This is NEVER going to happen. Australia is a developed economy, not some developing country in Africa, that mean we can choose who to invest and who to prosper, and it's in Australian government proposition that Australian economy will NOT BE DOMINATED BY A FOREIGN PARTY. Be it US or China.
You like to invest, that's your call, but in the end, it's ALWAYS GOING TO BE AUSTRALIAN First, it's basically in your dream that you can dominate Australia.
People don't know anything and got exciting by minimum of excitement. They weren't thinking straight or not even thought about it at all, then what do you expect??
