AreaSearch adopts ABS/Geoscience Australia projections for each SA2 area, released in 2024 with a base year of 2022. For areas not covered by this data and years post-2032, SA State Government's Regional/LGA projections are adopted with adjustments made employing a method of weighted aggregation of population growth from LGA to SA2 levels. Considering projected demographic shifts, an above median population growth is projected for the area, with an expected increase of 606 persons by 2041 based on aggregated SA2-level projections, reflecting a total increase of 14.1% over the 17-year period.

AreaSearch analysis of residential development drivers sees Myrtle Bank recording a relatively average level of approval activity when compared to local markets analysed countrywide

Based on AreaSearch analysis of ABS building approval numbers allocated from statistical area data, Myrtle Bank has experienced around 10 dwellings receiving development approval per year. Approximately 51 homes were approved over the past five financial years, between FY-21 and FY-25, with another 8 approved so far in FY-26. Each dwelling built, on average, has gained 2.3 new residents annually over these five years, indicating solid demand that supports property values.

New homes are being constructed at an average expected cost of $879,000, reflecting a developer focus on the premium segment with upmarket properties. This year alone, $6.1 million in commercial development approvals have been recorded, suggesting the area's residential character. When compared to Greater Adelaide, Myrtle Bank maintains similar construction rates per person, supporting market stability aligned with regional patterns. However, this activity is below average nationally, reflecting the area's maturity and possible planning constraints.

New building activity comprises 58.0% standalone homes and 42.0% attached dwellings, offering a mix of medium-density options across various price brackets. Currently, there are around 273 people per approval in Myrtle Bank, indicating a transitioning market. According to the latest AreaSearch quarterly estimate, Myrtle Bank is forecasted to gain approximately 483 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and underpinning price growth.
