Wallace was named in the Ireland squad for their summer tour games against the Barbarians, New Zealand and Australia. In the Barbarians game Wallace started at out-half and gave an accomplished display in Ireland's 39–14 win. Having previously been named on the bench for the test against New Zealand in Wellington the withdrawal of Leinster's Luke Fitzgerald gave Wallace a start in number 12 jersey. He did not disappoint scoring Ireland's only try in a brave 21–11 loss which heralded a return to what Ireland had always been capable of but had been repressed in the last 12 months of O'Sullivan's tenure. Wallace also played in the following weekend's encounter with the Wallabies with Ireland losing the game 18–12.
