Actually, Richard there is a better and more accurate measurement,
unfortunately, few have access to it.

That 50% of all Telstra IP user traffic goes via the US (PAIX) via
Telstras 12 racks in-situ.

That 100% of the Telstra IP users are on the plans that Richard

>To extend the example, today's Telstra ADSL plan prices are $29.95,
$39.95, $59.95, $69.95, $79.95, $89.95, $99.95 
>and $149.95; the average is about $75.50.

That each plan has monthly MB download/upload Cap.

That Telstras traffic across the PAIX backbone is an accurate reflection
of 50% of the Australian Internet Users traffic habits.

Then methodology equals, Total CAP from all plans under $50.00 * 100% of
Telstra IP users * 50% >< PAIX in/out traffic.

Suprisingly the answer is a few thousand terrabytes short.

So lets add-in the CAP voilumes of the hifgher plans and divide the
utilisation by 1/8th for each plan.

Still a few thousand TB short.
Its not until we say that 35% of Telstra users are on the highest CAP
plan that the traffic at 50% comes close to equalising with the actual
in/out numbers.

So Richard, without fear of contradiction, I can safely say that if we
assume that 75% of users are on Telstras lowest plan ($29.95) and 35%
are on Telstras highest Plan $149.95 then the average according to the
numbers I have which are:

Total internet. . . . . . . . . . . . . . . . . . . . . . . . . . . .
Total IP & data access . . . . . . . . . . . . . . . . . . . . . . . .
from the TELSTRA PDF Annual Report 2008

A total of 	$4,231,000,000 (including mobile data plans).

I therefore get ARPU's of :

65%	 $249.70 each subscriber.
35%	 $134.45 each subscriber.

Yep - definitely the highest in the world.
