His name is David Thornton (mentioned in the article, if you bothered to read it before commenting). Not 100% conclusive, but pretty strong evidence of being white, as Thornton is an English/Scottish name.
FWIW, as a nonwhite person myself, I think that accusing someone of racism for assuming David Thornton from Australia is white is beyond idiocy.
eh. racism is an umbrella term for being prejudicial and discriminatory based on a persons race. while definitely being prejudicial it certainly wasn't discriminating.
also - article has a big photo of this guy's gormless white mug ;)
also - he's from Sydney, so probably a wanker as well.
