I work at more typical software job for an AUS company operating in the US ... AUS workers make less money than the US office but they can rollover PTO indefinitely, right to log off, etc. I think the main reason people come to the US to work from aus is the cost of housing anywhere near the cities is exorbitant and the australian version of the american dream is unbelievably dead.
Interesting that the major cities with sizable public transport user populations are all in the northeast hub. Boston, NYC, Philadelphia, DC. Growing up and living here, cars aren't really necessary day to day in any of these cities. I'm shocked when I travel to basically any other major-ish US city, especially "newer" big cities like Denver, Phoenix, Miami, Tampa. The best way I can describe it is older cities are built at human-scale, newer cities are built at car-scale.
