Notice how little people in the Australia and New Zealand seach against Sky Team. Most people I know of in Australia don't even know who Sky Team are!

I suspect the high numbers of Singaporeans, Kiwis and Australians search again Star may also be partly due to the Ansett incidence and the continual rumours that SQ might start up a new carrier in Australia, etc.

Finally, remember that the figures are normalised so you would expect countries with small populations dependent on air transport to make their way up to the top of the list.
