sz XL ? Australian Army shirt 8557

This is an Australian Army shirt. The label is worn but fabric and insignia in fabulous condition. Hardy shirt!

Buttons have hidden closure, pockets on chest. The name patch as been removed so there is some wear in that sectino.

I have washed this item but can’t see sizing on label so will share measurements. I think I see 2004 on label.
Measurements:

Made in Australia: 71cm long, shoulder to shoulder 49cm, armpit to armpit 59cm, sleeve 60cm
