Already been mentioned, but Hugh Jackman.
As JD said in Scrubs, (paraphrasing here) "how could you not love Hugh Jackman?!"
The dude is not only talented as all hell, but genuinely friendly and charming, and he's a dedicated family man. He's got several adopted kids and it's not one of those creepy 'Look I have adopted children aren't I wonderful?!" kind of things *eyes Ms Jolie & Mr Pitt*.
Speaking of Brad Pitt, his brother Doug looks pretty cool (from the Virgin mobile ads).
As does that fat guy on the iSelect ads. I'm sure all Aussies recognise him.
