interesting

There are approximately 4.5 million people living in Sydney Metropolitan area (700 Square miles). Interesting that there is 4.5 million people in the entire STATE of Queensland (look at map, its huge with about 667,000 square miles). Of that 4.5 million....about 2 million (2/3rds) live in Brisbane City (817 square miles). Therefore the additional 666,200 square miles holds the other 2.5 million). It is estimated that approximately 16,000 people move to Brisbane per year.

For perspective...
There are nearly...
8 million people in New York
4 million people in Los Angeles
3 million people in Chicago
333200 people in Cincinnati city limits (76.9 Square miles)
900K in Hamilton County (413 square miles)

So Brisbane is nearly 7X larger than Cincinnati...
