Who we are

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.

Our people

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.

Where is your project now?

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.

Idea Testing

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?

Design

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?

Feasibility

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?

Approvals

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?

Procurement

We choose the right contract, run the tender and manage the contract award, so the builder is held to clear terms from day one.
‍

Who builds it, and on what terms?

Delivery

We administer the contract through construction and handover, then help you get ready to open and trade.
‍

Is it being built right, and will it trade?

Our sister company: Sandcastle

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.
