Find Oil and Gas Subcontractors in Australia

Early access open

Oil and gas runs on internationally recognised certification rather than state licensing, which makes it unusual in the Australian market. The bodies that matter are OPITO, IWCF and API, and none of them is Australian.

This page covers what gets subcontracted in this sector, the credentials worth confirming, and how a job runs on Workforce Marketplace. Early access is open.

What gets subcontracted

The work most often subcontracted covers:

Offshore operations crews and specialist trades mobilised per campaign
Drilling support and well services
Pressure vessel, piping and storage tank inspection
Shutdown and turnaround maintenance on processing facilities
Pipeline construction, inspection and integrity work
Rope access trades for structures that cannot be scaffolded
Commissioning, and the documentation that goes with it

Credentials that matter here

Certification here is largely portable across borders, which cuts both ways: it is easy to verify against the issuing body, and easy to assume currency that has lapsed.

OPITO BOSIET for offshore survival, with HUET for helicopter underwater escape, and FOET as the refresher
IWCF Well Control Certificate for drilling and well services personnel
API 510 pressure vessel, API 570 piping and API 653 storage tank inspector certifications, verifiable through API or AINDT
NDT Level 2 in the relevant method, through AINDT or PCN: ultrasonic, magnetic particle, dye penetrant, radiographic or eddy current
IRATA Level 1, 2 or 3 for rope access, where the level determines what the person may supervise
H2S Awareness, Gas Test Atmospheres and Confined Space Entry across most facility work

OPITO and IRATA certifications expire on a short cycle and are checkable against the issuing body’s own register. Where a scope is priced on a certified crew, confirm currency at mobilisation rather than at award, because campaigns slip.

What to confirm before work starts

An active ABN. Where a supplier does not quote one, you are generally required to withhold 47 per cent of the payment and remit it to the ATO. Their GST registration also tells you whether the price should carry it.

That the credential is held by the entity you are contracting with. A person can hold a qualification while the business you are paying holds nothing. Check the name on the document against the name on the invoice.

Insurance appropriate to the scope. Public liability is the common one. Depending on the work you may also need professional indemnity, and workers compensation if they carry their own staff.

That the engagement is genuinely a contract for services. Since the Fair Work amendments the test looks at the real substance of the relationship rather than the label on the paperwork, and getting it wrong creates back-pay, superannuation and payroll tax exposure. Contractor vs employee in Australia sets out how it now works.

Writing a scope that gets comparable quotes

Oil and gas quotes are shaped by the campaign, not the task. Whether the window is firm, who carries the cost of a delayed mobilisation, how travel and accommodation are handled, what the standby rate is, whether the price includes the certification refresh cycle, who supplies specialist equipment, and what documentation and traceability the client expects at close-out.

How it works on Workforce Marketplace

Post the scope with the payment structure it actually uses, whether that is fixed price, hourly, daily, quoted or split into milestones for staged work. Subcontractors apply, and you compare them side by side rather than chasing callbacks.

Every account is ABN-verified at sign-up. Beyond that, subcontractors can submit licences, certifications and insurance for verification, which we review rather than grant automatically. Their profile shows the status against each credential without showing the document, the licence number or the ABN. Verification is opt-in, so a profile may hold credentials that have not been submitted, and it reflects the document as at the date it was reviewed rather than standing indefinitely.

Applying for work costs nothing and there are no leads to buy. Payment runs through Stripe, and Workforce Marketplace never stores your card or bank details.
