Last night's dinner on the ANZ SYD-WLG flight was either a Chicken pie (with a sauce sachet) or crumbed fish (no sauce!!!!) both served on a very bad rice "salad" . I agree that if you have Koru Club access fill up there, but at least leave room for the ice cream. The vegetarian option is nearly always a vegetarian spring roll on a couscous and pumpkin salad....very good.
A320 is better than the Qantas 737 offerings as the A320 have slightly wider but noticable seats, but if you are tall do not take a window seat, row 11 or 12 are exit rows so try them for that little bit of extra leg room.
Oh I actually prefer the Qantas Club food, especially in winter time for their yummy soups.
