While the setback saw him overlooked for the Wallabies domestic Tests, Chisholm returned to the international fold during the 2009 Tri Nations Series, again establishing himself in the Australian starting XV.

His strong lineout winning ability, aggressive physicality, barnstorming running and frequent try-scoring has formed the cornerstone of his success throughout his career.

In addition to his Super 12 title, Chisholm was named the CA Brumbies' 'Best Forward' and runner-up to George Smith in the Brett Robinson Award in 2007, and is currently the club's second most-capped lock behind David Giffin (80 caps).

The following season he made his debut for the Wallabies in a test against Scotland in Edinburgh and was subsequently named in the 22 against France the following week and went on to start at lock for Australia A against the French Barbarians in Paris.
