No history? Backward? Sexist? ... then let's look at the historical data for Australia... There's a few world first in terms of progressiveness...
World's first universal suffrage of all adults regardless of race, sex, religion, class and property ownership - South Australia - 1894! (*)
World's first full federal suffrage for women - 1902 (NZ had voting first, but Australia included women running for office as well as voting)
World's first woman elected to parliament - 1921
World's first 8 hour day - 1856 - gave women as well as men the right to only work 8 hours per day, unbelievably important.
World's first disabled and old aged pension - 1908 - for all.
World's first universal health insurance system - 1970s (Norway made employers do it first, but this was by a government).
World's first women's hospital staffed by women doctors and surgeons - 1890s, at a time when most countries didn't even allow women to study medicine.
(* Unfortunately it took until the 1960s for Aboriginal people to get the vote in all state, federal and city jurisdictions in Australia, but they could vote in some areas from 1890s.)
And some more recent data....
Australia has the highest number of foreign born citizens of any nation that is not a tax haven, 30% - and the highest of western nations.
Australia's population is 17% Asian, highest of western nations.
UN always rates Australia as either number one or a top ten nation for:
Safety for migrants.
Nation where migrants can reach their potential.
The safest country for international students - with a special mention for African students (by UN)
The world's highest participation of immigrants in politics (by UN)
One of the best places in the world to be a woman (UN)
and one of the least corrupt countries in the world (again, UN).
So yeah, Australia has its share of dickheads, and backward, racist, sexist morons, but as a nation over all? Not worse than elsewhere in the west. Just look at the government it elected in 2025 - landslide to the Left running on a very-pro women agenda.
Melbourne is the best place to live but very expensive - Geelong or one of Victoria's other regional cities might be a good alternative.
