Wilton new town sits where the Hume Motorway meets Picton Road, about 80 km south-west of the Sydney CBD. For years it was mostly a golf estate and a lot of paddocks. In 2026, though, it looks more like a real town in the making. The first public schools open in January 2027, and new motorway ramps are under construction. Still, the big Picton Road upgrade has no construction money, and one of the main estates is in receivership. So here is where each precinct stands, what’s funded, and what is still a plan.

How big Wilton new town gets
Wilton is one of the state’s priority growth areas, inside Wollondilly Shire. The NSW Government adopted the Wilton 2040 plan on 28 September 2018. Wollondilly Shire Council says Wilton new town will deliver 15,000 new homes over about twenty years. Local reporting on the August 2026 health hub announcement used a wider range of 15,000 to 17,000 homes. It also cited about 50,000 future residents across roughly 4,000 hectares.
The growth area has seven precincts. Council’s precinct summary page sets out the numbers for each one:
- North Wilton (Panorama). Rezoned in October 2018, about 874 ha, and up to 5,600 homes in roughly 10 stages over 25 years. Landcom is the developer.
- South East Wilton (Wilton Greens). Rezoned in 2017, 472 ha, and up to 3,600 homes.
- Bingara Gorge. Rezoned back in 2005, with around 1,800 lots around an 18-hole golf course.
- Wilton Town Centre. Rezoning took effect on 30 June 2023. It allows about 1,600 homes and up to 7,000 local jobs.
- West Wilton. Not yet rezoned. A draft planning proposal covers about 397 ha and 2,350 lots.
- South Wilton. Not yet rezoned, about 430 ha in five planning cells.
- Maldon. Set aside for employment only, at 562 ha.
Add up the residential precincts and you get close to 15,000 before South Wilton contributes anything. That matters. Council says it must first “clarify the dwelling cap matters” with the state before planning South Wilton for housing. In other words, the 15,000 figure works as a ceiling as much as a target.
North Wilton: where most of the action is
North Wilton is the state-led part of the new town, and right now it moves fastest. Landcom welcomed its first resident family in Stage 1 by mid-2025. After that, it finished civil works on Stage 4 in June 2025. Council’s precinct page now says housing development is in progress on Stages 2, 3 and 4. The plan includes a local centre of about 5,000 m², an 11-hectare lake and 415 hectares of environmental conservation land.
Money for local facilities is also firming up. In November 2025, council voted to exhibit a draft planning agreement with Landcom worth more than $35 million. That includes almost $25 million for open space, and council staff said it beats the baseline contributions by $11.7 million.
The biggest piece of road work is Landcom’s own. On 30 March 2026, crews started work on new Hume Motorway entry and exit ramps. The job also includes a new three-lane bridge over the motorway. Landcom is fully funding it, Seymour Whyte Constructions is building it, and completion is due in late 2027.
Wilton new town schools open in 2027
Until now, Wilton’s high school students have had to travel to Picton High School. That changes on Day 1, Term 1 2027. On a shared site on Fairway Drive in North Wilton, three new public facilities open together. First comes Wilton Ridge Public School, with 24 classrooms. Next to it sits a public preschool with 60 fee-free places. Then there is Stage 1 of the new Wilton High School.
The high school starts small, with up to 187 students in Years 7 and 8. Once Stage 2 finishes in 2028, it grows to capacity for up to 1,000 students. ADCO Constructions holds both contracts, and enrolments for 2027 are already open. Note that project pages list 200 Fairway Drive, while the high school release says 205.
Wilton new town’s town centre and health hub
The state plans the town centre as the largest strategic centre in Wollondilly. The zoning sets aside 127.7 hectares of urban development land and 36.7 hectares of conservation land. It also includes 28.9 hectares zoned for road and rail infrastructure. But a zone isn’t a shopping centre. In August 2026, council endorsed neighbourhood plans for the town centre and the 108-hectare Wilton Industrial Park next door. Developers have also lodged applications for the first town centre stage and a new signalised Picton Road intersection.
Health care is the other gap. On 27 August 2026, NSW Health announced plans for a Wilton Integrated Health Hub for non-acute care. It forms part of the state’s $11.9 billion program across 32 facilities. Yet NSW Health named no project budget or construction date. It also described land acquisition as the immediate priority. Local reports said the government had secured a site, so the accounts differ slightly.
Picton Road: planning money only
Picton Road carries about 22,000 vehicles a day, and 23% of them are heavy vehicles. Between 2019 and 2023 it recorded 88 crashes, with 5 deaths. Transport for NSW is planning an upgrade of about 30 km, from the Nepean River to the M1 Princes Motorway. It splits the job into three sections.
The Australian Government has committed $80.7 million and the NSW Government $44 million. However, that money covers planning and design only. The western section, from the Nepean River to Almond Street, has approval and property acquisition has started. By contrast, the central and eastern sections are still at the shortlist options stage. Transport for NSW says construction timing depends on “future funding decisions” by both governments. So for now, nobody has funded the build itself.
Rail, buses and the koala corridor
There is no passenger rail to Wilton, and no funded plan for any. The town centre zoning reserves land for road and rail, and council keeps lobbying for “electrified rail” and better buses. But no agency has published a rail business case, a route or a budget for Wilton. For now, getting around Wilton means driving.
Koalas are the other long-running issue. The Wilton 2040 vision promises to protect “its koala corridor”. Back in 2018, the then mayor and wildlife carers warned that the rezonings put koalas at risk, especially on Picton Road. Since then, Transport for NSW has added koala fencing on the Hume Motorway at Picton Road and near Allen’s Creek bridge. Even so, every new road crossing remains a test of whether the corridor actually works.
Wilton Greens and the receivership sale
South East Wilton has had a rough run. Walker Corp secured approval in 2019, and Risland broke ground in 2021. Then in 2024 Avantaus bought a 332-hectare portion for about $240 million. Avantaus entered receivership in November 2025. Agents then marketed stages 3 to 6, covering 2,396 lots plus retail land and a school site. Expressions of interest closed on 3 September 2026. So the pace of this precinct now depends on who buys it, and when.
What’s still missing / not confirmed
- Construction funding and a start date for any section of the Picton Road upgrade.
- A buyer for the Wilton Greens stages, and a timeline for those 2,396 lots.
- A site, budget and opening date for the health hub.
- Approval of the town centre’s first stage, and an anchor tenant.
- Rezoning decisions for West Wilton and South Wilton, plus the dwelling cap question.
- Any rail route, business case or funding.
My take: Wilton new town finally has the basics that turn an estate into a suburb. Schools open in 2027 and new motorway ramps follow late that year, which is real progress. But I wouldn’t price in Picton Road or a train. The road is the daily bottleneck for anyone working in Wollongong or Campbelltown, and it has planning money only. So buy here for the land price and the 2027 schools. Then assume your commute stays much the same until about 2030.
Also, a receivership sale can stall unreleased stages for years. That’s why I’d lean towards North Wilton for now, since a government developer is funding its own roads.
