Jarrod Bannister revealed on Thursday that he had been hit with a 20-month suspension following a Court of Arbitration for Sport hearing.
Bannister admitted to missing three out-of-competition doping tests in the space of 18 months - which the World Anti-Doping Agency considers the equivalent of a failed test.
But CAS found there was no deliberate attempt by Bannister to miss the third test, cutting his ban from two years to 20 months.
O'Brien said athletes competing in a number of Olympic sports had to be meticulous in always providing their whereabouts to drug-testers - an obligation Bannister admitted to taking lightly at times.
"We are disappointed that Jarrod did not meet his obligations as one of our top performing athletes and this case demonstrates the need for all athletes to be diligent and responsible," O'Brien said.
"Part of this is that it is the individual athlete's responsibility to notify the World Anti-Doping Agency of all international travel arrangements and precise accommodation arrangements.
"We acknowledge this can be challenging once the athlete is already overseas and perhaps we need to look at how we can do a little more to assist the athletes in those circumstances to fulfil their requirements."
The ban will last until February 18, 2015, after which time the 28-year-old Bannister plans to return to competition.
"Within the court reasons, it was found that there was no deliberate action by myself to avoid being tested, that finding is consistent with my defence submissions at the hearing on the 21 June 2013," said Bannister.
"I respect the award issued by Mr Alan Sullivan SC , naturally I am still deeply disappointed at receiving the period of ineligibility."
Bannister called on AA, WADA and the Australian Sports Anti-Doping Authority and WADA to review their operations as "there are deficiencies in the way these organisations go about their business".
In a separate incident in late 2011, Bannister was banned from receiving support from any of the Australian institutes of sport following a funding breach.
In addition to winning the gold medal at the 2010 Commonwealth Games in Delhi, Bannister was a finalist at the 2008 Olympics and the 2011 world championships.
