Centralised Monitoring System (CMS)

The Centralised Monitoring System (CMS) monitors gaming machines and is used as a tool to calculate the Gaming Machine Tax and to ensure the machine is operating to standard.

All electronic gaming machines operating in NSW registered clubs and hotels must be connected to the CMS.

Maxgaming NSW Pty Ltd, a Tattersall's company, currently holds a statutory licence to run the CMS. Data Monitoring Services (DMS), a branch of Maxgaming, operates the CMS.

Venues must ensure that gaming machines are connecting and communicating with the CMS. If the CMS is not working, contact DMS immediately on its 24-hour help desk, 1800 706 221.
