AreaSearch is adopting 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, AreaSearch is utilising the NSW State Government's SA2 level projections, as released in 2022 with 2021 as the base year. Growth rates by age group from these aggregations are also applied to all areas for years 2032 to 2041. Moving forward with demographic trends, lower quartile growth of national statistical areas is anticipated, with the area expected to expand by 149 persons to 2041 based on the latest annual ERP population numbers, reflecting a decrease of 0.1% in total over the 17 years.

AreaSearch assessment of residential development drivers sees a low level of activity in Lake Munmorah - Mannering Park, placing the area among the bottom 25% of areas assessed nationally

Lake Munmorah - Mannering Park has recorded around 15 residential properties granted approval each year, totalling 78 homes over the past 5 financial years. So far in FY-26, 17 approvals have been recorded. With an average of only 0.5 people per year moving to the area for each dwelling built over the past 5 financial years (between FY-21 and FY-25), new construction is matching or outpacing demand, offering buyers more options and enabling population growth that could exceed current expectations, while new properties are constructed at an average value of $251,000—below the regional average—suggesting more affordable housing options for buyers. There have also been $690,000 in commercial approvals this financial year, indicating minimal commercial development activity.

Compared to Greater Sydney, Lake Munmorah - Mannering Park shows substantially reduced construction (67.0% below regional average per person). This limited new supply generally supports stronger demand and values for established properties. This activity is similarly under the national average, indicating the area's established nature and suggesting potential planning limitations. New building activity shows 83.0% detached houses and 17.0% townhouses or apartments, maintaining the area's traditional low density character with a focus on family homes appealing to those seeking space. The estimated count of 1268 people in the area per dwelling approval reflects its quiet, low activity development environment.

With population projections showing stability or decline, Lake Munmorah - Mannering Park should see reduced housing demand pressures, benefiting potential buyers.
