How the Housing Supply Pipeline Works
📋 Approvals & Starts
New dwelling approvals and commencements are both running a little above their fifteen-year averages, the highest since 2021, and the gap between them is unremarkable. The inflow of new supply is normal to slightly firm.
A little above average🏗️ Homes Under Construction
The stock of homes being built is at a record, and the value of residential work still to be finished is about double its fifteen-year average, also a record. Work completed each quarter is also above average.
Record high🏦 Construction Finance
Bank lending limits for land development and actual lending to construction businesses are both far above their fifteen-year averages. The insolvency count for late 2025 is not yet published.
Elevated, partly unseenAustralian Property Network tracks the supply of new housing as three sequential stages rather than one headline number, because the three can — and right now do — tell different stories. Each stage is a separate node in the APN Codex, measured against fifteen years of history so that a reading can be judged as unusual or ordinary rather than simply large or small.
Each measure is scored by how far it sits from its fifteen-year average, in units of that measure’s own normal variation. A score of zero means exactly average. A score of +1 means about one standard deviation above average — unusual but not rare. A score of +2 or more is a level seen in only a handful of quarters over fifteen years. Negative scores mean below average. Each node combines its measures into a single composite score.
Gold bars are the six pipeline measures at the June quarter 2026. Slate bars are the two lending measures at the December quarter 2025, the latest quarter certified for Construction Finance & Capacity (21530). The dashed lines mark +1 and +2: beyond +2 is a level seen in only a handful of quarters. Source: APN Codex certified readings; baseline 2011 to 2025.
In the June quarter of 2026, 53,952 dwellings were approved and 52,166 were commenced. Both are a little above their fifteen-year averages of roughly 48,900 and 48,200 respectively, and commencements recovered from 45,777 in the March quarter. The gap between approvals and commencements — the number of homes approved but not yet started — was 1,786, a little above its average of about 770, but well inside the range the series treats as normal. Node 21510’s composite score of +0.4936σ is about half a standard deviation above average, its highest reading since the September quarter of 2021.
The two lines track each other closely, so the gap between them is usually small. The June quarter 2026 ends at 53,952 approved and 52,166 commenced. The largest quarter of commencements, 66,769 in June 2021, followed the HomeBuilder approvals of the quarters before it.

| Measure | Q2 2026 | 15-year average | Score | Read |
|---|---|---|---|---|
| Dwellings approved | 53,952 | 48,927 | +0.6369σ | A little above average |
| Dwellings commenced | 52,166 | 48,157 | +0.5146σ | A little above average |
| Approvals minus commencements | 1,786 | 770 | +0.3294σ | A little above average; not a warning |
| Node 21510 composite | — | — | +0.4936σ | A little above the 15-year mean |
The gap between approvals and starts only becomes a warning sign when its score passes 1.5 in either direction. It has done so in just seven quarters since 2011. The most recent breach was the March quarter of 2023, and it ran in the opposite direction to a stall: commencements outpaced approvals. The December quarter of 2025 came close on the same side without crossing. There is no backlog of approved-but-unstarted homes building up at the front of the pipeline.
Once a dwelling is commenced it joins the stock under construction. At the June quarter of 2026 there were 248,733 dwellings under construction — about a quarter above the fifteen-year average of roughly 198,000, and the most on record. The value of residential building work still needed to complete them was $84.7 billion, against an average of about $42 billion: about double, and the highest reading in the series. Residential building work actually completed in the quarter was $27.9 billion, about 17% above average.
On this scale the two measures can be compared directly. Dwellings under construction end at 125, about a quarter above average. Work yet to be done ends at 202, about double. The two lines moved together until 2021 and have separated since. Work yet to be done is in current prices. Source: Australian Bureau of Statistics, Building Activity, Australia, June quarter 2026; APN calculation, average of 2011 to 2025 = 100.
