Did you immigrate to Australia to become Australia? Is your nationality Australia?

Immigrating to Australia is not necessarily an Australian citizen. Immigration to Australia can have three different States: temporary visa, Australian green card (permanent residence visa) and naturalized Australian citizen, so it cannot be said that immigration to Australia is an Australian citizen.

According to Australia's policy, the first thing you get is a temporary residence visa (such as Australia 188A visa). After further meeting certain conditions, you can apply for a permanent residence visa, and then meet other conditions, apply for Australian citizenship, become an Australian citizen and obtain an Australian passport.
