Cooper misses Sevens cut
The 27-year-old flew in from France on Tuesday in a bid to win a place in the line-up as a first step to participating in the Rio Olympics.
But Australia's new Sevens coach Andy Friend said Cooper ran out of time for the sell-out Sydney event.
"Due to circumstances which were beyond Quade's control and our control, he just couldn't get enough work in this week with the team," Friend told reporters.
"There is no doubt in my mind that he will be a tremendous addition to the squad as we build towards Rio," Friend added.
"Quade is going to get his opportunities during the series and we are really excited to have him here in our group and with us throughout this preparation.
"He'll spend the weekend embedded with the squad as well, that contact is a really important part of his learning process in a different version of the game."
Cooper moved to European powerhouse Toulon after a disappointing World Cup and the Mediterranean club have reportedly agreed to free him for three World Series events.
While Cooper sits out the Sydney sevens, fellow Wallaby Henry Speight made the cut for the side captained by a returning Ed Jenkins.
"We've had a great preparation this week and there has certainly been that extra bit of intensity in training ahead of what is a big occasion for the boys playing in front of a huge home crowd.
"There are always tough calls to make regarding selection but we are really happy with the balance of the team and confident that they'll rise to the occasion and produce their best footy this weekend," said Friend.
Australia are seventh in the World Series standings after three rounds of the 10-leg tournament.
Australia squad: Henry Hutchison, Tom Kingston, Sam Myers, Lewis Holland, James Stannard, Con Foley, Cameron Clark, Greg Jeloudev, Ed Jenkins (captain), Allan Fa'alava'au, Henry Speight, Tom Cusack.
