As a player he made appearances as a prop and lock for the Wests Tigers and the Parramatta Eels in the NRL and Toulouse in the Elite One Championship.

A former student at St Gregory's College, Campbelltown,[4] Robinson started his playing days in the Sydney Roosters pathways in the Jersey Flegg and President's Cup as an up-and-coming front rower.

[citation needed] After a playing stint with Toulouse Olympique, Robinson, then aged just 28, succeeded Justin Morgan as coach in 2005.

He was an assistant coach with the Newcastle Knights for three seasons (2007-2009) before seeking a release to join Brian Smith at the Sydney Roosters.

He oversaw the team’s defence and in an incredible turnaround, the Club finished the year as runners-up in the NRL Grand Final, after placing last in the competition in 2009.

The Sydney Roosters also claimed successive Minor Premierships and Club Championships under Robinson's tenure and qualified for the Preliminary Final in 2014.

In 2015, the Sydney Roosters became the first team to claim a third consecutive Minor Premiership in the modern era, with the side also qualifying for the Preliminary Final.

With only a few rounds remaining it appeared the club would miss the finals, however they would go on a five-game winning run to secure their position in the Top 8.
