Trifiro started his career in the semi-professional lower leagues in Australia, playing in New South Wales for National Premier Leagues NSW clubs Marconi Stallions, APIA Leichhardt and the South Coast Wolves. In 2011, he moved to Victoria where he played the 2011 Victorian Premier League with Northcote alongside his brother, before they both moved to ex-NSL heavyweight South Melbourne in the National Premier Leagues Victoria.
In 2012 Trifiro was signed as one of the inaugural players for Western Sydney Wanderers. In 2014, he signed a one-year extension with the club. Following the 2014-15 A-League, Trifiro was one of a swathe of players released from the Wanderers, following a poor season in which the club narrowly avoided the wooden spoon, finishing 9th.
On 28 April 2016, Trifiro was released by Melbourne City.
The brothers run a football clinic called Futboltec. Its aims are to improve the technical aspects of young players' game, including passing, finishing, and overall awareness.
