individual,

Better still let's just cancel all the Chinese's visas and piss them off back to China.

cancel all the Chinese's visas
Mr Opinion,
Many have been here longer than you, but I do agree that Immigration should take back Visa applications from the Australian Visa Agents & process them. Visas should be a Fed Govt jurisdiction not some money-hungry, treasonous private agents.
So far as Chinese business & any other nationality is concerned, Australia should adopt a strategy of no Australian run business in those countries then no business from them in this country ! Full Stop !
Stop exporting so much ore etc, process here & then export the refined product. I mean how much more idiocy can we afford to tolerate from our bureaudroids ?

individual,

You saying they've been here on temporary visas for the past 70 years?

Good, even more reason to piss them off to China.

One of the attitudes that seems to get applied to Chinese overseas by
the Chinese government is that your ancestral country requires you to
support the CCP and government.
It is an echo of the Central Kingdom.
Just what percentage of Chinese immigrants or even those born here
respond to the blandsishments is hard to say but it is a factor as
recent prosecutions in the US and the publicity about the 1000 Talents scandal indicates.
