AUSTRALIAN POPULATION GRID 2017
FIGURE 1. ESTIMATED RESIDENT POPULATION DENSITY GRID, June 2017
Australia's most densely populated area in 2017 was in Melbourne near Carlton. The 1 km2 grid cell covering these localities had an estimated residential population of 25,743.
Figure 2 compares the population grid for Sydney and Melbourne. It shows that Sydney had more areas in the highest density range shown in the map with 48 km2 exceeding 8,000 people per square kilometre compared to Melbourne which only had 14 km2 exceeding 8,000 people per square kilometre. Sydney also had larger and more widely spread areas of the second highest density class with 126 km2 of between 5,000 and 8,000 people per square kilometre, while Melbourne had 51 km2 in the same range. Brisbane was the only other capital city to register in these higher density categories with 9 km2 between 5,000 and 8,000 people per square kilometre.

Table 1 shows the area within each Greater Capital City Statistical Area (GCCSA) under 6 population density classes, from no population to very high. These areas are calculated from the Population Grid and the classes are based on the ranges used in Figures 1 and 2. The Brisbane GCCSA had the largest area of very low population density (less than 500 people per square kilometre) at 9,557 km˛ in 2017. This highlights the spread of low density population around Brisbane and also the relatively large extent of the Brisbane GCCSA when compared with other capital cities.
