Every pinball sold should have a current test tag. Not one used pinball I've bought has been tagged. My NIB from AMD is the only pin I've bought which has been tagged, though no license number present.
No new device needs to be tagged, only once its 12 months old or second hand.
If the machine was to be sited then the receipt must be kept with the device to prove when it was brought and then it also needs to be tagged every 3 months in both NSW (recently changed from monthly) and Victoria. Not sure about other states though.
