Random call which when answered, held for a bit before hanging up. Came here to find out if it was another scammer

Unexpected call from this number. Didn't leave a message. Most likely the usual: scam artists using random Australian mobile numbers as their caller IDs. The number might not actually belong to the scammers but rather to some innocent unsuspecting people. It's just that modern communication technology allows scammers to put anything they like as their caller ID.
