Optus delevieries tend to be very un transparent. If all goes well (in stock, shipped from warehouse, arrives in 1-2 days) its fine. You'll get a couple of SMSs at the start and end of the process. However if there's an issue then its a bit of a void trying to find out where your phone is. Generally Optus will send you an update when they post it and when it is marked as delivered.
