Stockland's Sienna Wood enters its next phase as Hilbert community infrastructure comes online

Stockland's Sienna Wood has reached a different stage of its development in Hilbert, with two of the masterplanned community's major pieces of infrastructure opening in 2026 while new residential lots continue to be released.

Wungong Primary School welcomed its first students in February, followed by the opening of Sienna Wood Town Centre in May, bringing a full-line Woolworths, specialty stores, dining, medical services and childcare into the community.

The additions build on infrastructure already delivered throughout Sienna Wood, including several major parks, walking trails, conservation areas and community facilities, as Stockland progresses the approximately 3,800-property development towards its estimated 2031 completion.

About Sienna Wood

Sienna Wood is around 34 kilometres south-east of the Perth CBD, with access to Tonkin Highway and the broader arterial road network. Existing destinations nearby include Armadale's retail and health precincts, while the estate itself now provides an increasing proportion of its everyday infrastructure.

Stockland is continuing to release land as infrastructure comes online, with new lots currently ranging from 263 sqm to 561 sqm and further releases scheduled monthly. A $5,000 deposit initiative is also available on eligible land purchases.

A defining part of the masterplan is the amount of land retained as open space. Stockland has allocated 39 per cent of Sienna Wood to open space, around four times the minimum requirement for new developments.

That includes a 13.3-hectare conservation area, which Stockland says is two-thirds rehabilitated and planted, as well as the revitalised Neerigen Brook. New footpaths and limestone trails provide connections through the community, including between Shipwreck Park and Eleventh Road.

The recreation network has also expanded as the community has grown. Shipwreck Park was delivered as a $4.8 million all-abilities playground, while the $2.6 million Explorer Park includes an eight-metre-high "tree of life" play structure and tunnel slides. Dinosaur Park provides another playground within the estate, while basketball courts, table tennis, football goals and cricket nets are distributed across its parks.

The opening of Wungong Primary School has added another piece of infrastructure directly within the community. The $41 million Kindergarten to Year 6 school opened for Term 1 in February 2026 to serve the growing Hilbert and Wungong area.

Three months later, Sienna Wood Town Centre opened opposite Shipwreck Park. The centre has shifted everyday retail and services closer to homes within the development, with Woolworths accompanied by specialty stores, food and dining options, medical services and childcare.

Those additions come as the surrounding south-east Perth corridor continues to expand.

Urbis research prepared for Stockland identified Hilbert and Haynes as part of the high-growth Armadale-Wungong-Brookdale area. Its February 2025 report forecast the broader statistical area's population to increase from 23,166 in 2021 to 33,455 by 2031, representing average annual growth of around 3.1 per cent.

The report pointed to new housing, public transport, education and employment opportunities as contributors to that growth. Major infrastructure identified in the surrounding region included the Byford Rail Extension, Armadale Station upgrade, Tonkin Highway Extension and the developing Forrestdale Business Park West.

Bottom line

Sienna Wood's monthly land release cadence, combined with a $5,000 deposit offer, gives buyers a relatively low-friction way to secure a lot in one of Perth's more established south-eastern growth corridors, one where key community infrastructure, including a new town centre and primary school, has already been delivered rather than promised for some distant future stage.

With median prices in Hilbert and Haynes still sitting below the Greater Perth benchmark and price growth outpacing the broader market, the area continues to offer a comparatively accessible entry point for first-home buyers and upgraders.

For those ready to pair land with a build, Perth's south-east sits within reach of a wide spread of established builders, from first-home specialists to full-service custom builders, giving buyers meaningful choice.
