Two factors I think: (1) obsessives have a higher likelihood to follow their obsession into immigration-a factor which works to the advantage of certain parts of the US, to the detriment of most of the rest of the world; (2) Australian investors tend to have a more risk-averse attitude, they will offer less money and demand a bigger stake for it, many of them will prefer later stage startups to the truly early stage ones

Lots of factors involved, some more regulatory others more cultural. One is that Australia’s property market has been so hot for so long it sucks up a lot of investment; the US market, while recently being quite hot as well, has historically been much more mixed (the US had a big price drop around the time of the GFC, Australia saw some declines but they were a lot smaller). Another is the US legal system tends to be more borrower-friendly in bankruptcy, foreclosures, etc, making people more willing to take out loans to fund their business ideas
