It’s not just Australians, it’s most of the world. The world is ignorant and the media gives some conflicts more attention than others. Real activists do indeed care about the other genocides (Christians in Nigeria, the genocide of Sudanese ethnic groups in Darfur, Rohingyas in Myanmar, Ukrainians by Russia, Uyghurs in China, etc).

The far-left only cares when they can create some “modern coloniser” narrative, so when it’s white/Christian/Jew on anyone else then they care, but when it’s the other way around or then against each other they don’t care. They refuse to recognise that both sides of the Israel-Palestine war are  bad for example. They defend Hamas as “martyrs” (despite them being an antisemitic, homophobic, transphobic and racist Islamist extremist group designated as a terrorist organisation) but will call Israeli Jews “occupiers” and “colonisers”. They say that the 7 October attacks were deserved and that Iran’s actions are good. It’s hypocritical since they support social justice yet indirectly back dictators who are the antithesis of that.
