Not that overseas travel is anything new for Mr Duncan, who is 19.

In 2007 he went to the US to compete in a computer games competition in Seattle.

Mr Duncan has also been to Nepal and Thailand with his family on holidays, and has competed in many other Australian states.

"I started playing when I was at Kirrawee High School after a friend asked me over to his place,'' he said. "We started playing on his computer.''

His speciality is the game Counter-Strike, in which he and four team members get involved in shoot-outs between terrorists and anti-terrorists, alternating sides halfway through the game.

The five call themselves Team Sequential.

Mr Duncan calls himself pupajonN.

In China, he and his teammates, who include Michael Aliferis of Bexley, will compete in the Samsung World Cyber Games.

The team already faced heavy competition in their Sydney qualifier to represent Australia in China.

Nearly a million competitors are registered for what followers regard as the Olympics of their hobby.

Mr Duncan and his team will be flown to Chengdu for the international finals to be held from November 11 to November 15, when they will compete against the world's best for prize money in the six-figure range.

The other Australian finalists for Counter-Strike 1.6 are Sydneysiders Soren Larssen, Rory Burke and Emir Keser.
