Hind, a Summer Clerk at the Allens Arthur Robinson Sydney office argued with Croke against the proposition "That the media should show the full horror of war" against 240 teams including Harvard, Oxford and the London School of Economics.

It's the fifth time the University of Sydney has taken out the prize, having most recently won in 2007

Professor Gillian Triggs, Dean of the Sydney Law School, said in a statement that the win represents the talent residing in law schools.

"Steve and Christopher have shown yet again how talented Australian law students are on the world stage. We wish them well in their future careers," she said.

The win places Hind as the second-best debater in the world and Croke in the fifth spot.

Part of the debate from Hind and Croke revolved around the argument that there is a distinction between knowing what happens in a war and reading about it: "And having the visual reaction that people have to seeing their loved ones brutalised and broadcasted across the world... stopping us from fighting the wars well," Hind said in his speech.
