Sixteen Adelaide suburbs carried a $2 million-plus median house price in February 2026 when the Reserve Bank first lifted rates this cycle. By August that count had cycled through 22, 21 and 20, and even after two further hikes it still sat at 20 — a pattern realestate.com.au reports has held through nine months of rising rates. Kensington Gardens, meanwhile, has added $485,056 to its median in a single year, a 28.9% jump that puts the suburb at $2.165m.
The $2m Suburb Count That Refuses to Fall
The resilience of Adelaide's prestige tier is not a one-month blip. Analysis of realestate.com.au data tracked the number of $2m-median suburbs at every RBA meeting since February: 16, then 18 and 20 across March and May, 19 in April when the board held, then 22, 21 and 20 through the June-to-August hold period. When rates rose again over the following two months, the count sat at 22 and 20 — effectively unchanged from where it started.

Williams Real Estate principal Stephanie Williams points to rarity rather than rate settings as the driver. She describes a recent Unley Park sale that cleared in three days and singles out Tennyson as one of the strongest pockets in the state right now, arguing that buyers at this bracket are largely insulated from mortgage-rate movements because the properties themselves rarely come to market. That scarcity dynamic is the mechanism by which a handful of blue-chip addresses can keep setting new benchmarks while the rest of the state corrects.
Five Suburbs, $300k-Plus in Annual Gains
A second data pull from realestate.com.au sharpens the picture at suburb level. Kensington Gardens leads on dollar growth, up $485,056 (28.9%) to $2.165m. Payneham follows with the largest percentage gain of the group — $421,000, or 43.2%, taking its median to $1.396m. St Peters added $415,000 (19.8%) to reach $2.515m, West Beach gained $344,000 (24.2%) to hit $1.764m, and Kensington Park rose $330,000 (19.6%) to $2.010m.
REISA chief executive Andrea Heading frames these pockets as tightly held and dominated by larger blocks — a different asset class to the volume-driven lower end of the market. Her read is that the top end is absorbing the downturn better than entry-level stock, and that peak selling season should bring more of these rare listings forward rather than trigger price cuts.
Adelaide's $2m-plus suburb count has ranged between 20 and 22 since June even as the RBA's cash rate pushed higher, while the city's overall median dwelling value fell 3.4% from its May peak and dropped $8,000 in the most recent month alone.
The Other Adelaide: A Market Falling for a Fifth Month
The prestige-tier story sits against a much softer citywide backdrop. Adelaide's median home value dropped 0.6%, or $8,000, in the most recent month on realestate.com.au's Home Price Index — the fifth consecutive monthly decline and the largest fall of any capital for a second straight month. Homeowners have lost $44,000 off house values over five months, and the city's median dwelling value is now down 3.4% from its May peak, even though it still sits above $900,000.
Senior economist Eleanor Creagh describes the shift as striking given how recently Adelaide ranked among the country's strongest markets. Her view is that five years of growth exceeding 60% eroded the affordability buffer that once made Adelaide relatively cheap, and that higher mortgage rates are now constraining what buyers at the median can borrow far more than they constrain buyers at the $2m-plus end, where equity and cash positions dominate purchasing power.
Adelaide's Split Against the National Picture
South Australia's two-speed pattern mirrors a broader national divergence showing up in REAStats tracking. Nedlands in Western Australia posted 15% annual growth against a 15-day median selling cycle, while Dandenong in Victoria managed just 2.3% growth over a 40-day cycle — evidence that the gap between tightly-held, high-demand pockets and broader metro stock is not unique to South Australia. The national auction clearance rate sits at 68.8%, with Sydney at 70.8% and Melbourne at 68.8%, underscoring that even in a market recording falls for a fifth or sixth straight month nationally, clearance strength is concentrating in specific suburb tiers rather than spreading evenly.
Reading suburb-level clearance and growth figures in isolation can be misleading without understanding how national benchmarks are built — our guide to auction clearance rates explains why a 20-point gap between prestige and outer-metro suburbs is common even within a single capital city. Similarly, the Kensington Gardens and Payneham figures cited above are median prices rather than averages, a distinction covered in median vs average pricing, which matters because a handful of exceptional sales can distort averages in thin, tightly-held markets far more than they distort medians.
Further Reading: Rental Supply as a Downstream Signal
Prestige-tier resilience and broader price falls both have knock-on effects for rental supply, since owner-occupiers in blue-chip suburbs rarely release stock regardless of rate settings while softer entry-level markets can see more churn. Our explainer on rental vacancy rates sets out how these supply dynamics interact with price corrections over a 12-to-18-month horizon.
For agents working Adelaide's top end, the data supports continuing to prioritise off-market pipelines in suburbs like Tennyson and Unley Park over broad-based campaign marketing, since REISA's own commentary points to scarcity — not price discovery — as the dominant factor. For buyers priced below the $1.5m mark, the fifth consecutive monthly decline and $44,000 five-month value loss suggest further near-term softening is more likely than a rebound, while vendors in $2m-plus suburbs retain unusual pricing power heading into peak season. The gap between these two Adelaides is unlikely to close quickly; if anything, Stephanie Williams's expectation of further prestige supply tightening suggests the $300k-plus annual gains in Kensington Gardens, Payneham and St Peters could extend into next year even as the broader market continues correcting.
