The Concealer

The Concealer hides their actions from being seen or known about to dishonestly gain personal benefits.


  • A service provider deletes records to hide their fraudulent activity.
  • An individual conceals the true nature of their circumstances to receive payments.

Case studies

A medical clinic owner defrauded the Commonwealth of more than $3.3 million by claiming rebates for services not given to over 5,870 different patients. He deleted the claims from the clinic's practice management software shortly after submitting them in order to avoid detection from employees and health practitioners of the clinic. The investigation was commenced when several members of the public made enquiries about their claim history for services they had neither sought nor received. The man pleaded guilty to 6 charges of fraud under the Criminal Code 1995 (Cth) and was sentenced to 6 years in prison.

Two men from NSW deliberately absorbed $450 million of otherwise assessable income through falsely created losses overseas to evade $135 million in corporate tax. The pair created a web of false identities to aid their deception and siphoned money through the UK, Hong Kong and the UAE via fake domestic and international companies to fund their lavish lifestyles. This approach resulted in $63 million in fraudulent gains. The scheme was described as incredibly complex and one of the largest tax fraud schemes detected in Australia.


Counter the Concealer using measures that support oversight and transparency:

Rotate staff and contractors in and out of roles to avoid familiarity. Staff and contractors can become too familiar with processes, customers or vendors, which can lead to insider threats.

Automatically match data with another internal or external source to obtain or verify relevant details or supporting evidence. This countermeasure is supported by the Office of the Australian Information Commissioner's Guidelines on data matching in Australian government administration.

Separate duties by spreading tasks and associated privileges for a business process among multiple staff. This is very important in areas such as payroll, finance, procurement, contract management and human resources. Strong separation of duties controls are enforced by systems. It is also known as segregation of duties.

Reconcile records to make sure that two sets of records (usually the balances of two accounts) match. Reconciling records and accounts can detect if something is different from what is standard, normal, or expected, which may indicate fraud.

Prepare summary reports on activities for clients, managers or responsible staff.

Conduct internal or external audits or reviews to evaluate the process, purpose and outcome of activities. Clients, public officials or contractors can take advantage of weaknesses in government programs and systems to commit fraud, act corruptly, and avoid exposure.

Audit logging is system-generated audit trails of staff, client or third party interactions that help with fraud investigations.
