Can Australian-born children get a permanent residence visa in Australia?

If an Australian adopts a child from overseas, can he become an Australian citizen? If the applicant finds out that she is pregnant after submitting her immigration application, will this affect her immigration application? I believe all of us may encounter these problems, so I will make a brief statement on them here. Unlike the United States or Hong Kong, Australia naturally becomes a citizen of the local country as long as a pregnant woman gives birth to a child. In Australia, a newborn will become an Australian citizen only if its parents are Australian citizens or permanently live in Australia; Otherwise, any child born in Australia can only get the same visa as when his parents were born. As for children adopted overseas by Australian citizens, it is not natural to get an Australian visa. In fact, the problem of adopting children is quite complicated to operate. The key is whether your adoption procedure conforms to The Hague Convention on International Adoption. In other words, if you don't have a set of legal procedures when adopting a child, then Australia can't legally recognize your right to adopt a child, and the child can't solve the problem of Australian identity. Of course, there is still a solution to the visa problem without legally adopted children. One of the solutions is that if the Australian adopter has lived with the child for more than two years and has formed a de facto adoption relationship, then the child still has the hope of obtaining an Australian visa. If the applicant finds out that he is pregnant after submitting the immigration application, it is worthy of congratulations and will also add a little trouble to the applicant. If the applicant fails to complete the immigration medical examination, the immigration application will be stopped or rejected because the medical examination cannot be completed. If the applicant's child was born after the immigration visa was approved, you need to submit a new immigration application for the newborn separately. It should be reminded that if the child is born while the applicant is waiting for the trial, the applicant can put the newborn as an affiliated applicant in the immigration application. Therefore, once the applicant finds out that she is pregnant, please plan carefully to avoid more trouble.
