The Bridge, Deck and Pier F hav been closed due service reduction and passenger numbers dropping, so you only have the Wing F & J, Pier J or Qantas to use.

For napping I would prefer Qantas as they are quite empty during the day with long sofa padded benches to sleep, or Pier J as they have a napping area with day beds, not totally flat, but still quite a quiet place to nap undisturbed, as there's no time limit there, though get a blanket from the shower reception before going, or prepare your own. Earplugs or your headphones can block out the noise from final call / delay annoucements, just make sure you set an alarm so you don't oversleep.
