Robinson was selected in the Australian School Boys side, in 2004.

Robinson made his NSW debut against the Brumbies in the 2006 Australian Provincial Championships.

In 2008, Robinson was part of the NSW Waratahs Super 14 Final team against the Crusaders who were too strong finishing 20–12 in Christchurch.

In his debut season for the Reds, he won the Super Rugby Championship. Unlike his first experience of a Super Rugby Final in 2008, as an unused sub, he was an integral part of the team that won the Super Rugby Final 18–13 against the Crusaders at Suncorp Stadium in front of 52,000. And with that, it earnt his senior call up to the Wallabies.

After being inexplicably released by the Waratahs, and without a Super 14 contract in 2010, Robinson signed an 8-month contract with Italian 3rd tier side, Benevento Gladiators club.

Although signing with the Italian side, Robinson was provided an early release on compassionate grounds after his brother Dan Robinson died suddenly in January, 2010.

In 2010, while playing in Italy, Robinson’s brother Dan had died suddenly whilst visiting on a holiday in London.

The hope would be that when the new franchise, Melbourne Rebels was introduced into the new Super Rugby competition in 2011, Robinson would have an opportunity to come back and show his worth, with the new franchise in the competition.

Robinson after coming back from Italy, and without a club in 2011 initiated contact with his former coach, Ewen McKenzie who was then coach of the Reds.

In 2012 & 2013 Robinson and the Reds made it to both qualifiers, however were knocked out respectively by the Sharks and Crusaders.
