Greg Martin - former Wallabies fullback and current Triple M breakfast radio host in Brisbane - joins Martin Devlin on It's Only Sport, as he does every Thursday. Two simple-minded, middle-aged men talking about MEN'S things that MATTER. This week, Marto and Marty preview the Springboks-All Blacks rugby test in Johannesburg and touch briefly on the Wallabies clash with the Pumas in Argentina, before discussing the Brisbane Broncos in the NRL, the Paralympics in Paris, and more.
