Business class amenity kits are only provided on international segments - and then not always on day-time short sectors like trans-Tasman. They will not have any onboard since the A332 is an aircraft type dedicated to domestic opertions.
On red-eye flights PER-SYD, WHY pax should be offered a basic kit similar to international flights.
Meal service should be pretty much up to international standards. There will be 3 main course choices compared to two choices on non-PER business class flights.
