To assist retailers and consumers to ascertain if a phone has been reported as lost or stolen, Telstra are hosting an inquiry line which is 1900 964 634 ( call charges apply). This service will provide you information as to whether or not a handset has been reported as lost or stolen on the Telstra network.

Warning: This check only provides details of phones reported and blocked at the time of the inquiry therefore it is not conclusive. If the owner of the phone does not report it lost or stolen prior to your purchase, the resulting IMEI check cannot identify it as a lost or stolen.
