Oz cities top suicide web searches

Apparently Australians are unhappy. I don’t quite agree that you can say this by just referring to this search trend: http://www.google.com/trends?q=How+to+commit+suicide&ctab=0&geo=all&date=all
Google tells us here: http://www.google.com/intl/en/trends/about.html#6

Keep in mind that instead of measuring overall interest in a topic, Google Trends shows users' propensity to search for that topic on Google on a relative basis. For example, just because a particular region isn't on the Top Regions list for the term "haircut" doesn't necessarily mean that people there have decided to stage a mass rebellion against society's conventions. It could be that people in that region might not use Google to find a barber, use a different term when doing their searches, or simply search for so many other topics unrelated to haircuts that searches for "haircut" make up a very small portion of the search volume from that region when compared to other regions.
In other words, people from other regions might not use the specific term 'How to commit suicide'. Maybe other regions prefer to ask 'How do I kill myself' or simply search for 'suicide'. While interesting, you can't read too much into it.
