CM3 Contractor Management and Prequalification

What is CM3?

CM3 is an Australian platform where a hiring client checks a contractor’s safety, licences and insurance before engaging them. The company trades as Cm3 (Cm3 Contractor Management Pty Ltd) and describes itself as a leading solutions provider for supply chain risk, safety and compliance management (Cm3).

Its own pages say a client sets its requirements, contractors create a risk profile and upload evidence, and Cm3’s assessors review it. Beyond prequalification, Cm3 lists a contractor marketplace, custom surveys, insurance verification, modern slavery and chain of responsibility tools, site access, online induction and permit to work (Cm3 for clients). Cm3 says its prequalification covers the risks a contractor may find on site and the risks it brings with its work (Cm3 blog).

Who owns Cm3?

Cm3 is a separate company from Avetta and ISNetworld. The Cm3 pages we checked do not mention Avetta or ISNetworld.

Ownership is changing. In its 2026 full-year results (27 August 2026), Wesfarmers states that on 24 July 2026 it agreed to sell Cm3, which it describes as a leading Australian contractor management software business that is part of the Blackwoods Group, to Achilles Group, subject to approval from the Foreign Investment Review Board (Wesfarmers). We have not found a source confirming that the sale has completed, so check the current position if it matters for your contract.

For a contractor, the practical point is that the invitation, login and rules come from Cm3 and your client, not from Avetta.

What contractors submit

Cm3 says the documents required depend on your operations and on your clients’ requirements. Its contractor FAQ gives these general examples (Cm3 FAQs):

Public liability insurance certificate of currency.
Professional indemnity insurance certificate of currency.
Licences and qualifications.
WHS policies, procedures, SWMS, JSAs and similar documents.

Cm3’s assessment guide adds that contractors complete a Business Risk Profile and provide evidence of the competencies, credentials, training and licences needed, that they understand the risks they may find or bring to site, and that their tools and equipment are fit for purpose (Cm3 assessment process).

How Cm3 prequalification works

This follows Cm3’s own “getting prequalified” and assessment pages (getting prequalified). Your buyer may add its own requirements, so treat it as a guide.

You receive an invitation. Cm3 says you typically get an email from your client with a link or a unique invitation code, and that you can also register without one.
You register and build a Business Risk Profile. You select the activities your business performs, so the risk profile reflects your type of work.
You submit the assessment with evidence. Cm3 says assessors first check that the risks in your profile match the risks in your evidence, such as SWMS, and that generic SWMS should be marked up to suit the work.
Assessors give feedback. If evidence is incomplete or incorrect, the assessment is returned and you work through the requested updates.
You receive Cm3 Certification once all requirements are met, and can begin working with your client.
You renew each year. Cm3 says previously submitted evidence carries over, but fresh evidence is needed for some questions (see below).

Cm3 also says clients and contractors are not required to adopt a predetermined management system (Cm3 blog).

What it costs

Cm3 does not publish dollar amounts on the pages we checked, so we do not give figures here. What Cm3’s contractor FAQ says about fees (Cm3 FAQs):

Pricing is calculated from your organisation’s Business Risk Profile.
It is an annual subscription, and Cm3 describes it as one fee for one year for unlimited clients.
Support through live chat, email and phone is included in the subscription.
Renewal is once a year and covers all your clients on Cm3. Earlier evidence carries over, but you must provide fresh evidence for some questions, such as worker communication, training and plant inspection.

The FAQ refers to contractors paying the fee. Cm3 does not say whether any client reimburses it, so ask Cm3 for a quote and ask your client whether it covers any of the cost.

Mining companies and Cm3

We found no Cm3 page that lists Australian mining customers or names mining as an industry it serves. The industries Cm3 lists include construction, energy, renewables and utilities, manufacturing, transport and logistics, and property.

The one resources name we found among its client logos is Heathgate Resources (Cm3 client logos), which describes itself as a unique mining company that has mined uranium in South Australia (Heathgate). Neither page says how Heathgate uses Cm3, and Heathgate’s page does not mention Cm3. Do not read this as a list of who requires Cm3. Ask the mine or resources company that invited you.

Cm3, Avetta and ISNetworld

All three are prequalification platforms: a hiring client sets requirements and the supplier uploads evidence for review. They are separate registrations run by separate companies, with different fee structures and different client lists. Our Avetta vs ISNetworld comparison covers those two and Rapid Global in the same format.

If you work for several clients, you may end up on more than one platform. Before you pay for a second one, ask the buyer whether it accepts a certification you already hold. Do not assume it will.

A platform is also not the same as a management system certificate. A prequalification check reviews your documents against one buyer’s requirements, while certificates such as ISO 45001 are independently audited. See ISO certification for mining suppliers. Cm3’s pages do not say whether a certificate replaces any part of the assessment.

What to have ready

Most delay is missing paperwork or generic documents. Our Supplier readiness checklist has the full list. For Cm3 in particular:

Current certificates of currency for public liability and professional indemnity.
Licences and qualifications for the work you will do.
SWMS and JSAs written for your actual work, because Cm3 says generic SWMS should be marked up. Start with our SWMS template and JSA template, and read SWMS and JSA for mining.
WHS policies and procedures that match what you really do.
A Business Risk Profile that covers every type of work you deliver for your clients, since Cm3 advises keeping it up to date.

Frequently asked questions

What is CM3 contractor management?

CM3, written Cm3 by the company, is an Australian contractor management software business. Its own site describes it as a solutions provider for supply chain risk, safety and compliance management. Its core product is contractor prequalification: a hiring client sets requirements, and contractors upload evidence such as licences, insurances and safety documents for Cm3's assessors to review.

Is CM3 the same as Avetta?

No. On the pages we checked, Cm3 is described as a separate company, and Wesfarmers describes it as part of the Blackwoods Group, not part of Avetta. Cm3's pages do not mention Avetta or ISNetworld. If a mining company asks you to join Avetta or ISNetworld, that is a separate registration. Ask the buyer whether an existing Cm3 certification is accepted before you pay for a second platform.

How much does Cm3 prequalification cost?

Cm3 does not publish dollar amounts on the pages we checked. Its contractor FAQ says pricing is calculated from your Business Risk Profile, that it is an annual subscription, and that one fee covers unlimited clients for the year. Ask Cm3 for a quote for your own business, and ask your client whether any part of the cost is reimbursed.

What documents do I need for Cm3?

Cm3 says it depends on your operations and your clients' requirements. Its FAQ lists public liability and professional indemnity certificates of currency, licences and qualifications, and WHS policies, procedures, SWMS and JSAs. Our free SWMS and JSA templates can help you build the safe work documents, though assessors expect them to be edited to match your real work.

Does Cm3 prequalification mean I can start work on a mine site?

No. Cm3 describes prequalification as a check done before a contractor is engaged. Site access normally also needs the mine's inductions, role-specific tickets and site requirements, which sit outside the prequalification platform.

Which mining companies use Cm3?

Cm3 does not publish a list of mining clients. Its client logos include Heathgate Resources, which describes itself as a mining company, but Cm3's pages do not say how Heathgate uses the platform and do not list mining as an industry it serves. Do not assume a miner's requirements from a logo: ask the buyer which platform applies.
