of course, then there's a question of whether or not such a court case really measures the ignorance of foreigners. If you asked me who the Australian Prime Minister is or what the Australian contribution was to WWII was, I think that might have some significance. A court case concerning a charge of murder versus wildlife running off with a kid (keep in mind a year before I was born) is probably not the most significant thing ever in Australian history. If it is, I can't help but think that perhaps the country has little significance to begin with. After all, I don't expect every American to even remember Lorena Bobbit, the flash in the pan that she was.
But that's just my opinion.
