It emerged then that he will need to gain Australian citizenship to play for the sevens team at the Olympics in August, Fairfax reports.
Under Games rules, all athletes must be citizens of the country they represent.
Cooper now faces an Australian citizenship test that every applicant must pass.
"He needs to sign those documents to become an Australian citizen and get an Australian passport," Australian sevens coach Andy Friend said.
"Once he's got that, then he is eligible. Then he has to go through the playing side and make sure we pick him."
An Australian Rugby Union spokesman said Cooper had still not completed his citizenship application.
But if Cooper is thinking of switching his allegiance to the land of his birth so he can play at Rio, he can forget about it. Sir Gordon gave that notion a very firm thumbs-down.