The important comparison is between the first two figures. The count of homes under construction is about 25% above normal; the money needed to finish them is about double its normal level. The value of the unfinished pipeline has grown far faster than the number of homes in it, which means each home still under construction carries, on average, more unfinished cost than it used to. That is what structural cost inflation looks like in the data: not a stalled industry — output is above average — but an industry whose backlog is growing more expensive faster than it can be worked off. The value of residential work yet to be done has set a new high in each of the last eight quarters.
A kitchen with orders coming in at the usual rate, more dishes on the go than ever, each dish more elaborate and expensive than before, and chefs plating up faster than average — yet the queue of unfinished orders keeps growing. Nothing is broken at the front door. The pressure is all in what is already on the pass.
The third node measures whether the sector has the financial capacity to deliver. Its latest certified reading is for the December quarter of 2025, two quarters behind the other two nodes, because one of its inputs is published on a slower cycle. As at that quarter, bank lending limits for land development stood at $32.4 billion and actual bank lending to construction businesses at $12.9 billion — both far above their fifteen-year averages of roughly $21.4 billion and $6.8 billion.
Lending limits ended 2025 at $32.4 billion, against an average of about $21.4 billion. New lending to construction was $12.9 billion in the December quarter, against an average of about $6.8 billion; it swings from quarter to quarter and is usually highest in the December quarter. Sources: Australian Prudential Regulation Authority, Quarterly Authorised Deposit-taking Institution Property Exposures; Australian Bureau of Statistics, Lending Indicators.
The node is designed to subtract a construction-insolvency signal from the lending signals, so that a wave of builder failures pulls the score down. That insolvency data comes from the corporate regulator once a year, and the figures for the second half of 2025 will not be released until December 2026. In the meantime the score treats insolvency as neutral. The +2.1333σ reading therefore reflects lending capacity fully but says nothing yet about the financial health of the businesses doing the building. Roughly a fifth of the score’s intended signal is absent, not incorporated.
The front of the pipeline has moved through four distinct phases since 2011. Reading the current position against them is what separates a normal quarter from a genuinely unusual one.
| Phase | Years | Approvals & starts (21510) | Pipeline depth (21520) |
|---|---|---|---|
| 1 · Post-GFC weakness | 2011–2014 | Below average throughout, as low as −1.39σ in late 2011 | Deeply below average; the shallowest pipeline in the record |
| 2 · Expansion | 2015–2019 | Above average, peaking at +1.68σ in the September quarter of 2016; easing back below average from late 2018 | Crossed above average in 2015 and stayed there to 2019 |
| 3 · HomeBuilder spike | 2020–2022 | Pandemic dip, then a stimulus surge to +1.25σ in the March quarter of 2021 as approvals ran ahead, followed by a record quarter of commencements as they caught up | Dipped in 2020, then began climbing as the stimulus starts entered the pipeline |
| 4 · Contraction and recovery | 2023–2026 | Sharply below average in 2023–24 (−1.38σ in early 2023), recovering through 2025 to the mean by early 2026 and a little above it in the June quarter (+0.49σ) | Rising every quarter since late 2023, from +0.44σ to +1.82σ, the highest on record |
The gold line swings above and below zero with each cycle and ends at +0.4936σ. The slate line has risen in every quarter since the December quarter 2023 and ends at +1.8182σ, its highest on record. Source: APN Codex node readings; baseline 2011 to 2025.
The pattern to notice is that the two nodes have parted company. The inflow has come back to around normal, but the pipeline behind it has kept deepening. That combination — a normal front door and a record backlog — is the defining feature of the current reading.
- The inflow is normal to slightly firm. Approvals and starts are a little above their fifteen-year averages. There is no approval boom and no approval slump.
- The backlog is the story. The value of residential work still to be done is the highest on record and has set a new high in each of the last eight quarters.
- This is not a stalled sector. Work completed is above average. The backlog is growing because it is getting more expensive to finish, not because nothing is being finished.
- Finance is available — to those who can get it. Lending limits and lending volumes are both far above average, which tends to favour larger, established operators.
- Watch December 2026. The construction insolvency figures for late 2025 arrive then, and they could move the finance score materially.
- Cost pressures are structural. Materials, labour and the 2022 building code all raised the cost of completing a home, and none of them reverses quickly.
