How to redeem premium economy reward seats from Canberra?

I’ve been searching for Premium economy velocity awards (international). I’ve found limited availability from Sydney but nothing from Canberra, as I assume the product isn’t available on the short haul and the system can’t handle it. I want to make sure both flights are on the same itinerary for the baggage allowance etc. Do I just call up?

Yes allyroger, don’t wait another 2 days without response, just call them.
