AreaSearch assessment of residential development activity positions Melonba among the top 25% of areas assessed nationwide

Melonba has seen approximately 526 new homes approved annually based on AreaSearch analysis of ABS building approval numbers. Over the past five financial years, from FY-21 to FY-25, around 2,632 homes were approved, with an additional 125 approved so far in FY-26. On average, each dwelling constructed has resulted in approximately 0.7 new residents over these five years, indicating that new supply is meeting or exceeding demand and providing ample buyer choice while creating capacity for population growth beyond current forecasts.

The average construction cost value of new homes is around $483,000, suggesting a focus on the premium segment with upmarket properties. In FY-26, commercial development approvals have totalled $995,000, indicating minimal commercial development activity in Melonba compared to Greater Sydney. Relative to Greater Sydney, Melonba shows 2315.0% higher development activity per person, offering buyers greater choice and suggesting strong developer confidence in the location. However, development activity has moderated in recent periods. New building activity in Melonba consists of approximately 81.0% detached dwellings and 19.0% townhouses or apartments, preserving the area's suburban nature while also providing more diverse housing options. This shift represents a notable change from the area's existing housing composition, which is currently 99.0% houses, indicating decreasing availability of developable sites and reflecting changing lifestyles.

The location has approximately 7 people per dwelling approval, suggesting an expanding market. Future projections estimate Melonba to add around 17,896 residents by 2041 based on the latest AreaSearch quarterly estimate. Given current development patterns, new housing supply should readily meet demand, offering good conditions for buyers and potentially facilitating population growth beyond current projections.
