PROBLEMS with the Commonwealth Bank's internet banking website are due to a high level of traffic, some of which may be malicious, the bank says.

But customers' money is safe, it says.

"There have been no security breaches and no customer information, money or accounts have been accessed or compromised," Commonwealth Bank spokesman Steve Batten said.

"We are currently experiencing exceptionally high volumes of traffic, some of which appears to be malicious," he told AAP.

The source of the suspect traffic, and its type, had not yet been confirmed, he said.

Customers have frequently been unable to access the NetBank internet site on Monday and Tuesday, a problem the bank has been working to rectify.

"We are working as a matter of urgency," Mr Batten said, apologising for the inconvenience to customers.

"To maintain the integrity of our customer information and our systems it is necessary to prioritise workload and demand based on transaction importance and to balance that with caution," he said.

"Consequently, there have been planned intermittent periods where NetBank has been unavailable.

"The CBA (Commonwealth Bank of Australia) will continue to prioritise workload in this manner until we are able to identify beyond any doubt the source and type of this unusual traffic.

"Customer information and privacy must be secured at all times. If that is ever under threat we must forgo convenience for a short time whilst services are assured."

Customers with problems, questions or concerns relating to NetBank are asked to call the NetBank helpdesk on 13 2221.
