Indeed, why would China bring a massive armada to conquer Australia, famously known for being checks notes over 2/3 worthless desert and what? 1k km away from literally everything else that matters?
Also based answer. Stupid reporter: "China is building ships is that not provocation?"
Gee moron what is the US doing then? Never mind everyone else or is China the only ones not allowed to have a military? He should have pointed out all the US bases around the pacific including the occupied Japan/Korean.
Both those countries have regular protests against these bases and yet having them against the will of the natives is not provocation lol.
Anyway Australia is shitty US vassal so none of this is surprising.
The two very different reasons someone says this -
A. They know China has nothing to gain via invasion, and do not want to invade. OR B. They are extremely racist and assume that they might of Australia will triumph.
Actually, they are just smart
Australia would triumph by letting its insane local animals crush any invader
Much like a how a bunch of Emu's beat the Australian army: https://en.wikipedia.org/wiki/Emu_War
That sounds like C -
