I actually don't understand the need for US style fully flat F seats on the Australian transcontinental. The US routes are very limited (depending on airline DCA/NYC/BOS/FLL/MIA - SFO/LAX ) with JetBlue soon to add SAN, SEA and LAS. There is some serious money there. By contrast the shorter ORD-LAX gets old style F seats, and it is slightly longer then MEL-PER.
A beg step up would be some sort of shell seat, that make it easier to get out from window and use a laptop - to avoid seats reclining into your face which is probably all that is needed for most flights ( the red eyes the exception).
