Fastest growing Local Government Areas
There are well over 500 Local Government Areas (LGAs) in Australia. Six of the ten fastest growing LGAs last year were in Victoria while the fastest growing LGA is Camden, in New South Wales. Western Australia and Queensland only have one LGA in the top ten.
Population Size and Area Differences
Australia’s LGAs are not all the same size. In terms of area, Western Australia is home to both the biggest LGA (East Pilbara at 372,307 km2) and the smallest LGA (Peppermint Grove at just over one km2).
In terms of population, the largest LGA is Brisbane (Qld) at over 1.2 million people. The smallest is Maralinga Tjarutja (SA) with 64 people.
This means the growth in the number of people, as well as the growth rate, is important to consider in comparisons across LGAs.
Drivers of growth
Not only do LGAs differ in the speed at which they grow, they also differ in how they grow. The four fastest growing LGAs are driven mostly by net internal migration, people already in Australia moving there from elsewhere.
Melbourne city is driven by net overseas migration, while existing residents are leaving.
Natural increase isn’t the biggest driver for any of the top ten.
