2019 changes to stopover rules extremely annoying

My brother’s family on a double round trip to try and replicate two stopover (SYD-HKG-SYD, HKG-NRT/HND-HKG, I’m currently with them in Japan). The lack of second stopover caused a last min repacking because the Japan sectors were Y (Australian sectors J) and they have to reduce the amount they brought over.
