Overseas migration contributed approximately 82.0% of overall population gains during recent periods in the suburb.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data, AreaSearch utilises NSW State Government's SA2 level projections released in 2022 with a base year of 2021. Growth rates by age group from these aggregations are applied to all areas for years 2032 to 2041. Considering projected demographic shifts, the suburb is forecasted to experience significant population growth, expanding by 1,544 persons to reach approximately 8,009 people by 2041, reflecting an increase of 18.9% in total over the 17 years.

Residential development activity is lower than average in Dundas Valley according to AreaSearch's national comparison of local real estate markets

AreaSearch analysis based on ABS building approval numbers shows Dundas Valley had approximately 42 dwelling approvals annually over the past five financial years ending FY26. This totals around 211 homes. By May 2026, 38 approvals were recorded. Population decline has not led to housing supply shortages, maintaining a balanced market with varied buyer choices.

Average new property construction value is $639,000, indicating premium market targeting. In FY26, $2.1 million in commercial development approvals were recorded, suggesting minimal commercial activity. Compared to Greater Sydney, Dundas Valley records about 68% of building activity per person and ranks at the 66th percentile nationally. New building activity comprises 25.0% detached houses and 75.0% medium-high density housing, appealing to downsizers, investors, and entry-level buyers. This shift reflects decreasing developable sites and changing lifestyles.

With around 209 people per dwelling approval, Dundas Valley exhibits growth area characteristics. AreaSearch's latest quarterly estimate projects population growth of 1,215 residents by 2041. Current development rates should comfortably meet demand, offering good buying conditions and potentially supporting growth beyond current projections.
