So I responded "But you are checking in my bags, so what is the allowance as a BA employee will check them in, not a QF one". The response was "Please check with Qantas".....
It is quite simple, your entitlement is the BA ticketed allowance which is 1 x 23 Kg when checking in with BA; for the flight MEL-SIN the allowance should be 30Kg and for SIN back to UK, should be 1x23Kg
The BA Silver allowance is only an entitlement when travelling on BA/AA/IB only ( same as how Qantas's additional allowances for status only apply on Qantas only ) - there is no Sapphire extra luggage allowance benefit in OneWorld
Yours is an example though of how the non DOT rules are not as good since your allowance changes en-route and the excess baggage fees are very different
e.g. if you turn up with 46Kg at Edinbugh over 2 bags would expect to pay £65 at the airport for the extra bags.
If then checking in in Melbourne with the same baggage , then Qantas can apply its allowance of 30Kg and charge $30 a Kg = $480
(I do recall that in your case you are not bringing as much back, but most people do bring luggage back with them)
If the DOT rules applied, if the allowance is 1PC at the start of the journey, that must apply the whole way and if the extra piece charge is £65 , that must also be the charge the whole way
It seems to me, a lot fairer a rule to passengers than IATA's approach and avoids unexpected large charges
