The Fire Service says a "lapse of judgement" by two staff members caused it to lose $52,000 in a scam last month.
Fire Service chief executive and national commander Paul Baxter said and investigation by internal and external auditors found no breach of Fire Service IT systems and no collusion from employees.
The service announced it had lost the money in a Turkish-based scam last month.
"The investigation found our procurement and expenditure approval policies to be perfectly sound, but in this case they simply weren't followed," Mr Baxter said.
"As a result, we will be running refresher courses on relevant policies and also providing training on cyber risks."
