Given that PC power supplies are essentially a world-wide commodity item, I'd have thought that Australia would have inherited any improvements mandated in other jurisdictions, even if there were no local regulations.
But I knocked together a current-transformer, and looked at the current drawn by three PCs and a monitor, (being the input current to a switch-over type UPS when it's not operating in backup mode). What I see seems to be what an un-harmonic-corrected power supply would draw.
