Tbf as a Kiwi (currently in the UK) I see a lot of Australians, when interacting with other cultures, kick up their Australian-ness as much as they can; strengthening the accent, swearing way, _way_ more than they usually would, using "mate" "bloody" etc way more than they do just speaking to me.
I mean when two Australasians speak with each other in a foreign place I definitely hear the accent rise up a bit more outta the both of us but Aussies are something else when it comes to putting on a show, especially when Americans are involved (in my experience).
