MSAW is active in Australian TMAs. But the CLAM alert (system monitoring of Cleared vs Actual Level) is always the first to be activated. Generally the MSAW goes off in error, or during the final approach phase (eg descending on the ILS) which makes it more or less useless. Various types of approach clearances or categories or flight or suppression areas also filter its effectiveness.
