Is my itinerary eligible for Qantas oneWorld RTW redemption in business class?

Hi
I need a bit of help if this would qualify using qantas points.

SYD - SIN on BA already booked
SIN - HKG -PAR on CATHAY
PAR - GVA by land
GVA- LHR - HND - NRT - MLB -SYD on BA/JAL/JAL/QANTAS

it should be 34879 miles. I know it looks confusing but getting back to Sydney’s not easy

Also the already booked component cost 180K points the next leg should be 197K but should it revert to 318K when all booked.

thanks for any information

I checked syd-sin-hkg-par-gva-lhr-hnd-nrt-mel-syd on gcmap and the total distance is 23711 miles.

Did you ring up and add the remaining unbooked flights? This may be really obvious and unnecessary advice but you need to book under the same PNR/booking reference to get it under one RTW redemption.
