Why are they getting the longest range variant (the XLR) for domestic routes where the standard 321neo would suffice? 

This is a shame - so now Melbourne doesn't have a a direct flight to London, probably for the first time (correct me if I'm wrong)... And by direct I mean the same plane/flight number all the way to London (not non-stop as that doesn't exist, yet) - as Sydney has with QF1 via SIN. SYD gets 2 x B7...

The 'wellbeing zone' seems to be in the Door 3 location - but the images don't show the doors. Due to the lower pax count, could Door 3 be deleted, giving this space over to the wellbeing zone?
