What is the Area of Brisbane city?

Question

I am after the size of Brisbane city. Most online sources I can find say around 6 000 square kilometers, but if you do just basic measurements on a map, it looks like this is the size of Greater Brisbane. I am after just Brisbane, excluding Logan and Ipswich cities.

Answer 1

Population : 1,857,594 (2007)

Density : 918/km² (2377.6/sq mi) (2006)

Area : 5904.8 km² (2279.9 sq mi)

Answer 2

Population density is 379.4 people per square km.

Population is 1,763,131 (2006 census).

1,763,131 / 379.4 = 4,647.15604 km^2
