Yes if you're booking to SYD as part of a PE ticket you'll get works deluxe which gives you a meal and access to PE seating.
You'll have to post back afterwards and let us know what you think of the PE seats. I've still never flown in one, and it's safe to say virtually everybody regards them as better than the older 77E PE seats (which are just an economy seat with more leg room and more recline), people on here either love or hate them.
