The Australian Border Force is working closely with Cameroon officials after eight of the country's athletes disappeared from the Gold Coast Commonwealth Games athletes' village.
Cameroon's Chef de Mission, Victor Agbor Nso, said in a statement on Wednesday five boxers and three weightlifters vanished from their rooms "in three waves".
He said the first three left on April 8, two more on April 9, and three last night.
Mr Nso said the team's officials and remaining athletes, including basketball players and two weightlifters, have left Australia. Cameroon brought 24 athletes to the Gold Coast Games.
The missing athletes are:
Fotsala Simplice - Boxer
Fokou Arsene - Boxer
Ndzie Tchoyi Christian - Boxer
Yombo Ulrich - Boxer
Ndiang Christelle - Boxer
Matam Matam Olivier Heracies - Weightlifter
Minkoumba Petit David - Weightlifter
Fouodji Arcangeline Sonkbou - Weightlifter
Mr Nso said officials have informed Australian police and state officials in Cameroon.
Commonwealth Games chairman Peter Beattie earlier told reporters he was not surprised that some athletes had gone missing, but they hadn't breached their visas.
"It happens at every Games and it’s not a surprise. There is a mechanism in place, they haven’t breached their visas, but it is a manner for their own Commonwealth Games association to monitor and no doubt they will," Mr Beattie said.
“If there is a breach Peter Dutton and the department will deal with it.”
Commonwealth Games Federation chief David Grevemberg said team Cameroon is taking the safety and the welfare of its athletes very seriously.
This is not the first time Cameroon athletes have been reported missing from an international event.
Seven athletes from Cameroon team were reported missing from the 2012 London Olympic Games.
An Australian Border Force spokesperson told SBS News the Department does not comment on individual cases, but visitors to Australia are free to enjoy their stay as long as they meet their visa requirements.
