I wonder whether anyone has a recent data point on interlining on QF from an award ticket?

I have an upcoming situation as I've added a NZ leg to an Australia trip on QR. I've got a QF reward WLG-MEL (booked via BA Avios) connecting to a MEL-DOH QR revenue ticket, separate PNRs.

From what I've read, there is an exception of reward-revenue and revenue-reward in terms of through baggage checking, but would appreciate any advice based on real life cases recently. I've got sufficient time in Melbourne to pick up my bags and recheck, but would definitely like to avoid the hassle if I can. All help gratefully appreciated.
