Port Kennedy, WA 6172
City Of Rockingham, Western Australia
Good to Know
Port Kennedy, WA 6172 is a high-value house market in the City Of Rockingham area, currently positioned as a short-cycle capital growth submarket. Located about 50 km south of Perth CBD, Port Kennedy is home to roughly 13,477 adults across 5,851 dwellings, with a current vacancy rate of 0.76%.
According to HtAG Analytics, Port Kennedy is exhibiting tight demand with constrained listings even as approvals run high. Stock on Market sits at 0.29% and Inventory at 3.21 months — just above the ~3-month balanced-market threshold — driving +17.2% YoY price growth and +2.6% YoY rent growth.
What the market data is signalling
Port Kennedy is showing classic capital-growth dominance: prices have surged 17.2% over the past year while rents have only moved +2.6%, pointing to demand-led appreciation rather than yield compression. Low listed supply — Stock on Market is just 0.29% and vacancy is an opportune 0.76% — has amplified price momentum, even though the indicative gross yield sits at a reasonable 3.34%.

Who lives in Port Kennedy — and why it matters for investors
Port Kennedy records an IRSAD decile of 4, indicating a lower‑affluence demographic profile that can increase sensitivity to economic shocks and rental demand swings. The renter/owner split is 22%, which is in the neutral band and suggests a balanced mix of owner-occupiers and renters — a structural feature that can moderate short-term volatility.

Why suburb-level data matters for Port Kennedy

What's behind the RCS™ score of 71
The HtAG RCS™ (Rating Composite Score) of 71 blends three independent dimensions — risk minimisation, capital-growth potential and cashflow resilience — into one composite measure. Inspecting the sub-scores helps match Port Kennedy to an investor’s strategy: the current profile favours capital growth but requires attention to cashflow margins and supply signals.

Forward signals to watch
vacancy rate — currently 0.76%: sustained sub‑1% vacancy usually supports stronger rent and price resilience over 12–24 months; tightening can also compress tenant choice and push rents up if supply stays limited.
building approvals ratio — currently 3.35%: this elevated approvals reading is unfavourable from a supply-risk perspective and may add new listings in the medium term, which could ease price momentum if projects complete in volume.
Perth cycle phase: a shift in the Perth metro cycle (for example from expansion to peak or contraction) would alter local pricing dynamics and rental demand, so track city‑level momentum alongside Port Kennedy’s suburb metrics.

Area Risks
Property data alone won't flag the structural risks that can erode a long-hold position. Bushfire overlays, flood-zone exposure, and economic concentration sit outside the price feed but determine whether your capital is insurable, defensible, and structurally protected. Unlock to see.
Are there hidden structural risks shaping Port Kennedy's long-hold story?
Beyond the headline price, Port Kennedy carries risk signals a median can't show — hazard exposure from bushfire and flood overlays, and how narrowly local employment leans on a handful of sectors (the concentration the EDI score quantifies). Together these separate insurable, defensible long-holds from those carrying tail-risk that never surfaces in the headline number.

Supply & Demand
Port Kennedy's headline numbers show where the market is today. The two cards below answer where it's heading. Direction is what separates a buy from a wait.
Is housing supply tightening or building up?
Stock on Market is one number — the trend is what matters. SoM, inventory, building approvals and hold period together reveal whether the market is starving for stock (price pressure up) or quietly building a pipeline (pressure down).

Is buyer and renter demand heating up or cooling off?
Vacancy is one signal — the real question is whether demand is still building or quietly peaking. Days on market, vacancy, search index and clearance rate are the four pulse-points — when they diverge, they signal a turning point.

Port Kennedy can look solid on the surface — but the three layers below separate markets that genuinely hold value from ones that only look like they do.
Is Port Kennedy genuinely stable - or just expensive?
IRSAD hints at affluence, but socio-economic strength alone doesn't guarantee resilience. Combined with the renter-to-owner balance and unit-to-house ratio, you get the three signals that separate a tightly-held submarket from one carrying hidden volatility.
