Crazy what SecretFlying thinks is an error fare! They must do no research or they are so focused on Skyscanner to get their commission that they don't bother to look at Google Flights or elsewhere. Not only have I posted this in the past, but after I shared it travel-dealz did. Also, Google Flights pricing history shows that Air India has offered flights from MXP to Australia at this price before.
