The one that is actually half built
The Mount Ousley interchange is the region's clearest piece of physical delivery. Transport for NSW's June 2026 update, its own progress document, states the project is 52 per cent complete. During a round of night closures in March, crews placed 3,500 tonnes of asphalt, replaced 464 metres of concrete barrier with 500 metres of new barrier, installed 55 metres of stormwater drainage and opened a new heavy-vehicle safety ramp. All 16 girders are in for the bridge over the heavy-vehicle bypass and all 20 for the pedestrian bridge, placed by a 150-tonne crane, with the concrete decks for both due to be poured from June.
The milestone that will matter to anyone who drives it: the first major traffic change, moving traffic onto a newly built section of Mount Ousley Road and a temporary bridge, is planned for mid to late 2026. That switch clears the ground for the new interchange itself, including a southbound heavy-vehicle bypass lane that will be cut about 3.5 metres below the existing road level, removing around 18,000 tonnes of material.
The funding is worth recording precisely, because it is the shape most of these projects aspire to: $390 million committed, $312 million Australian Government and $78 million NSW, contractor (Fulton Hogan) appointed, major work under way since late 2024 on a roughly four-year build. Those scope and funding facts date from the January 2024 contract award and the May 2024 delivery announcement; the 52 per cent and the traffic-switch timing are from the June 2026 update.
The one that is funded to plan, not to build
Picton Road, the region's other road out, reads very differently once you open the
project's own May 2026 update. Its words, exactly: All sections of the Picton Road
upgrade are currently funded for planning only. The timing of construction will be
subject to future funding decisions by the Australian and NSW governments.
That sentence deserves more circulation than it gets. On the western section, from the Nepean River to Almond Street at Wilton including the Hume Motorway interchange, the concept design, environmental assessment and assurance processes are complete and Transport is buying property and designing utility relocations. Property acquisition on a corridor with no committed construction budget is not nothing, it is how projects position themselves to build. But "approved and acquiring land" is not "funded", and the central and eastern sections of the roughly 30-kilometre corridor are still at the investigation stage, with surveys continuing through 2026 before options are even settled.
The health builds: two clocks, one program
The New Shellharbour Hospital is the region's biggest single project by committed dollars: $828.9 million from the NSW and Commonwealth governments for the hospital and integrated services project. Construction is under way and the hospital is expected to be complete in 2027, on a site acquired in August 2022, with the main-works contractor awarded in August 2024 and construction started that October. The Warrawong Community Health Centre, part of the same $828.9 million project, is expected to be completed in 2026.
A note on a number you may have seen: a May 2025 ministerial release described "more than $780 million" of Illawarra health infrastructure investment. The project page itself, checked this week, states the committed figure for the Shellharbour project as $828.9 million, and that is the figure we use here. The two numbers describe overlapping programs at different moments; they are not competing claims about the same thing, and neither should be added to anything else in this story.
Behind Shellharbour comes the Wollongong Hospital and Health Precinct: a $220 million commitment for the future expansion and redevelopment of what NSW Health calls the region's largest hospital. Its status, on its own page, is one word: planning. The concrete news is the appointment in late June of the lead design team, Johnstaff Projects as project managers, Billard Leece Partners as architects and Genus Advisory as cost managers, working with Health Infrastructure and the local health district. What will actually be built is, in the page's own words, to be determined following further planning. That is an honest gap, and we report it as one.
The winter 2026 status ledger
| Project | Committed | Stage right now | Next dated marker |
|---|---|---|---|
| Mount Ousley interchange | $390m | Construction, 52% complete | Traffic switch, mid to late 2026 |
| New Shellharbour Hospital | $828.9m | Construction | Completion expected 2027 |
| Warrawong Community Health Centre | part of the $828.9m project | Construction | Completion expected 2026 |
| Wollongong Hospital & Health Precinct | $220m | Planning; design team appointed | Scope to be determined |
| Picton Road upgrade (all sections) | planning only | West: acquisitions; centre/east: investigations | Investigations continue through 2026 |
| Dapto ramps (M1 access) | $30m for planning | Preferred option confirmed (Fowlers Road) | Planning progresses |
| Shellharbour breakwall repairs | $4m | Detailed design and planning | Construction expected to begin mid to late 2027 |
Committed figures are as stated by each project's delivery agency and cover different scopes (a road, a hospital program, a repair job). They must not be summed into a regional total; see the methodology note below.
Why we keep the ledger this way
Every project on this list has been announced at least twice: once when funded or proposed, and again at each milestone. Announcement language flattens the difference between a bulldozer and a business case. The delivery agencies' own project pages and update PDFs do not, which is why each row above traces to one. When a row changes stage, we will update the ledger and say what moved.
