I would not buy the Cisco supply.  I use the 3com 3cnjpse on most of our 
Cisco 7940g and 7960g phones.  They are available in the US for less than 
$20 each.  You need a custom wired Cat 5 cable (easy) from the power 
injector to the phone but this allows one less cord plugged into the back 
of the phone cluttering your desktop.  My injectors are labeled: Input 
100-240v  50-60hz 500ma, output 48vdc 400ma.  They should work 
anywhere.  You would need to supply the localized power cord for Australia 
if you bought them from the US.

The price is good here but ignore the power specs as they are wrong.
