They have also advised that the community be vigilant with regard to retaining control of their personal information, and be aware of their surroundings when using ATMs.
Between February 14 and February 29, police believe a card skimming device was placed on an ATM at a venue on Corrimal Street, Wollongong.
Officers believe the card details of a number of ATM users were stolen from the ATM.
On February 29, officers from Wollongong Police District were notified of suspected fraudulent activity at the ATM and began an investigation.
Following inquiries, investigators have been told up to $9000 was stolen from a number of accounts during transactions at ATMs around Wollongong, between February 29 and March 1.
Wollongong Police District Commander, Superintendent Evan Quarmby said people needed to be "very cautious" about retaining control of their personal information, including cards and their PIN.
This included protecting their PIN when visiting ATMs, so they didn't become a victim of this type of fraud.
"Card fraud and ATM fraud are a persistent problem in a new world, and in a modern world where people use their cards often," he said.
"Police will continue to target this type of offence. We have a good description of the offenders, and we will continue with our inquiries to make some arrests in relation to these particular offences.
"Our message is very simple - if you see something that you think is suspicious, report it.
"As far as members of the community go, please protect your personal identity, protect your PIN numbers, and make sure you're aware of what and who is around you at ATMs."
