Chief Executive Matt Carroll said the AOC had received assurances from the National Cabinet, the body that oversees inter-state relations, that no athlete would have to quarantine twice.
He said the AOC had applied for dispensation on the grounds that Olympians were fully vaccinated, had been tested daily and were living in a biosecure “bubble”.
The AOC had been given no reason for the rejection of their application, he said.
“Our concern from the outset has been the mental and physical health of the athletes and we have respected the 14-day quarantine period,” Carroll said on Thursday.
“But without the detailed reasons, it’s very hard to understand why these athletes are being required to undergo this additional quarantine period. A reduction in the period of quarantine would be a good outcome.”
Australian Institute of Sport Chief Medical Officer David Hughes said on Wednesday the extra quarantine period could not be scientifically justified and posed a significant risk to the physical and mental wellbeing of individuals affected.
Through a combination of strict travel and border controls and snap lockdowns, Australia has fared better than many other developed countries during the pandemic, recording fewer than37,000 COVID-19 cases and a death toll under 1,000.
