Peppermint Grove Property Investor Report
Why this suburb, why now, and what could go wrong: prices vs Perth, yields, vacancy, the supply pipeline, demographics, infrastructure and a clear strategy verdict for Peppermint Grove (6011).
Data compiled 2026. Every figure is attributed to a named source below.
The short version
Peppermint Grove is the smallest local government area in Australia and one of the wealthiest, a tiny riverfront enclave on Freshwater Bay wedged between Cottesloe and Mosman Park. It is the rarest address in Perth: barely 600 dwellings, a median house price around $6.5 million, and fewer than 30 sales in a typical year. You are not buying a market here, you are buying a postcode.
With sales that thin, the published numbers are extremely volatile and the median is close to meaningless on any single deal. Yields sit near 2%, there is almost no apartment stock, and development is effectively frozen by the Shire's tiny footprint. This is the purest scarcity and capital-preservation play in the city, and one of the least liquid.

1. Suburb snapshot
Peppermint Grove is a tiny riverfront enclave about 12km west of the Perth CBD, sitting on the north bank of the Swan River at Freshwater Bay, between Cottesloe and Mosman Park. It is the smallest local government area in Australia, covering roughly one square kilometre with only around 600 dwellings, and one of the highest-income communities in the country. For investors that produces an extreme version of the prestige profile: maximum scarcity, almost no transactions, very low yields and essentially no new supply. The thesis here is the address itself, a riverfront postcode that is effectively impossible to expand.
2. Sales and price trends
The Peppermint Grove median house price sits in a wide band around $6.4 to $6.65 million: Your Investment Property and PropertyValue show about $6.4 million, property.com.au about $6.65 million, and REIWA about $6.5 million (Your Investment Property; property.com.au; REIWA). With fewer than 30 sales a year, those figures swing heavily from one period to the next, so the median is best read as a broad indication of the price band, not a precise market level. There is no reliable published unit median, because the suburb is almost entirely houses.
Published annual growth figures range from about 47% to 66% (Your Investment Property; REIWA), but those numbers are the product of a tiny sample and the mix of which trophy homes happened to sell, not a repeatable trend. For comparison, Perth's median house price rose roughly 18% over the past year to about $1.09 million (Domain via ABC News), so Peppermint Grove's median is roughly six times the metro figure.
With this few sales, every published median and growth figure is volatile by nature.
"Peppermint Grove is the one suburb where I tell clients to ignore the statistics almost entirely. When fewer than thirty homes sell in a year, a 50% jump in the median just means a couple of big riverfront places traded that year. You can't trade this suburb and you can't time it. What you can do is buy the right block when it appears and hold it for a generation. The value here is the scarcity of the address and the Freshwater Bay frontage, and that doesn't move with the weekly market the way a normal suburb does."
3. Rental market and yield
Houses rent for roughly $1,850 to $1,950 a week, very high in absolute dollars (Your Investment Property; RealEstateInvestar), but against a median around $6.5 million that is a gross yield of only about 2.0% to 2.7%. As in the other trophy suburbs, the rent comes nowhere near covering the cost of holding the asset, so a Peppermint Grove purchase only makes sense on capital preservation and land value over a very long hold.
The unit market is too small to offer a real income alternative; only a handful of units exist and sell. This is a house, and more precisely a land-and-address, market, and the income trade-off is simply part of owning here.
Even at nearly $2,000 a week in rent, a Peppermint Grove house yields about 2% gross. This is a capital-preservation asset, not an income one.
4. Supply and demand indicators
The defining feature of Peppermint Grove is how rarely anything changes hands. Only around 26 to 30 houses and a handful of units sold in the past year (Your Investment Property; PropertyValue), and about 20.5% of homes are rented (ABS 2021 Census). A reliable suburb-level vacancy rate is not separately published given how few rentals there are, but the combination of minimal turnover and a small rental pool is the signature of an enclave that almost never trades.
On supply, there is effectively none. The Shire of Peppermint Grove is one square kilometre of established homes with no room and little appetite for new development, so there is no apartment pipeline and no meaningful capacity to add dwellings. For an owner, that is the entire point: the scarcity is permanent in a way no zoning change can easily undo.
"There is nowhere for Peppermint Grove to grow. It's a one-square-kilometre shire that's already built out, so unlike almost anywhere else in Perth, you don't have to worry about a tower going up next door or a new estate diluting the area. That permanence is what high-net-worth buyers are really paying for. The flip side is patience: stock is so rare that you can wait a year or two for the right home, and when it comes, you compete hard. This is a buy-and-hold-forever suburb, not a portfolio you trade."
5. Demographics and affordability
Peppermint Grove is one of the highest-income, most family-oriented and most owner-occupied communities in Australia. The 2021 Census recorded a population of about 1,597, little changed since 2016, a median age of 42, and a median household income near $4,565 a week, well over double the Greater Perth figure (ABS 2021 Census). About 77% of households are families, around 20.5% rent, and 50.3% own their home outright. This is a settled, high-equity enclave whose residents rarely need to sell.
6. Infrastructure and growth drivers
The demand investors are really buying into comes from Peppermint Grove's river position, schools and rarity:
- Freshwater Bay and Keane's Point. Peppermint Grove sits on the Swan River at Freshwater Bay, with the Keane's Point reserve and foreshore giving the enclave a scarce, built-out riverfront, the heart of the address.
- CBD access. Peppermint Grove is about 12km from the Perth CBD; it is serviced by nearby Cottesloe station on the Fremantle line and local bus routes, giving rail and road access to the city without a station in the enclave itself.
- Schools. Presbyterian Ladies' College sits within Peppermint Grove, and the suburb is surrounded by the western-suburbs private schools (Iona at Mosman Park, MLC and Christ Church at Claremont), a defining feature of the area's appeal to families.
- Cottesloe and the coast. Peppermint Grove is minutes from Cottesloe Beach and the Claremont retail precinct, combining riverfront living with quick access to the coast and town-centre amenity.
- Permanent scarcity. A one-square-kilometre, fully built-out shire means the supply of homes here is effectively fixed, the core of the long-run value case (see section 4).
7. Risk assessment and strategy fit
- Extreme illiquidity. Fewer than 30 sales a year makes both buying and selling slow and competitive; this is among the least liquid markets in Perth.
- Very noisy data. With such a small sample, medians and growth rates swing wildly and tell you little about any specific property; only genuine local evidence can value a home here.
- Very low yield. Yields near 2% mean large annual holding costs; the case rests entirely on land, address and long-run capital preservation.
- Capital concentration. Entry at $5 to $7 million-plus concentrates a very large amount of capital in one illiquid asset, suitable only for a specific high-net-worth investor.
- No income alternative. There is effectively no apartment market, so there is no higher-yielding way into the postcode.
Strategy fit. Peppermint Grove suits a high-net-worth, low-gearing buyer who wants the rarest riverfront address in Perth for long-term capital preservation and is content to hold for a generation through a near-zero-yield, very illiquid market. It does not suit a geared, income-focused or liquidity-sensitive investor in any way.
8. The investor verdict
Put the pieces together and Peppermint Grove is the purest scarcity asset in Perth: the smallest, wealthiest shire in the country, a riverfront enclave on Freshwater Bay where fewer than 30 homes trade a year, the median is close to meaningless, supply is permanently fixed and yields are minimal. You buy here for the address, the riverfront and the certainty that it can never be diluted, and you hold it for the very long term. Treat the published figures as volatile signals, value the specific block and its outlook, be patient for the right home, and let comparable-sales evidence and negotiation, not the asking price, decide what you pay.
