I know you have figured this out [plotplot]. I did the exam over 30 years ago when ATPL was single exam. I have returned to aviation and asked to teach this subject. I would like to have a go.
1. BRW NZAA = 71 450KG + FBO NORM OPS = 85 400 KG < MBRW NZAA
2. LW YSSY with most FOB [Most Reserves Intact] at LDG = 85 400 KG - 14 900 KG [ FBO ONE INOP] = 70 500 KG < MLW YSSY
NOTE: I chose ONE INOP because you will land with the most reserves intact if in the best scenario you do not burn into it. You will have to carry 4000 KG WX HLDG fuel if you suffer and engine failure prior to the ONE INOP ETP/CP and need to return to NZAA.
3. ZFW at SHUT DOWN in YSSY = 70 500 KG - 100 KG [TAXI] - 1490 KG [VR] - 1500 KG [FR] - 4000 KG [HLDG] = 63 410 KG
4. Payload = 63 410 KG [ZFW] - 47 250 KG [BW] = 16 160 KG
