Cogplex is a client-side project management consultancy based in Busselton, Western Australia. We work on behalf of project owners across hospitality, tourism, residential and commercial developments throughout WA.
Our value is concentrated at the front end of a project. Before consultants are engaged, we model a development’s feasibility, planning fit, design intent and procurement strategy - so the brief handed to the specialist team is clear, tested and commercially sound.
We lead the project through approvals to completion, holding the brief, the consultant team and the commercial outcome together. With our in-house design capability, Cogplex provides a single, design-literate point of leadership across the full development lifecycle.
We’ve got decades of project management experience, spanning multiple industries.
We have the knowledge and expertise to handle anything. Trust us to deliver confidential, comprehensive turnkey solutions.
Marloes supports the delivery of Cogplex’s project management, design and development work, from feasibility through to completion. A graduate architect with a Master’s in Architecture, Urbanism and Building Sciences from Delft University of Technology, she brings a design-led eye to project coordination, with a particular interest in heritage, adaptive reuse, and the integration of architecture, interior and environment. Marloes works across both Cogplex and Sandcastle, helping connect Sandcastle's creative work to the developments it supports.

Additionally, Kieran leads Sandcastle Agency, delivering creative projects with strategic focus.

Meg leads communications and engagement across Cogplex and Sandcastle. A journalist and editor of more than two decades, Meg knows how to find the story in everything and get it down into words that work - for websites, campaigns, reports, presentations and community engagement. When she’s not writing for others, Meg writes flash fiction for fun and makes art out of wire. Usually there are dogs involved.

Not every project comes to us from the start.
Wherever yours is, we pick it up, test what's there and take it through to a working project.
Before you buy, build or expand, we assess the site or the business, check the title and the constraints, and set out your first options with a rough cost.
Can it work here?We set the brief, appoint the design team and run the design reviews, keeping the design on budget and true to its intent from concept through to detailed design.
What exactly are we building?We model the project before you commit: cost, revenue, finance, funding and the worst case. You see what has to go wrong for it to fail, and then decide whether to proceed.
Does it stack up?We set the approvals strategy, coordinate the consultant reports and work alongside your planner, while Sandcastle brings the community and council along from the start.
How do we bring the community along?We choose the right contract, run the tender and manage the contract award, so the builder is held to clear terms from day one.
We administer the contract through construction and handover, then help you get ready to open and trade.
In project management, marketing is often treated as something that comes later, a layer added once the hard decisions are already made. We think that's the wrong way around.
Sandcastle is our sister agency, specialising in digital marketing, public relations and community engagement. The relationship isn't just a referral arrangement - it's a deliberate integration of marketing intelligence into the way we approach project management.
When a project manager understands how a development needs to perform in the market - and how it needs to be communicated to the public, government stakeholders and community groups - the decisions made at feasibility, through design and across stakeholder engagement are sharper for it. Genuine community consultation and reputation-protecting public relations aren't afterthoughts; they shape the work from the start.
For Cogplex clients, that connection has real commercial value. Whether we're working on a tourism resort, a residential community, a hospitality venue or an agrifood precinct, the ability to stress-test a project against its market position, public reception and stakeholder relationships from the inside means better outcomes across revenue modelling, media perception and long-term performance.
Marketing isn't bolted on at the end. It informs the work from the start. Sandcastle brings the strategic marketing and engagement capability. Cogplex brings the project leadership and delivery discipline. Together, they give clients something that's genuinely difficult to find: a team where both sides already speak the same language, from the first community conversation to the last media call.
From inception to delivery and everything in between, we’ve got all your projects comprehensively covered.

We are not an architecture firm and we are not a builder. We are the client’s project lead - design-literate, commercially disciplined, and present from feasibility to handover.
