In the 2025-26 financial year the ABS recorded 1,145 dwelling approvals across Wollondilly. Right now, 272 development applications are before the 2 councils covering the area. AreaSearch tracks 38 major projects here that are committed or under construction, the largest being Appin (Part) Precinct - Future Appin Communities at an estimated $12.5bn. On the ground, 4,155 new addresses have been verified since the 2021 Census — growth of 23.6% on the existing address base.
These four figures are deliberately not added together. An application, an
approval and a project under construction are often the same building at three points in its life,
measured by three different bodies with three different lags. Read them as a sequence, not a total.
ApprovedBuilding Approvals in Wollondilly
What councils and certifiers have formally
permitted — the ABS series, published about four months in arrears.
Approvals are running at 1.81 per 100 existing dwellings a year, well above the New South Wales rate of 0.59. The mix is genuinely split — 74% of recent approvals are detached houses and 26% are attached or higher-density dwellings. Detached houses make up 94% of the homes already standing here but only 77% of the past five years of approvals, so the area is densifying. The average approved dwelling is valued at $413,000 in construction cost.
For its size, Wollondilly is adding 1.81 dwellings a year per 100 existing homes — well above the New South Wales rate of 0.59 and the national rate of 0.71. That is about 15.4 approvals a year for every 1,000 residents. Building intensity has risen by about 137% across the published series.
Measured against people rather than housing stock, Wollondilly is approving 21.76 dwellings a year per 1,000 residents — well above the New South Wales rate of 6.06. The two rate views differ by household size, which here averages 3.1 people per home. Housing the projection to 2041 would need about 14.80 per 1,000 residents a year.
Dwelling approvals a year per 100 existing
homes, with New South Wales and Australia for comparison. This is the
same activity as the totals view, divided by the size of the area — which is the only
fair way to compare a large SA3 with a small one.
Dwelling approvals a year per 1,000
residents, each year divided by that year’s estimated resident
population (ABS ERP at 30 June), not by today’s — which matters most in fast-growing
areas, where a fixed denominator can understate the early years by half. The most recent periods use the latest published ERP, as the population series runs a year behind approvals. Read it alongside the per-100-homes view: the two differ wherever household size does.
Dwelling units approved each financial year. The dashed line is the five-year average of 843.

Supply & DemandIs Wollondilly Building Enough Homes?
The same approvals, measured against the population
they have to house.
Wollondilly approves about 15.4 new dwellings a year for every 1,000 residents. Since the 2021 Census it has added 8,916 residents and 4,155 new addresses — about 2.1 extra people per home built, below the 3.1-person average household, so building has run ahead of population growth. Housing the population projected for 2041 implies roughly 810 new dwellings a year from here, which puts the recent approval rate of 843 a year about level with what the projection needs.
Growth against supply since the Census
People added for every new address verified,
against the size of an average local household.
People added per new home2.1
Average household size3.1
A bar longer than the household average means
the area gained more residents than its new housing could hold, and the extra had to be
absorbed by existing homes.

What is being asked for right now — applications
collected from council planning portals, before any of it reaches the ABS series above.
AreaSearch tracks applications of material scale; routine minor works such as signage and
fencing changes are not carried, so these are not counts of every application lodged. 31
of them carry an AreaSearch analyst assessment — look for the
Analysed marker in the search below.
AreaSearch tracks 2,059 development applications of material scale lodged with councils across Wollondilly, the most recent in September 2026. 272 of them are still in assessment. The biggest categories in the queue by value are mixed-use, commercial and retail.
Estimated value of applications by development type. This is the clearest

DistributionWhere Development Is Happening in Wollondilly
Wollondilly covers 4 statistical areas, and development is not spread evenly between them. Douglas Park - Appin alone accounted for 59% of the area’s dwelling approvals in 2025-26.
Approvals per 100 existing homes in
2025-26, by statistical area, with the Wollondilly figure marked. Ranked
rather than stacked: rates cannot be added together.
Approvals per 1,000 residents in 2025-26,

Wollondilly figure marked. A small area building hard is invisible in
the totals view and obvious here.
Dwelling approvals each financial year, split by the statistical area they
fell in. Each column totals the whole Wollondilly figure from the
approvals chart above — SA2s nest exactly inside an SA3, so the two always reconcile.

