No Coat of Arms
Kangaroo facing backwards
Well according to the government the coat of arms is a symbol of Commonwealth government "ownership and authority". Given that Qantas has been a private company since the 90's maybe it makes a bit of sense to remove the coat of arms? (even though they will remain on the tie pin apparently)

Also anyone notice how currently the emu and the kangaroo face the wrong way around compared to the official version? And anyone else have an issue with a flightless bird on pilot wings?
As for the kangaroo, it's facing in the same direction in the new uniform as the company logo (tail to the left, head to the right) as the official logo has it facing since at least 1968. And in the same direction as it was displayed on the 70's era uniform when it was in the centre of the wings:

As for the southern cross? The only symbol I could see where it was aligned horizontally was the Eureka flag, otherwise all other displays of it on national flags (not uniquely Australian as it's displayed on the NZ, PNG, Samoan and Brazilian national flags as well) has it displayed aligned vertically. Although to be honest it's hard to picture a southern cross from the way the five stars are aligned on the current badge.
