I don't think it is so much the convict past that makes most Aussies so compliant. (BTW a convict past is not necessarily a criminal past, though there was the odd criminal on the ships! Defying the laws of the crown could have been stealing enough to feed your hungry children in cruel protestant England.) I have a convict heritage of both paternal and maternal sides, and I am certainly am not compliant. I think it's more the fact that, especially in the latter half of 20th century and up till now, Australians have had a reasonably cushy lifestyle and have not had to fight for it. So they tend to naivety and trustfulness when it comes to politics. And the Commonwealth governments have, on the surface at least, been fairly beneficent.
It is necessary also to distinguish between the state of Victoria, which in thrall to China, and other states, which are not quite so. Nevertheless, China has a foothold just about everywhere in Australia and the rest of the world.
