Perhaps QF management need to reassess their strategy of staffing A380 flights with a crew cost that is less than half of their historical crew cost. It's a great plan if properly executed -- but it hasn't been. The crew do their best with the resources that they are given; it is QF management that is limiting the available resources in various ways, and it has impacted the F service level. The collapse of F loads is perhaps unavoidable, but QF cutting service level while claiming to improve the service is probably not helping with the F loads.
All of the service issues on the A380 are easily solved -- yet it is now almost a year later, and getting worse rather than better. Maybe QF thinks there is no problem to solve ...
Meanwhile DL is running at 100% full in J on their LAX-SYD service (DL does not offer F). Sure it is just one flight, but finally there is credible competition on this route.
