I found this by accident,
Amazon UK has listed the price of PS4 at 349 GBP. However when I attempted to check out, it came up around 299 GBP delivered! - that's around $AUD 491!!!!
I guess this find suits those who can't wait for the price of PS4 to drop. I believe that UK voltage is the same as OZ.
Amazon US is offering a cheaper price at $US 415 and they deliver to Australia as well, but I believe the voltage is different to ours.
JB-Hifi - PS4 pre-order is $AUD 548
EB Games - PS4 pre-order is $AUD 549
You may want to consider warranty for a new console with no information on hardware issues and faults.
Yes, this is a great deal but for $60 more you get your standard warranty and an easy RMA process if it fails .
