AreaSearch assessment of residential development drivers sees a low level of activity in Miller, placing the area among the bottom 25% of areas assessed nationally

AreaSearch analysis of ABS building approval numbers indicates around 13 new homes approved annually in Miller over the past five financial years. This totals an estimated 68 homes. In FY26 so far, 11 approvals have been recorded.

The population has declined recently, suggesting that new supply has likely met demand, providing good choice for buyers. New homes are being built at an average value of $222,000, below the regional average, offering more affordable housing options. Compared to Greater Sydney, Miller has significantly less development activity, 80.0% below the regional average per person. This limited new supply generally supports stronger demand and values for established homes.

New building activity shows 73.0% standalone homes and 27.0% medium and high-density housing, preserving the area's suburban nature with an emphasis on detached housing attracting space-seeking buyers. Miller reflects a low density area, with around 285 people per approval. According to AreaSearch's latest quarterly estimate, Miller is expected to grow by 650 residents through to 2041. Construction maintains a reasonable pace with projected growth, although buyers may face growing competition as population increases.
