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

Gagebrook has recorded approximately one residential property approval per year over the past five financial years, totalling eight homes. No residential approvals have been recorded so far in FY26. This results in an average of 12.9 new residents per home built annually between FY21 and FY25, indicating significant demand outstripping supply. Commercial development approvals this year amount to $638,000, reflecting a predominantly residential focus.

Compared to Greater Hobart, Gagebrook has notably lower building activity, with 89.0% below the regional average per person.

With approximately 3216 people per approval, Gagebrook exhibits characteristics of a mature, established area. Future projections estimate an addition of 287 residents by 2041, suggesting potential challenges in housing supply keeping pace with population growth under current development rates.

Future projections show Gagebrook adding 287 residents by 2041 (from the latest AreaSearch quarterly estimate). At current development rates, housing supply may struggle to match population growth, potentially heightening buyer competition and supporting price increases.
