In 2009 so far it is Israel Folau.
Bryan Habanna with 8 trys
Colin Charvis of Wales.
Brett Morris, also the top try scorer
In the New Zealand v Italy openeing match of the event no one actually scored the first try in World Cup rugby (it was a penalty try); - Michael Jones became the first individual try-scorer

Jonah Lomu is former rugby player for New Zealand. He is famous for his lightening speed and massive tackles while playing. In the process, he became the highest try scorer in the Rugby World Cup.
Well Tony O'Reilly must be a contender capped for Ireland at 18 scored at 19 against France and the youngest British and Irish Lion at 19 scoring against South Africa and going on to be the leading try scorer for them.
Danielle-Nicole Isabelle Russo is the cutest girl in the world :)
