Correct, and in this case getting to work is YOUR responsibility and QF doesn't know or indeed care how you do it.
If you alt pax, or staff travel then QF ARE aware of how you get there. Ticking this box:
Flight Crew are responsible for ensuring that they are fit for duty.
When making Alternate Paxing arrangements, Flight Crew must consider how the
timing and method of their travel will affect their fatigue levels and must plan their
travel in a way that effectively manages fatigue.
seems to push responsibility to the pilot, but in allowing the alt pax I would imagine that QF share some responsibility.
