Sentinel Due Diligence did not start as a business idea. It started because our founder spent a year working for a labour hire company that took money out of his pay every week and never sent it to the tax office — while quietly recording his employment as contract work.
In 2022, Sentinel's founder was working as a boilermaker through a labour hire company. It was ordinary work — long days on site, weekly pay, tax deducted from every pay packet like any other job. Nothing about it looked unusual from the inside.
The problems started small. Some weeks the hours did not add up. Days that had been worked were missing from the payslip. When he raised it, the explanation was vague and the shortfall was not fixed. Over the year, the pattern repeated — hours worked but not paid, and every week tax withheld from the pay that did arrive.
What he did not know at the time was that the tax being taken from his pay was never being sent to the ATO.
When the arrangement was finally examined, the picture became clearer. The company had been recording his employment — and the employment of others — as independent contractor work under an ABN. Employees were being treated as contractors on the books, while still having PAYG tax deducted from their wages as though they were employees. The deductions were collected. They were not remitted.
By the end of that year, he had lost more than $30,000 in unpaid wages, and the tax that had been taken from him every week had gone nowhere.
None of this was visible from the inside. Each element was ordinary on its own. Together they formed a structure that took money from workers and left them with no recourse.
Every payslip showed tax withheld, exactly as it would for any employee. The deduction was real. It came out of the pay packet before the money reached him.
The withheld amounts were collected but not passed on. From the worker's side this was invisible — the deduction appeared correct, and the shortfall only became apparent much later.
Work performed as an employee was documented as the work of an independent contractor under an ABN. This changed what the company owed, and removed the protections the worker should have had.
Some weeks, hours that had been worked simply did not appear on the payslip. When challenged, the explanation did not hold — and the missing pay was not restored.
The tax office had no record of the money taken from me. My employer did. That is the whole problem in one sentence.
Sentinel Due Diligence — founder
Nothing about the arrangement looked wrong from the outside. The company had an ABN. Workers had been asked to provide one. Payslips were issued. Tax appeared to be deducted. On paper, it was a functioning business paying its people.
What broke it open was cross-referencing records that were never meant to be looked at together. The classification of the work as contractor labour against an ABN. The PAYG deductions that showed on payslips but nowhere in the remittance record. The hours that existed in site logs but not in payroll. Each source looked clean alone. Together, they told a different story.
That is the lesson Sentinel was built on. Fraud and sham arrangements rarely hide inside a single document. They hide in the gaps between documents.
A registry search would have shown a valid company. A payslip would have shown tax withheld. Only by pulling the separate records into one place — and asking whether they agreed with each other — did the pattern emerge.
Everything about how this business works comes from that experience. The techniques, the reporting, the retention policy — all of it is a direct answer to what went wrong.
The arrangement that cost our founder $30,000 was invisible in any single source. It only appeared when the records were laid against each other. That is the method this firm is built on.
He was told things were fine. He was shown payslips that looked right. What he was never given was the underlying record. Every report we issue comes with the complete evidence pack so that nobody has to take our word for it.
He never got his money back, and the records that would have proven the case were held by the people who took it.
