Coach Wayne Bennett named a 19-man squad, omitting Scott Hill from the side which lost its last Tri-Nations match against the Lions.
Lockyer was a certain inclusion once he emerged unscathed from Monday's game in France while Tate and Kennedy vaulted back into contention with strong performances in Toulouse.
"It's been a tough tour for them," Bennett said.
"That's the third game in about seven weeks now. They have had a good attitude to all their work. Haven't caused any disruption in and around the team. That's all you can ask for."
Tate was outstanding at the weekend and his combination with Lockyer tormented France.
"I just think he had his best game on the tour the other day," Bennett said.
"He ran with a bit more aggression and determination, something he's been struggling with all year in the NRL and certainly a couple of games he's had on this tour. He's a class player, he just hasn't been playing as well as he can.
