I cant say anything definitive from these photos but I think it is highly likely the battledress is original, but whether the insignia is, or whether it was attached to the jacket during the war, is a different matter. High quality close up pictures are essential.
I don't doubt the battledress either but I do think it is a late war Australian item and I am not at all convinced by the insignia. However, "stranger things happen at sea" as the saying goes
Certainly clear close up images will help
It has the aspects of a reenactors getup. original easy to come by BD and replica insignia sewn up.
If its totally original you're sitting on a gold mine!
Better pics are need, but the BD is original though the insignia looks to be copies. Some close ups of the insignia are needed also the cap badge and the underside of the beret, also any labels or markings in the trousers.
Whatever its just an opinion.
i reckon only the battledress is original...
The patches throw me off from first looks. not feeling it at all
The Glider Pilot wings look like modern Repros to me as does the rest of the cloth.
Yes looks to be a 0riginal BD with repros badges added