Map builder
Each area below opens a map builder on its own page — a tool for
putting a map and a table into a report. Pick the place types you want plotted
(schools, supermarkets, medical, child care, transport and the rest of what
AreaSearch holds), add development applications as their own layer, drop your own
points, then recolour, renumber and export the result as a table or CSV.
A this area only toggle clips everything to the boundary you are looking at.
Searches are charged against your credit balance — 1 credit per 40
results from AreaSearch data — and setting filters costs nothing until
you search. The builder works on one suburb-sized area at a time, which is why it
opens per area rather than across the whole of
Wollondilly.
Wollondilly spans 2 local government areas — Wollondilly and Wingecarribee. Applications here are assessed by whichever of those councils the site falls within. AreaSearch publishes development
figures at ABS statistical boundaries rather than council boundaries. That is deliberate: the ABS
issues a separate official building-approvals series for local government areas, and totals
built up from statistical areas would not match it. Reporting at SA3 keeps every figure on this page
reconcilable with the published ABS series.

CompareNearby Development Hubs
The same view of building approvals, applications and
major projects for areas neighbouring Wollondilly.
Collected from council planning portals. The
earliest signal available, but the least certain: many applications are amended,
withdrawn or refused, values are the applicant’s own estimate, and coverage
varies by council. This is a curated set, not the full council feed:
AreaSearch carries applications of material scale and does not track routine minor
works such as signage, fencing or small alterations, so the counts here are lower
than a council’s own total lodgement figure and should not be compared with it. Applications still shown as under assessment more than
18 months after lodgement are reported separately
and kept out of the live-queue figures: the age profile of open applications is
sharply split between a genuine queue under a year old and a long tail of records
councils never closed. Not every state publishes a cost of works — Queensland,
the Northern Territory and the ACT publish none at all — so on those pages
applications are counted rather than valued and no dollar figure is shown
rather than a partial one. Treated here as a snapshot of the current queue only —
AreaSearch does not chart application counts over time, because the history
reflects when each portal was collected rather than when development happened.
Approved — ABS building approvals
The official series, aggregated to SA3 from
ABS building approvals data, currently published to August 2026.
Counts dwelling units approved, not buildings and not completions. The most recent
financial year is annualised from nine months of data wherever it appears and is
labelled as such.
Building — major projects
Projects tracked individually by AreaSearch
from Infrastructure Australia, state infrastructure agencies, developer disclosures
and council records. Values are estimates and delivery dates are targets. Ranked on
this page by committed value and delivery stage rather than by distance.
Delivered — verified new addresses
New residential addresses verified in the national
address register since the 2021 Census. This is the closest available measure of what has
actually been built, though address creation can lead occupation and lags
construction. It is not a completions count.

How many new dwellings were approved in Wollondilly?
The ABS recorded 1,145 dwelling approvals across Wollondilly in the 2025-26 financial year, against a five-year average of 843 a year.
How many development applications are lodged in Wollondilly?
AreaSearch tracks 2,059 development applications of material scale across Wollondilly — routine minor works such as signage and fencing are not included, so this is not a count of every application lodged, of which 272 remain in assessment. Applications are assessed within the Wollondilly and Wingecarribee local government areas. The most recent application in our data was lodged in September 2026.
What major projects are planned for Wollondilly?
AreaSearch tracks 38 current major projects in Wollondilly, 13 of them under construction. The largest include Bingara Gorge, Appin Mine Ventilation and Access Project and Wilton Ridge Public School, Public Preschool and Wilton High School.
Which council covers Wollondilly?
Wollondilly is an ABS Statistical Area Level 3. It is covered by parts of 2 local government areas — Wollondilly and Wingecarribee. AreaSearch publishes development figures at ABS statistical boundaries rather than council boundaries, so they reconcile with the official ABS series.
Is Wollondilly growing faster than the rest of New South Wales?
On development approvals, Wollondilly is adding new dwellings faster than New South Wales as a whole — 1.81 approvals per 100 existing dwellings a year against the state figure of 0.59.
How current is this development data?
ABS building approvals are published with a lag of roughly four months; this page carries the series to August 2026. Development applications are collected from council planning portals and refresh continuously, with the most recent application here lodged in September 2026. Major project records are reviewed on an ongoing basis. Each section carries its own currency label so the four are never confused.
Development data is provided for general information.
Estimated values, dwelling counts and delivery dates come from the lodging or delivering party and
are not independently verified by AreaSearch. Confirm anything material with the relevant council
or agency before relying on it.
