Where NSW Strata Disputes Actually Happen
If you assumed NSW strata disputes cluster where the apartments are, the data says otherwise. We joined 2,130 published NSW court and tribunal decisions to 88,825 strata plans and worked out the dispute rate per 1,000 strata lots for every suburb with meaningful apartment stock. The result is close to an inversion of the apartment map.
Sydney's western and north-western apartment belt — the suburbs that have absorbed most of the last decade's density — barely appears in the published record at all. The old, expensive, harbourside suburbs appear constantly.
Two suburbs, one number
Start with the sharpest pair in the dataset.
Wentworth Point
0
published decisions, across 7,914 strata lots
Rose Bay
16
published decisions, across 3,303 strata lots
Wentworth Point holds 2.4 times as many strata lots as Rose Bay and has never produced a published strata decision we can link to it. Rose Bay has produced sixteen. Same state, same Strata Schemes Management Act, same tribunal, same owners corporation rules about levies, by-laws, repairs and committee elections.
That is not a rounding difference. It is the kind of gap that means the thing being measured is not what you first assumed it was — and working out what it actually measures turns out to be more useful to a buyer than the headline.
Disputes per 1,000 lots, ranked
Raw case counts just tell you where the apartments are, so we normalised. Every suburb below holds at least 3,000 strata lots — 98 suburbs qualify, covering 535,323 lots between them. Across that whole set the baseline is 1.23 published decisions per 1,000 lots. Here are the suburbs furthest above it.
Highest dispute rate (decisions per 1,000 strata lots)
Bracketed figure is the raw number of linked decisions. Baseline across all 98 suburbs: 1.23.
Every one of the top twelve is an eastern suburb, lower north shore, or inner-city. Rose Bay, Elizabeth Bay and Bellevue Hill run at roughly three and a half times the state baseline.
Now the other end of the same list.
| Suburb | Strata lots | Decisions | Per 1,000 |
|---|---|---|---|
| Wentworth Point | 7,914 | 0 | 0.00 |
| Lidcombe | 6,654 | 0 | 0.00 |
| Penrith | 5,846 | 0 | 0.00 |
| Dulwich Hill | 3,586 | 0 | 0.00 |
| Mount Druitt | 3,141 | 0 | 0.00 |
| Penshurst | 3,015 | 0 | 0.00 |
| Wentworthville | 3,010 | 0 | 0.00 |
| Castle Hill | 5,847 | 1 | 0.17 |
| Blacktown | 5,731 | 1 | 0.17 |
| Westmead | 5,303 | 1 | 0.19 |
| Lakemba | 3,904 | 1 | 0.26 |
| Granville | 3,828 | 1 | 0.26 |
Seven suburbs with more than 3,000 strata lots each have zero linked published decisions. Between them, Wentworth Point, Lidcombe, Penrith, Dulwich Hill, Mount Druitt, Penshurst and Wentworthville hold over 32,000 strata lots and produce no published strata case law at all. Castle Hill, Blacktown and Westmead have one each.
The obvious objection, tested
There is one explanation that would dissolve this whole finding, and it deserves to be dealt with before anything else: the buildings are different ages.
Our decision set runs from July 1999 to August 2026 — 27 years. The denominator is the current lot count. Rose Bay's apartment blocks existed for that entire window. Wentworth Point's towers largely did not; most of that suburb is a decade old or less. A suburb can hardly litigate before it is built. So the gap could be an artefact of counting modern stock against a historical case record.
We tested it rather than publishing the caveat and moving on. Restricting to decisions from 1 January 2018 onward — a window in which the Wentworth Point, Lidcombe and Westmead towers all exist and are occupied:
Decisions from 2018 onward, per 1,000 lots
Rose Bay stays first — 4.84 falls only to 4.24, because 14 of its 16 decisions are post-2018. The leading group is the same set of suburbs in a slightly different order. The zero-decision suburbs stay at zero.
The reason the restriction changes so little is that the case volume is genuinely recent: 78 decisions in 2019, 71 in 2020, 92 in 2021, 122 in 2022, 106 in 2023, 91 in 2024, 149 in 2025 and 74 in 2026 so far. More than 85% of linked decisions fall inside the 2018+ window already.
Verdict: “old buildings, young data” does not carry the pattern. The gap survives the fairest time window we can construct.
What actually explains the gap
With building age ruled out, the strongest remaining explanation is uncomfortable and more interesting than the headline: litigating to a published decision costs money.
Getting to a published NCAT or Supreme Court judgment generally means lawyers, expert reports, and an owners corporation willing to spend from its administrative fund for months or years. A dispute in a building where lots trade for $3 million has more at stake per lot, and an owners corporation with deeper pockets, than the same dispute in a building where lots trade for $600,000. The first fights it out. The second settles, or lets it go.
On that reading, this is not a map of where strata problems occur. It is closer to a map of where owners can afford to fight about them. A zero in Wentworth Point does not mean nothing goes wrong there; it means whatever goes wrong does not reach a published judgment.
Two other explanations remain live and we cannot separate them with this dataset. Disputes over heritage fabric, harbour views, balcony works and short-term letting — the recurring subject matter in the top suburbs — may genuinely be more litigable than the defect and levy disputes that dominate newer stock. And published decisions are the visible tip: most strata disputes settle, conciliate, or end at an unpublished order that never enters any database, ours included.
What this means if you're buying
The practical takeaway is a warning about how to read a clean record.
A suburb with no cases is not a suburb with no problems
If you are buying in the western or north-western apartment belt, the absence of tribunal history in the area tells you very little. Nearly the entire belt reads zero. Use the building's own financials, its capital works fund and its defect history instead — those signals exist everywhere, and they do not depend on someone having paid a barrister.
A case in a high-rate suburb is weaker evidence than a case in a low-rate one
One decision against a Rose Bay building sits in a suburb running at nearly four times the state baseline — it is closer to normal there. One decision against a Blacktown building is one of only two in a suburb of 5,731 lots. The same single case means something quite different depending on where it is.
Read the subject matter, not just the count
A by-law dispute about a pet and a $37 million building defect claim both count as one decision. The count is a starting point for reading the actual judgment — which is public and free on caselaw.nsw.gov.au.

Methodology and limits
Data. 2,130 published NSW court and tribunal decisions involving strata schemes, scraped from the public record, joined to 88,825 NSW strata plans by the strata plan numbers cited in each decision. Suburb comes from the plan record, not the decision text. Lot counts are current registered lot totals. Analysis run 9 August 2026.
Universe. Only suburbs with 3,000 or more strata lots are ranked — 98 suburbs, 535,323 lots. Below that threshold a single case swings the rate wildly.
Coverage limit, and it is a real one. Only 1,159 of the 2,130 decisions (54%) carry a strata plan number we can extract and match to a plan. If plan-number extraction fails at different rates for different kinds of decision, the geography of the decisions we can place on a map is not necessarily the geography of all decisions. We have not measured that, so read every figure here as disputes we can locate, not all disputes.
Rate limit. The rate is decisions per current lot, not per lot-year, so it does not adjust for how long each building has existed. The 2018+ cut above is our best available correction for that, not a complete one.
