Operation Protego

Sentencing details for Operation Protego, an ATO-led investigation into large-scale GST fraud.

Last updated 27 May 2025

About Operation Protego

Operation Protego is an ATO-led investigation into large-scale GST fraud that was promoted particularly on social media. The attempted fraud involves an individual:

  • inventing a fake business
  • lodging a fraudulent Australian business number (ABN) application, and
  • submitting fictitious business activity statements (BAS) to attempt to gain a false GST refund.

In May 2022 we issued warnings to the community to be on the lookout for fraud schemes being promoted through social media and other channels. We advised those who were involved to come forward.

The most serious offenders of financial crime are referred to the ATO-led Serious Financial Crime Taskforce (SFCT), including individuals involved in Operation Protego. The SFCT is taking firm action against individuals, facilitators and promoters suspected of defrauding the community by inventing fake businesses to claim false GST refunds.

You need to check the facts – nobody is giving money away for free or offering loans that don’t need to be paid back. Simply speaking, if you don’t operate a business, you don’t need an ABN, and you shouldn’t lodge a BAS. This is fraud.

For those who may be tempted by the promise of big gains, the ATO has sophisticated risk models. We work with banks, law enforcement agencies and other organisations to share information and detect fraud. We also have access to intelligence through community tip offs, and other information sources. The SFCT brings together the knowledge, resources and experience of relevant law enforcement and regulatory agencies to identify and address the most serious and complex forms of financial crime.

Gregory Pimm was sentenced to 2 years and 6 months jail for obtaining a financial advantage by deception, and 2 years for attempting to obtain a financial advantage by deception. These sentences are to be served concurrently. He is to be released on a recognisance order of $500 after serving 6 months imprisonment.

Mr Pimm reactivated an Australian business number (ABN) for a road freight transport operation. Between February and October 2022, he lodged 37 false business activity statements (BAS). He obtained $167,690 in GST refunds and attempted to obtain a further $302,825 in fraudulent GST refunds which was stopped by the ATO.

He falsely reported his total sales, the GST collected on the sales, GST on purchases made and GST credits the ATO owed him. The ATO noticed the inconsistencies in his reporting and initiated an investigation which found he wasn't running a business and wasn't entitled to any GST refunds.

Mr Pimm has been ordered to repay the amount of $167,690.

20 May 2025 – Skye Hoek sentenced to 3 months jail

Skye Anne Hoek was sentenced to 3 months jail after fraudulently obtaining $25,147 in GST refunds. She was charged with one count of obtaining a financial advantage by deception. Her friend, Ms Nutley, was sentenced earlier this month on similar charges.

Ms Hoek obtained an Australian business number (ABN), claiming to be running a retail business. She provided her myGov sign in details to another individual and gave them permission to lodge the business activity statements (BAS). Two false BAS were lodged in her name, allowing her to obtain the funds.

An ATO search warrant was executed at Ms Hoek’s residence, where investigators found no evidence she was running a legitimate retail business. An ATO audit and internet search later concluded she was not operating a business and not entitled to any GST refunds.

The ATO has begun reclaiming the funds Hoek obtained. Initially, the bank froze $23,666 as they suspected it was fraud. Those funds were recovered by the ATO through garnishee action. Further funds were recovered through her income tax returns. She has received reparation orders for the remaining debt of $780.

2 May 2025 – Tiarn Nutley sentenced to 9 months jail

Tiarn Nutley was sentenced to 9 months jail after being charged with one count of dishonestly obtaining a financial gain. She will be released immediately on a recognisance release order of $2,000 and is required to be of good behaviour for 12 months.

Ms Nutley obtained an Australian business number (ABN) for a business she claimed provided beauty and salon services.

An existing ABN was used to claim GST refunds. Ms Nutley provided her myGov sign in details to Skye Hoek and another friend. The 2 friends then arranged to lodge 6 false business activity statements in Ms Nutley’s name, allowing her to dishonestly obtain $49,700 in GST refunds. There was an attempt to claim a further $25,000, but this was stopped by the ATO.

Following a search warrant and an ATO audit, it was concluded Ms Nutley was not running a legitimate business and therefore not entitled to any GST refunds. During additional warrant activity, Ms Nutley said she paid $9,000 from each refund to Ms Hoek as payment for organising the lodgments.

Ms Nutley has been ordered to repay the amount of $49,700.

15 April 2025 – Joshua Merrett sentenced to 2 years 11 months jail

Joshua Merrett was sentenced to 2 years and 11 months jail. He is to be released after serving one year and 8 months, upon entering into a recognisance release order of $1,000, and to be of good behaviour for 2 years. He was charged with one count of obtaining a financial advantage by deception and one count of attempting to obtain a financial advantage.

He was also charged with one count of failing to comply with an order, as he did not provide his iPhone passcodes within 7 days to the Australian Federal Police after they seized his phone.

In June 2019, Mr Merrett registered for an Australian business number (ABN) for a business specialising in staircase manufacturing and repairs and antique furniture repairs. Between June 2021 and June 2022, he lodged 31 business activity statements (BAS). This resulted in $394,801 in refunds within a 3-month period, which triggered an audit and account lockdown. He attempted to obtain a further $336,193.

Mr Merrett tried to avoid ATO auditors but could not escape the consequences of his deceptive actions, as 2 months after the last GST refund was paid ATO investigators and Australian Federal Police conducted a search warrant at his residence.

The search found no evidence of any commercial activity, or sales or purchases consistent with running a business. However, they did discover evidence that identified another offender, who now finds themselves in court facing similar charges.

Mr Merrett will now have a criminal record and received reparation orders leaving him with a debt of $392,917. It may also impact his career prospects, ability to travel overseas and ability to obtain loans and insurances.
