Hey, asshat! I dare you to disclose to the Aussies, or the Italians, for that matter, to show them this post and then take their pics. Then and only then would this be ethical.
As a side note, I hope they stomp a mud puddle in your ass! I know I would if someone was taking my pic under less than honest circumstances and posting it on the net.
I can't believe you have to ask this question, to tell you the truth.
