As an Irish person, I have the impression that Australia is very similar to Ireland in this regard. I came across a survey years ago that asked a question along the lines of "in the workplace, is the manager/boss higher status or equal to the staff they manage?" (paraphrasing because it was years ago). Ireland scored amongst the highest that said the boss and other staff are equals. I imagine Australia would too, while the US would score lower on that scale (as did some other EU countries).
I now live in Vietnam, and somehow I've ended up being the boss, with a team of around 20 Vietnamese people. While they are diligent and skilled workers, the level of deference they show to me makes me deeply uncomfortable and I have to keep reminding them to talk to me like a human being - call me by my name instead of "sir", for example. But it's a losing battle.
