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.

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.

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.

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.
