Can Australian pr go directly to the United States?

If you only get PR, you can only enter Australia and New Zealand without a visa. All other countries need a visa, because you are still a citizen of China. But once you are naturalized, you become an Australian citizen.

If one parent is an Australian green card holder, if the child is born in Australia, then the child is an Australian citizen at birth. If the child is born in China, then the child is a citizen of China, and of course he can apply for an Australian green card in the future. If one parent is an Australian citizen, no matter where the child was born (such as China), the child is born an Australian citizen.

PR among immigrants refers to the permanent residence visa/right in Australia, valid for 5 years. If you have lived for two years within five years, you can apply for naturalization or continue to renew your PT visa.
