O’Connor linked up with the squad ahead of Sunday’s (AEDT) match with Ireland and will "help them prepare" after missing the first three games of the Spring Tour.
The 35-year-old signed a deal with the Premiership side towards the end of the Super Rugby Pacific season before bursting back onto the Wallabies scene during the Rugby Championship.
Originally called in for the British & Irish Lions tour, O’Connor delivered a match-winning performance against South Africa in Ellis Park, breaking a drought that lasted close to 60 years at the ground.
He featured in every game of the tournament, including starting against New Zealand in the opening Bledisloe Cup Test.
O’Connor adds further competition to the flyhalf position following Carter Gordon’s return from a quad complaint.
As for Skelton, he was initially expected to join the group, only to injure himself playing for La Rochelle.
Skelton went down injured over the weekend in defeat to Toulon, playing in a rescheduled game from October.
"James O'Connor has joined the squad in Dublin to help them prepare for the Test against Ireland on Saturday," the statement said.
"Will Skelton picked up an ankle injury playing for his club on Saturday and will be unavailable for the team's final two Tests of 2025."
The Wallabies also confirmed Darcy Swain will return home to Australia after serving as lock cover for the past fortnight.
Swain was brought into the squad as a result of injuries to Lukhan Salakaia-Loto (rib) and Josh Canham (concussion) in the win over Japan.
The Australians have arrived in Dublin ahead of a clash with the third-ranked Irish, who are coming off their own victory over the Brave Blossoms.
