Your maths is correct, this was noticed and documented some time ago and is still occuring. There is no way of telling who is having a look, only the volume and time.
If it is those related to Crossview, then given that the population of NZ and Australia is about 1/20th that would be pretty impressive viewing ratios.
However also consider that the site has been put in front of the Australian govt and opposition, as well as mission boards and churches (the fruits of our labour are paying off

).
If one types in "New Tribes Mission" into google, the official sites come up first but just below them is the "New Tribes Mission Abuse" sites, which is us. Now anyone curious seeing "New Tribes Mission Abuse" would think "hello, hello, hello, what is this about" and have a peek.
Also Europe and Africa are awake while the U.S. sleeps.
It's an interesting discussion that we won't probably ever know the answer too. But considering we have gone from less than an average of 3000 views per day at the beginning of the year and are now about 10,000 views per day, we have done our job well in putting this issue before the masses.
Now back to Crossview. If you google "Tony Abbott" (the leader of the Australian Opposition who wrote that amazing reply), in Wikipedia you will find his biography. It is an interesting read and gives some clues as to why he wants a top level inquiry. If he becomes the next Australian Prime Minister (and the polls suggest he will), lookout paedophiles and their cover uppers.
