Alkimos was empty coastal scrubland twenty years ago. In 2026, it has a train station, a Costco-anchored trade hub on the way, and an $82.9 million aquatic centre about to open. Here’s every live Alkimos development, its actual location, and what it costs.

Alkimos Development 2026 — The Pipeline
Alkimos sits on Perth’s northern coastal corridor, between Joondalup and Yanchep, roughly 42 kilometres north-northwest of the CBD. In fact, the state government designated the wider Alkimos-Eglinton area a satellite city back in 2006, projecting 55,000 eventual residents. It wasn’t even counted in the 2011 census. By 2021 it had 10,203 people, and by 2025 housing estates had filled most of the suburb’s northern and southern halves — which is exactly the pattern that now makes town-centre infrastructure the priority, not more rooftops.
Unlike Queensland’s EDQ-run Priority Development Areas or Victoria’s VPA-planned growth corridors, Alkimos runs through a different governance model again. DevelopmentWA, the Western Australian state government’s own land agency, both plans and directly develops the Alkimos Central precinct — it sells the land itself rather than just approving someone else’s structure plan. The City of Wanneroo still holds the local planning approval power through its own structure plans, including Alkimos City Centre Activity Centre Structure Plan No. 89 and Central Alkimos ASP No. 95, but DevelopmentWA is both landowner and master developer in a way EDQ and the VPA are not.
Alkimos, WA — By the Numbers
PROJECT 1 — Home X Trade Hub (Costco Anchor)
STATUS: APPROVED, EOI PROCESS CLOSED
Costco is indeed coming to Alkimos Central, and the Cook Labor Government confirmed it in an October 2025 media statement from Planning and Lands Minister John Carey. The Home X Trade Hub sits within Alkimos Central, a short walk from Alkimos METRONET Station, with direct Mitchell Freeway access via Romeo Road. The site runs to 24 hectares in total, with up to 17 hectares still available for other commercial operators — DevelopmentWA closed the expression-of-interest window for those remaining sites on 26 November 2025.
Still, the government statement promises “hundreds of jobs” once the hub is trading, and neither DevelopmentWA nor Costco has published a construction start date or an opening date. Costco itself confirmed the Alkimos site as part of a broader Australian expansion — the retailer is adding warehouses nationally through 2027 — but it hasn’t announced when the doors open here specifically.
The marked area above shows the vacant, graded land within Alkimos Central where the Home X Trade Hub is expected to sit — DevelopmentWA hasn’t published exact site boundaries yet, so treat this as the general precinct rather than a confirmed lot line.
PROJECT 2 — Alkimos Aquatic & Recreation Centre
STATUS: UNDER CONSTRUCTION, OPENING NOVEMBER 2026
This is the one Alkimos residents can actually watch happening. The Aquatic and Recreation Centre sits at Koomool Dr, Alkimos WA 6038, immediately beside Alkimos Station and just north of Romeo Road, on a 3.5 hectare site. PS Structures won the construction contract in December 2024, and then broke ground in January 2025. As of August 2026, the City of Wanneroo confirmed the eight-lane 50-metre outdoor pool — the first of its kind in the city — had begun filling with water, with the indoor pools and splash pad next in line before testing ahead of a November 2026 opening.
In total, funding runs to $82.9 million, split across four sources: $30 million from the Australian Government, $12.6 million from the WA State Government, $14.2 million through a developer contribution plan, and $26.1 million from the City of Wanneroo itself. Once open, it’ll include the 50-metre outdoor pool, a 25-metre indoor lap pool, leisure pools, four indoor courts for netball, basketball, soccer and volleyball, a gym, a health suite with spa and sauna, a crèche and a café. Bluefit Pty Ltd signed on as operator in February 2026.
The marked site above is Koomool Dr, Alkimos WA 6038 — the actual Aquatic and Recreation Centre address, immediately south of Alkimos Station.

PROJECT 3 — Alkimos Retail Precinct (Centuria)
STATUS: PUBLIC CONSULTATION
Centuria Capital struck its land deal with the WA state government in September 2025, reported at the time as a $33 million retail precinct. The project has since moved into public consultation with a more specific figure attached: a $25 million complex on Marmion Avenue, Alkimos — just 80 metres from Alkimos Station. The anchor is a 2,400 square metre full-line supermarket, backed by 20 single-storey commercial tenancies: nine retail outlets, six cafés and restaurants, a fast-food outlet, a medical centre, a liquor store and a childcare facility, plus 301 car parking spaces and four EV charging bays.
