Foreign Posted Workers on Australian Sites: Certificate Checks

The A1 certificate is a European document and has no Australian form. The Australian counterpart is the certificate of coverage issued under a bilateral social security agreement, which lets an employer avoid paying superannuation (or its equivalent) in a second country for a worker sent there temporarily. Checking the documents of a foreign worker on an Australian construction site therefore means comparing four sources: the certificate of coverage from the sending country, the visa and identity documents, the employment contract, and payroll records. Each can be valid on its own and still fail the comparison: a certificate that ends before the project does, an employer name that differs from the contract, a worker on site who is not on the roster. This article describes what each check compares and what the reviewer does next. It does not claim that a check proves a document is authentic.

Rules are described as of 5 November 2026 and change; confirm them with the agencies linked. This is general information, not legal advice.

What does a certificate of coverage establish in Australia?

A certificate of coverage exempts the employer from paying super or its equivalent in the other country, while the home-country contributions continue. The Australian Taxation Office describes the outbound process: the employee must accept an Australian employer's offer to work temporarily overseas, the destination must have a bilateral agreement with Australia, and the employer applies before the employee leaves (ATO, certificate of coverage). Each agreement has its own start date and maximum period, which the ATO lists on its bilateral agreements page.

Those pages describe the outbound route. For a worker coming into Australia, the certificate is issued by the sending country's institution under the agreement in question; the reviewer reads the agreement's period on the ATO list, compares it with the certificate, and asks the issuing institution when something does not match. No Australian "posting declaration" equivalent to the European prior notification was verified for this article, so we make no claim about one.

What does each document prove, and what does it not?

Each document answers one question, and none replaces the others.

A VEVO check is a register lookup: it shows what the record says about a visa, not whether a certificate or a passport is genuine.

Which fields should be compared?

Seven comparisons catch most mismatches on an Australian site.

A spelling variant and an expired certificate do not carry the same weight. Log the gap, the answer and the access decision each time.

How long can a temporary assignment last?

The maximum period is set country by country in the agreement, so there is no single number. The ATO states that each country has its own agreement start date and maximum certificate period, set out on its countries-with-an-agreement list. The cross-check is cumulative time on Australian projects, successive sites included, against the period printed on the certificate and the period in the agreement.

What does a mismatch look like in practice?

A typical case is a certificate whose period ends mid-project. The certificate runs to the end of March, the programme runs to the end of June. Nothing suggests forgery; there is a gap. The reviewer records it, asks the employer to obtain an extension from the issuing institution, and checks the maximum period for that country on the ATO list before promising anything. Until the new certificate arrives, the subcontract should say from which date access stops, so the answer does not depend on who happens to be at the gate.

A second case is a headcount gap: the subcontract names twelve workers, the access log shows fourteen. The two extra people are held at the gate, the employer is asked for their certificates and contracts, and the date and answer are logged. It is an open item with a deadline, not an accusation.

What do site managers actually ask?

"Does the certificate let someone start work?" No. It addresses superannuation and social security coverage only. Visa conditions and site credentials are separate checks.

"The certificate arrives after the worker has started. Now what?" Log the delay, request the document and decide internally whether access continues in the meantime. Write the cut-off date into the subcontract.

"Is a clean VEVO result enough?" It answers the visa question only. The employer on the certificate and the period still need matching against the contract.

Where does automation help?

On a project with several subcontractors the table above becomes dozens of comparisons per company. A document-validation tool compares names, birth dates, employer and validity dates across the documents in one file and flags the gaps, with a log of what was checked and when. It shows where documents disagree; it does not say whether a document is genuine. Identity documents are personal information under the Privacy Act 1988 and the Australian Privacy Principles; the OAIC publishes the guidance on collection and storage.

Frequently Asked Questions

Is there an Australian version of the A1 certificate?

The closest equivalent is the certificate of coverage under a bilateral social security agreement. It plays a similar role for superannuation and social security, but each agreement has its own start date and maximum period.

Can a contractor reject a certificate it finds suspicious?

It cannot invalidate a foreign certificate itself. It can record the mismatch, ask the employer for an explanation or a corrected document, and take legal advice if the doubt remains.

Does a VEVO check replace the certificate?

No. VEVO covers visa status and conditions; the certificate covers which country's system applies. They answer different questions.

What should be compared first?

Name and date of birth on the certificate against the passport, then the employer against the contract, then the validity period against the project schedule.

Does an automated check prove a document is genuine?

No. It compares fields across documents and flags inconsistencies; authenticity rests with the institution that issued the document.
