When you search AA.com on the date you need, does it show award seats SYD-MEL-DOH-ATH at the same price in miles that you paid when you booked your SYD-MEL-DOH-BCN ticket? If not, that could be the source of your difficulty in changing your flight plans.
That shouldn't matter. The only segment that needs to have award space available is the segment the OP is trying to insert into their reservation.
