The 2009 World Junior Championship has already started in Argentina. Australia has 3 representatives playing, Sherab Guo-Yuthok in the Open, Emma Guo and Sarah Anton in the Girls. 3 rounds have been played, with Emma on 1.5/3 and Sarah on 0.5/3. In the Open, Sherab has yet to get of the mark, but I'm assuming some easier opponents will soon be coming his way.
The official website is having problems, so the best place to get results is the ever reliable www.chess-results.com. The link for the Open is here, and the Girls is here.
