Can't. American Playstation 2's are designed for Amercian power points which put out less (or is it more) volts than the power points found in Australia.
There are different kinds of 'power':
220 - 240 volts (can be 230 in some countries)
50 or 60 hz (or Hertz or Cycles)
Volts in the pressure at which the 'power' (the real power is the amps) is pushed.
Hertz or Cycles is the rate at which power is generated, but can also be described as the amount of times AC current switches on and off (DC = Direct current always going in one direction, AC = Alternating Current, constantly switching on and off, back and forth).
In the States they run:
110 V, 50hz
In NZ (and possibly Australia) we run:
230V, 50hz
In Japan they run:
110V, 60hz (some areas are 50hz)
With a huge machine, the change between 50 and 60 hz is noticeble with the speed. But with small appliances, like a PS2 the only noticble thing is the heat that it puts out, and it will eventually blow up.
Overcoming this problem is hard, but however, it is very easy to find a power point converter (seen some at the airport lastnight)

Sorry about this.
But my Dad is an electrician and he explaind it to me a few weeks ago because we (me and my mum) are going on a holiday to Hong Kong and Singapore (we leave on the 21st Sept get back on the 4th Oct)and I wanted to know if I could buy a Ps2 in hk or singapore. But obviously I cant because
A) they are NTSC, here in NZ we are pal
B)they have a different power supply.
Well thank you very much, I now have sore wrists and sore eyes **bows**
