We've repeatedly noticed the persistence of scam calls pretending to be technical support from Microsoft, Telstra and other large companies, and now there's a seasonally appropriate version in the wild: callers demanding payment for a parcel due for delivery from Australia Post. As ever, it's a con, and our advice is simple: just hang up.
As the government-backed SCAMwatch site notes:
Australia Post will never call you to request payment for an undeliverable mail item. If you receive a call that matches this description hang up!
Worth passing on to your more susceptible relatives and friends.
