Originally a water-skier, Beretta was a 10-times Australian champion of the sport. He began his media career on Geelong radio station 3GL in 1989, before moving to Triple M Melbourne. Beretta quickly rose up through the ranks of sport broadcasting in Australia through his National Basketball League reports on Network Ten, and in 1995 the Seven Network signed him to a sports reporting role, which he continues today on "Sunrise" and "Seven Early News". Beretta is a fill in for David Koch on "Sunrise" when he is absent.
