In 2017, Australian Taxation Office employee Richard Boyle raised internal concerns about debt-collection practices in the agency’s Adelaide office. He alleged staff were pressured to increase the use of garnishee notices, which allow the ATO to seize money from taxpayers’ bank accounts. An email shown on ABC’s Four Corners in April 2018 urged a team to use the “last hour of power” to issue five more garnishees. The episode portrayed an enforcement culture in which collection targets could take precedence over taxpayer circumstances.
Shortly before the broadcast, the Australian Federal Police raided Boyle’s home and seized personal items including his phone. He was initially charged with 66 offences, including using a listening device, recording a taxpayer’s tax file number and disclosing protected information; the Commonwealth reduced the case to 24 charges in July 2020. His prosecution became the first major test of Australia’s Public Interest Disclosure Act 2013. On 28 August 2025, Boyle pleaded guilty to four criminal charges in South Australia’s District Court and received a A$500 fine and a 12-month good-behaviour bond, with no conviction recorded. An Inspector-General of Taxation review led by Ali Noroozi found the conduct was not widespread but identified failures in training, communication and contingency planning; the ATO accepted all recommendations.
