Peppermint Grove

An assessment of population growth drivers in Peppermint Grove reveals an overall ranking slightly below national averages considering recent, and medium term trends

Based on analysis of ABS population updates for the broader area, as of Nov 2025 the suburb of Peppermint Grove's population is estimated at around 1,873. This reflects an increase of 276 people since the 2021 Census, which reported a population of 1,597 people. The change is inferred from the resident population of 1,868, estimated by AreaSearch following examination of the latest ERP data release by the ABS (June 2024) and an additional 1 validated new address since the Census date. This level of population equates to a density ratio of 1,750 persons per square kilometer, which is above the average seen across national locations assessed by AreaSearch. Peppermint Grove's growth of 17.3% since the 2021 census exceeded the national average (8.9%). Population growth for the area was primarily driven by overseas migration that contributed approximately 90.0% of overall population gains during recent periods.

AreaSearch is adopting ABS/Geoscience Australia projections for each SA2 area, as released in 2024 with 2022 as the base year. For areas not covered by this data, and to estimate growth post-2032, AreaSearch utilises growth rates by age cohort provided by the ABS in its latest Greater Capital Region projections (released in 2023, based on 2022 data). Considering these projections, an above median population growth is projected for the suburb with an expected expansion of 345 persons to 2041, reflecting a gain of 14.6% in total over the 17 years.

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

AreaSearch analysis of ABS building approval numbers, allocated from statistical area data, indicates Peppermint Grove has seen approximately 8 new homes approved annually. Over the past 5 financial years, between FY-21 and FY-25, around 43 homes were approved, with an additional 2 approved so far in FY-26.

This results in an average of about 4 new residents per year for every home built during these years. Consequently, demand significantly outpaces supply, typically exerting upward pressure on prices and increasing competition among buyers. New properties are constructed at an average expected cost value of $1,189,000, indicating a focus on the premium segment with upmarket properties. Comparatively, Peppermint Grove has similar development levels per person relative to Greater Perth, maintaining market balance consistent with the broader area. However, development activity has increased in recent periods.

The new development consists of 36.0% detached dwellings and 64.0% townhouses or apartments, marking a significant shift from existing housing patterns which are currently 78.0% houses. This skew towards compact living offers affordable entry pathways, attracting downsizers, investors, and first-time purchasers. With around 154 people per dwelling approval, Peppermint Grove exhibits characteristics of a growth area. According to the latest AreaSearch quarterly estimate, Peppermint Grove is projected to add approximately 273 residents by 2041. Given current construction levels, housing supply should adequately meet demand, creating favourable conditions for buyers while potentially enabling growth that exceeds current forecasts.
