This reflected an increase of 1,583 people (12.2%) since the 2021 Census, which reported a population of 12,985 people.

AreaSearch adopted ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For any SA2 areas not covered by this data, and to estimate growth across all areas in the years post-2032, AreaSearch utilised the growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Moving forward with demographic trends, a population increase just below the median of national statistical areas was expected. The area was expected to grow by 1,104 persons to 2041 based on the latest population numbers, recording a gain of 7.5% in total over the 17 years.