Once planning consent clears without major changes, site works could start in 2026, with a typical 12-to-18-month build for a centre this size — which lines up with DevelopmentWA’s own timeline pointing to a Stage One Retail Precinct opening in 2027.
PROJECT 4 — Alkimos METRONET Station
STATUS: COMPLETED 2024
This one, however, is already delivered, and it’s the reason every other project on this page exists where it does. Alkimos Station opened on 14 July 2024 as part of the Yanchep Rail Extension, sitting north of Romeo Road and east of Marmion Avenue. It runs two side platforms sunk into a cutting, an eight-stand bus interchange, 615 car parking bays, and a 41-minute train run to Perth Underground at peak five-minute frequencies. Every project in this article — the trade hub, the aquatic centre, the retail precinct — sits within easy walking distance of it, which is the entire point of Alkimos Central as a transit-oriented town centre rather than another car-dependent shopping strip.
Who Actually Approves an Alkimos Development Application
DevelopmentWA is unusual among the state agencies this series has covered. In Queensland, EDQ assesses and approves applications inside its Priority Development Areas but doesn’t own the land. Victoria works differently again: the VPA writes the Precinct Structure Plan and then hands approval power to the local council. Alkimos goes a step further still, because DevelopmentWA does both jobs at once: it owns the Alkimos Central land, sells it to developers like Centuria, and works to its own master plan — while the City of Wanneroo still runs the formal structure-plan approval process underneath it, through instruments like Structure Plan No. 89 and ASP No. 95.
So in practice, that means a DevelopmentWA “yes” carries more weight in Alkimos than an EDQ or VPA sign-off does elsewhere, because DevelopmentWA is also the seller. A private buyer negotiating with Centuria or another future tenant is, at the same time, negotiating around land DevelopmentWA controlled from the start.
What Has Not Been Confirmed
- Costco and the Home X Trade Hub still have no construction start date or opening date
- The remaining 17 hectares of the trade hub site have no named tenants yet
- The Centuria retail precinct has no confirmed construction start — it’s still in public consultation
- Central Square and the station-area park have no confirmed date beyond a general 2026 timeframe
- First residential lot releases inside Alkimos Central also lack a confirmed date, currently pointed at 2027
For now, treat anything more specific than what’s listed above as speculation until DevelopmentWA, the City of Wanneroo or the relevant developer confirms it directly.
Alkimos follows a familiar pattern from earlier stops in this series — the transit-anchored retail hub in Wyndham Vale, Victoria and the EDQ-approved town centre push in Ripley Valley, Queensland both lean on the same formula: get the train station in first, then build retail and community infrastructure around it. Alkimos is simply the most literal version of that formula, because DevelopmentWA controls both the land and the timeline.
What Buying in Alkimos Right Now Actually Means
The train station is real and running, and the aquatic centre is real, funded, and months from opening. Meanwhile, everything else — Costco, the retail precinct, Central Square — is approved or in consultation, not built. Anyone buying in Alkimos today is buying into a town centre that’s roughly one-third delivered, banking on DevelopmentWA and its private partners finishing the rest on the timeline they’ve published.
Streets like this one show what a finished stage of Alkimos actually looks like — established housing, footpaths and street trees, the end state every project on this page is building toward.
Alkimos Central — What’s Actually Ready
The Bottom Line on Alkimos Development
Bottom line: DevelopmentWA has delivered the train station, funded and is finishing the aquatic centre, and locked in Costco as an anchor — but the retail precinct is still in consultation and Central Square hasn’t broken ground. Alkimos in 2026 is a town centre under construction, not a finished one.
FAQ
Is Costco actually coming to Alkimos?
Yes — the Cook Labor Government confirmed Costco as anchor tenant of the Home X Trade Hub in Alkimos Central in October 2025. No opening date has been announced.
When does the Alkimos Aquatic and Recreation Centre open?
The City of Wanneroo is targeting November 2026. As of August 2026 the outdoor 50-metre pool had begun filling with water ahead of testing.
Where exactly is the Alkimos retail precinct?
On Marmion Avenue, Alkimos, about 80 metres from Alkimos Station. Centuria Capital is the developer, and the project is currently in public consultation.
How is Alkimos different from Wyndham Vale or Ripley Valley?
DevelopmentWA owns and sells the land itself, on top of setting the master plan — unlike EDQ in Queensland or the VPA in Victoria, which approve or plan without owning the land outright.
This article covers publicly available planning, council and state government information current as of publication. Approved plans and timelines can change during construction; always confirm tenancy and opening details directly with DevelopmentWA, the City of Wanneroo or the relevant developer before making decisions based on this article.
