In the RIW System, where a health assessment is completed and the health assessment requires a drug and alcohol test, if the drug test comes back as confirmed positive, the Authorised Health Professional (AHP) records the results and the RIW System automatically places a National block on the cardholder.

Whilst this is recorded on each Network Operator Australia wide, if any of the Network Operators has a rehabilitation mechanism or policy to support lifting the block on their Network, the Network Operator can lift the block for their Network only; meaning the block remains for all other Network Operators.
