Asus. Have a gawk at mln.com.au
Thanks EHi Joe
I would personally recommend a Apple Macbook Air 11inch (or if you want to spend a tad more a 13 inch one). This would have to be one of the lightest.
My only word of warning is that you wait a few weeks as it is due to be updated with a more powerful processor.

Asus series of light notebooks is good. i3, i5 in under 1.5kg packages
I myself have an import Toshiba R705 Portege. 1.3kg or so, great little machine, i5, put in an SSD and it flies for the weight.
