In a highly-anticipated season opener, Cousins will face his former West Coast teammate Chris Judd in his first game since 2007.
Wallace confirmed the former Eagle would be thrown right into the thick of things against the Blues and was set to start on the field.
"We expect him to get out and have a real crack, as you would expect from any one of your players," Wallace said on Wednesday.
"We think he has prepared well for the game. We certainly thought he was better in NAB four than he was in NAB two, so he has built up along the way.
"He will be just like any other player and he will try to put his best foot forward and see what happens on the night.
"In his first game, we started him and got him into the action and we'll do the same thing."
Cousins looked ominous as he trained at Gosch's Paddock on Wednesday evening, snapping goals with his teammates in the Tigers' final training session before the big game.
Wallace said the Brownlow Medallist is prepared to go the distance this year after the hype surrounding his first game dies down.
"I spoke to him over in the rooms beforehand and he's ready for the challenges that AFL footy brings," he said.
"As we all know, it's a 22-round affair and Juddy had the same situation last year. He performed well in that game and went on and did a great job for his club.
"It's Ben's turn to go through that process this season."
Before calling an end to questions relating to Cousins, Wallace said the club had expected the near-hysteria that has surrounded this round one match.
He predicted the hype would flare again in time for the Tigers' round 12 clash with the Eagles, but ultimately believed the interest in the talented midfielder would fade.
"We knew exactly what we were taking on and we knew there were going to be some key times," he said.
"Round one was always going to be one of those times and when he plays against the West Coast Eagles, that will be another time.
"But we played up on the Gold Coast and had no one follow us up there for NAB four so I think that's where it will end up eventually. Only time will tell."
