The Ireland Grand Slammer followed in the footsteps of elder brother Paul by playing in a Test against South Africa in Durban, but ended on the losing side.
Now the Lions have to go to Loftus Versfeld in Pretoria and win to keep the three Test series alive. Wallace wants to be a part of Saturday's revenge mission and firmly believes the Lions can turn things around.
"It was an unbelievable experience to be involved in a Test team. I would love to get another chance," said Wallace.
"We definitely believe we can still do it. We know its going to be very hard to win the next two games, especially at altitude, but there were plenty of positives to take out of the first Test and we have to back our fitness.
"We gave them such a lead at the start and we were always chasing it. That made life difficult for us.
"Their kicking game was very good, but we felt we could do damage when we moved the ball. We've got to start Pretoria as we ended in Durban
"The sense in the crowd was that we could go on and win the game. There was a huge belief building, but then it just didn't materialise.
"But to have come back from where we were and end up within striking distance gives us huge confidence for the next two Tests."
