Weren’t you the same member who made a
ridiculous unsubstantiated claim that the Sydney to Shanghai route was a national security risk earlier in this thread? Do you think all Australians only travel to the US, UK, EU, Canada, Japan and New Zealand and nowhere else?
Moral-based factors like what you have listed above have not much to do with decisions made by Australians in regards to travel. The countries where the ME3 are based are known for their horrible treatment of specific groups based on religion, sexuality, ethnicity and employment factors (and I think most travelling Australians are aware of that) - yet that doesn’t deter Australians from flying on their state owned airlines and visiting those countries. And it shouldn’t be a deterring factor. I think the same would apply to China (although China is much more of a destination than transit - although same idea applies). If there’s no visa requirement and prices are competitive, then there’ll almost certainly be a surge in leisure, family and business demand between Australia and China, from the Australian side.
