Immigration officers in Australia are hunting for 108 Olympians - including eight Britons - who are illegally staying in the country after their visas expired.
Team members from 61 countries are still in Australia more than two months after the Paralympics finished and three months after the Olympic flame was extinguished, he said.
However, few athletes are among the overstays and none of those wanted by the authorities have been named.
"It's across the board, but I think it's skewed mostly toward officials who have stayed on," said an immigration spokesman.
The biggest group of defaulters is 11 people from the US. Other defaulters include team members from Germany, Russia, Nigeria, Japan, Equatorial Guinea, Cuba and Gabon.
The government wants the overstays to leave voluntarily, but immigration officers are hunting defaulters and would deport them if necessary.
Some 38,000 athletes, trainers, media and other Olympic participants were granted special visas for last year's games, allowing them to stay in Australia until November 1. Another 8,000 people received visas for the Paralympics.
