Not concerning Australia in particular but I think the Formula class is going to limit the sail size at 10m. Also having watched the PWA events, I wonder whether they are really going to limit the sail size at 9m. I know next year rules have already been validated but the big guys like Albeau were struggling in light wind for the course racing. The other option is that they keep the 9m max and they do only slalom course in light wind instead of windward/leeward. Being at 69Kg, I'm happy with the 9m anyway
