Just stumbled across this deal in the Qantas Store. They are originally 57,750 points.
There's also 2 packs of the Apple QC25s for 79,160 points or 67,286 points with BDAY code (33, 643 points each). You can purchase any combination of colours i.e. 2 Black, 2 White or one of each.
Unsure if the system matches your account birthday as I haven't purchased from the store before..
