New Zealand was never a state of Australia. New Zealand was briefly (for one year: 1840) a dependency of the colony of New South Wales in Australia, but this was before either New Zealand or Australia were regarded as separate nations. The Commonwealth of Australia was established in 1901. New Zealand declined to become a member, and became a British Dominion in 1907.
No records exist regarding when Australia was first "discovered" by its indigenous people, whilst records concerning the Polynesians and Maori of New Zealand are not necessarily based on fact. It is likely, however, that Aborigines were in Australia long before any races were on New Zealand. Regarding discovery by Europeans explorers, to our knowledge, the Australian continent was discovered by Europeans, specifically Portuguese explorers, before New Zealand.
