Recent residential development output has been above average within Shellharbour when compared nationally

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Shellharbour has experienced around 38 dwellings receiving development approval annually. An estimated 192 homes have been approved over the past five financial years, between FY-21 and FY-25, with a further 25 approved so far in FY-26. On average, 1.9 people per year moved to the area for each dwelling built during this period, indicating balanced supply and demand conditions.

The average expected construction cost of new homes over these years was $603,000, suggesting developers focused on the premium market with high-end developments. In FY-26, commercial development approvals totalled $4.9 million, showing limited focus on commercial development compared to residential. Compared to the rest of NSW, Shellharbour exhibited moderately higher construction activity, at 18.0% above the regional average per person over the five-year period. This has preserved reasonable buyer options while sustaining existing property demand. New developments in Shellharbour consisted of 24.0% detached houses and 76.0% medium to high-density housing between FY-21 and FY-25, reflecting a shift towards denser development to cater to downsizers, investors, and entry-level buyers.

This change contrasts with the current housing mix, which is predominantly houses at 69.0%. This trend may be due to reduced availability of development sites and shifting lifestyle demands. Shellharbour's population growth is expected to add 2,181 residents by 2041, based on the latest AreaSearch quarterly estimate. If current construction levels persist, housing supply could lag behind population growth, potentially intensifying buyer competition and supporting price growth.
