Yep, they both look pretty nice to me. I think the Monaro/Pontiac GTO looks better without the Americanised snout and hood nostrils. The Aussie HSV concept GTS-R is more to my taste, but I'm being picky. I also think that the Mussie would look better in vermilion fire and black, as opposed to the Cobra white with blue. Picky, picky again.
I'd take either just the way they are.
