I'll be booking flights from Perth to Glasgow in Y with one potential routing being PER-(QF)-MEL-(CX)-HKG-(BA)-LHR-(BA)-GLA without any stopovers. This would be a BA fare booked through BA.

What would my baggage allowance be for those flights as OWE? Am I correct that as the longest/major sector is HKG-LHR that I would be allowed 2 checked bags at 32kg as per BA guidelines? I'm wondering this as from my reading of QF's domestic baggage rules I would only be allowed 2 bags at 23kg and it's looking like my bags will be over 23kg.
