On my recent review of award ticket rules you can make name changes.
14.7.4 Subject to this clause 14.7, the following changes are permitted to a Classic Award after ticketing and prior to commencement of any travel and will incur a Change Fee (see the Fee Schedule) per passenger:
(a) change to flight number;
(b) change to date of travel;
(c) change to class of travel;
(d) change to any Segment routing or airline;
(e) change to name (only for Flights with a Qantas (QF) flight number on the ticket that are operated by Qantas); and
(f) request to cancel ticket and re-credit Points. Please note that only Points that would not have expired will be re-credited.
