SQ to QR luggage transfer?

[AuSammy]

Wondering if the brains trust can advise what the chances are of my luggage being checked through by SQ to final destination on an upcoming trip. (separate tickets)

Would their be similar experience on the return routing (QR->SQ)

Ticket #1. Y class SQ BNE-SIN-BKK

12 hr transit delay

Ticket #2. J class QR BKK-DOH-ZRH

[no status with either airline]

SQ-QR-SQ interline has been discussed here.
However, the interlining occurred at SIN which is SIN's hub.
