Why was outgoing Australian ambassador to the United States Joe Hockey so happy about pulling such a powerful Trump-friendly crowd to his farewell party on Friday night?

The 400 or so guests at the Washington event included billionaire Anthony Pratt, former PM Tony Abbott, golfer Greg Norman, Bret Baier from Fox News, and the president’s acting chief of staff Mick Mulvaney.

Was it because Hockey wanted his successor, Arthur Sinodinos, to meet and greet some important people? Well, no, Arthur wasn’t there.
