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, the SA State Government's Regional/LGA projections by age category are adopted, based on 2021 data and released in 2023. These projections have been adjusted using 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 Myrtle Bank (SA) area. Based on aggregated SA2-level projections, the area is expected to grow by 611 persons to reach a total population of approximately 4,033 people by 2041, reflecting a 17-year increase of 18%.

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

AreaSearch analysis of ABS building approval numbers from statistical area data shows Myrtle Bank had approximately 10 dwellings receiving development approval per year. Between financial years FY-21 and FY-25, around 51 homes were approved, with another 8 approved in FY-26 so far. Each dwelling built over these five years resulted in an average of 2.3 new residents per year, indicating strong demand supporting property values.

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

New building activity comprises 58.0% standalone homes and 42.0% attached dwellings, offering a range of medium-density options across different price brackets. Currently, Myrtle Bank reflects around 273 people per approval. AreaSearch's latest quarterly estimate forecasts the area to gain approximately 488 residents by 2041. If current construction levels persist, housing supply may lag population growth, potentially intensifying buyer competition and underpinning price growth.
