Reading demand-to-supply ratios honestly
What the metric actually shows, where it lies, and the secondary inputs we cross-check before any shortlist.
The demand-to-supply ratio (DSR) is the most over-quoted number in Australian property research. It’s also the most misread. On its own it tells you almost nothing — but used as a screen rather than a verdict, it’s genuinely powerful.
What the number really is
DSR is a composite of buyer interest signals (online views, search volume, days on market, auction clearance) divided by available stock (listings, vendor discounting, time on market trend). It is a snapshot of pressure — not a forecast.
What goes into a typical DSR score
- Listings & stock on market30%
- Buyer demand signals35%
- Days on market trend20%
- Vendor discounting15%
A high DSR confirms today’s pressure. It does not guarantee tomorrow’s growth.
Where it lies
- Thin markets. Tiny suburbs with 4 sales a quarter generate noise, not signal. Volatility ≠ trend.
- One-off stock shocks. A single estate release can collapse the ratio for two quarters and tell you nothing about underlying demand.
- Listing portal bias. Demand metrics derived from one portal under-weight off-market and agent-network sales.
- Renovator skew. Suburbs full of unrenovated stock distort price-per-sqm and discount data.

How to use it without being used by it
Treat DSR as the smoke alarm, not the fire report. It tells you where to look next, not what to buy. The shortlist is built on what survives the seven secondary screens above — and even then, only after a physical inspection and a strata / planning check.

FAQ
Frequently asked
- What is a good demand-to-supply ratio?
- Above 60 indicates strong buyer demand exceeding supply. Above 75 is exceptional and typically precedes 10%+ annual growth, though it also signals you may be paying near the cycle peak.
- Where can I find DSR data?
- Tools like SQM Research, PropertyValue, and DSR Data publish suburb-level scores monthly. NOVAQ clients receive curated DSR reports for shortlisted suburbs as part of the buyers agency service.
- Is DSR more reliable than median price growth?
- For short-term (6–12 month) forecasting, yes — DSR leads median price by 3–9 months. For long-term growth, fundamentals like population, infrastructure and zoning matter more.
