O'Keeffe is set to officiate France v USA on October 2 and Japan v Scotland October 13.
After the game Michael Chieka seemed less than impressed with O'Keeffe when it came to a number of calls on flanker David Pocock. The Wallabies veteran was pinged three times at the breakdown.
"The stuff on the ground, I'm not quite sure what's going on but the team of three were talking about David Pocock from the first minute of the game," Cheika said.
"I'm not sure what (Pocock's) done but there was some severe focus on him.
"I heard his name mentioned between them on the commentary at least half a dozen times in their own chat when he hadn't even been involved in the ruck."
