I think I remember seeing him for the first time on a series called, "Flamingo Road" back in the late 70's or early 80's. I thought he was mighty handsome as well.
I liked him on Longmire too! Handsome cowboy. I didn't like him hooking up with that tall blonde Deputy chick on the show though.
Settle down, its a show . So hard to believe he is an Aussie and can pull off a western hint of twang
