A lot of the Aussies you’ll chat to on the internet don’t realise how recent there was heavy segregation even among people broadly considered white now.
If you look at the last names of powerful people even now you’ll find that while they’re general all white dudes Irish last names are underrepresented, despite being around as long as English ones. A lot of migrants from Greece/Italy/Poland etc were heavily sidelined too.
Lets not even get into treatment of native peoples and non white migrants cause we’ll fucking be here all day.
This country is definitely heavily divided by class, last oecd report I read found 4 generation median time for bottom quartile income to next quartile up. That’s bonkers.
