I want to know the answer to the following question:
What is the second most populas city in Australia?
All the background I'm provided with is that "Melbourne (/ˈmɛlbərn/, AU i/ˈmɛlbən/) is the capital and most populous city in the Australian state of Victoria, and the second most populous city in Australia and Oceania.". Is that enough to answer the question?
Answer: yes
