I'm Australian and can offer some insight.
I don't believe Aboriginals to be human, I believe they're similar (hence why they can breed with humans) but are closer to simians than humans are. It's illegal to DNA test them in Australia (as the cucked government doesn't want the truth coming out) which is a shame as it'd be interesting to determine what percentage human they actually are. The average IQ of an Aboriginal is 62, which is closer to the IQ of a chimpanzee (40) than that of a white Australian or American (98).
The way they act also supports this, they usually have very limited vocabularies and usually sound as if they're parroting rather than actually thinking about what they say. Aboriginals will often the same few words repeatedly (if they're pissed off, it's usually 'fuck off ya dog cunt' or something along those lines) and without any change in tone, similar to how a parrot would say 'polly want a cracker' or whatever.
They're also, for the most part, completely unable to function in modern society. Few full blooded Aboriginals hold down jobs, and most live in squalor, either on the streets, in makeshift camps or in government housing which they trash. They're known in most outback towns to rip up the floorboards of their homes in order to have a fire inside the house, as well as smashing the windows of the houses when they're angry. I have a relative who used to work in an outback town and he said literally none of the Aboriginals' houses had intact windows, and all of them were in squalid conditions. Keep in mind the squalid conditions aren't because of poverty, they get plenty of welfare money and other help, but because they're just so incredibly lazy they don't want to lift themselves out of their situations. Full blooded Aboriginals often do not use toilets, they're known to just pee and poop wherever they please, and they don't seem to wash or shower very often either (they usually stink). They tend to dress in old rags because they have to (they rarely wear shoes), in Aboriginal settlements it's common for under 5 kids to just run around naked. I'm sure if the adult Aboriginals were allowed to be naked 24/7 they would be, they just don't care about how they look. Their sexual behaviour is also animalistic, I remember a story which said that it was 'common practice' for Aboriginals in some settlements to rape their own children, and that the majority of girls under 12 had been raped by a male relative.
They differ from American blacks as Aboriginals have no aspirations to get out of their shitty living conditions, and are quite happy living like animals. American blacks at least aspire to become rappers and buy the latest Air Jordans and drive Escalades or whatever, Aboriginals don't give a fuck and are happy living in squalor.
Oh, and FYI, all of this applies to the FULL BLOOD Aboriginals, the half caste ones are a different story. Some are successful, hold down jobs etc whilst others are feral, but in a different way. Half caste Aboriginals are similar to American blacks in terms of crime, blaming white people for everything and being on welfare.
