Classification isn't really my thing, but I will say Bridie Carter, Rachael Carpani, Aaron Jeffery, Brett Tucker, and Matt Passmore all look "Australian" (although I'm assuming they're Kiwis). Australians/Kiwis have a distinctive look, just as Americans have a distinctive look. Most of the people listed have English surnames, but they're distinctly Aussie/Kiwi in their features to me

And for some very strange reason, even the Italian descendant looks like a typical Anglo-Australian (perhaps it's just her great-grandfather who's Italian?).
* I'm mentioning Australians so much here, because until this thread I only associated the look with Australians.
Edit: So according to Wikipedia, it IS an Australian show. I don't know if the look exists in NZ, then.
