Who's Andy Warhol POP ART Painting Portrait is This?

One of my favorite aspects to Andy Warhol's art are the many portraits he did of famous and/or rich people. These Pop Art paintings have become icons in the art world & the "style" is copied by many graphic artists today. Here are 2 examples of one such portrait. Now, the thing that's driving me crazy is I got this picture ( and was gonna publish the information ) from an Australian Government website but I totally forgot the name of it & lost the bookmark! This guy was a high official for their government & had his portrait done. Arrrggghhh, oh well, you can still enjoy it's beauty, ha ha!
