Federal police have arrested four members of an alleged cybercriminal syndicate which allegedly stole more than $1.7 million from Australian and overseas victims.

They say the syndicate ran at least 15 cybercrime operations between January, 2020 and March, 2023.

The investigation was sparked when an Indonesian business lost more than $100,000.

AFP Commander of Cybercrime Operations Chris Goldsmid said the incident in Indonesia was a case of business email compromise.

"Business email compromise is a type of cybercrime where criminals will take control of an email account of a company representative or a company employee. They'll then use that email account to send legitimate-looking emails that contain payment requests or invoices," he said.

"The account details will be altered to accounts controlled by criminals."

The AFP executed five warrants yesterday at locations in Queensland, Victoria and South Australia.

Two Brisbane women, a Melbourne man and an Adelaide man were arrested.

Fake passports, international driver licences, luxury handbags and digital devices were seized.

Commander Goldsmid said about $1.1 million was allegedly being laundered in bank accounts in South Africa.

"With the assistance of several financial institutions, we're working to close the fraudulent accounts that the criminal group is using to launder funds out of Australia," he said.

"The group was working with associates who sourced legitimate identity documents and altered the photographs and dates of birth so Australian syndicate members could use them.

"We allege that [the four] were involved in the laundering process.

The Brisbane women were arrested in Sherwood and Durack.

'Sophisticated offending'
