Australia's copyright collection agency is investigating a suspected cyber attack that has disrupted services for its more than 37,000 members.

The Copyright Agency, which distributes royalties to authors, photographers and other creators for the reuse of their text and images, notified members of the incident on Friday.

“Copyright Agency has experienced a cyber incident that has led to an interruption of our normal services,” the not-for-profit wrote in a brief note to members.

“We are still at the earliest stages of investigating the incident and we are unable to provide any details of the investigation at this time.
