I've never ever had an amenity kit on QF transcon (PER-MEL/SYD/BNE).
Unless you souvenir the contents of your plate (and of course, I do not recommend theft) there's nothing given no. I know some long haul overseas carriers give you little mementos but the days of that are slowly fading with the accountants trimming things away.
It's a nice way to travel, and QF J Domestic is widely regarded as one of the best domestic business products in the world (fly 'first' class in the USA and you'll see what I mean, with the exception of the 3-class SFO/LAX-JFK services that some carriers offer).
Of course if you can manage PER-SYD, you can get the 747 in a Skybed, but no amenity kits or the like still. That's strictly long haul domain.
