Explicit images apparently taken from the internet filled the screens of the internal information service used by reporters, political staffers and visitors before security guards managed to shut it off, the Australian reported.
The internal information service is used for updates on the nation's political events.
It was, however, not clear how the images appeared on the screens but Speaker Marzuki Alie said whoever was responsible would be punished.
"Whoever hacked the screens is insolent and will be reported to the authorities," he said.
