We literally just submitted an expression of interest for a lateral transfer. My husband is in the Infantry, and somehow wangled carpentry and joinery level 2&3 qualifications as part of his barrack manager job (thats still on the last thankfully).
I'd love to be kept up to date with your experiences as real life stories are not easy to find. Someone my husband knows (I don't really know his wife) will be making the move soon, he was selected for his skills and qualifications for infantry training as he's very keen and green and done every operational tour, exercises etc. He is a colour sergeant here but I think his new job is for a corporal. I hear the ADF like having operational experience so that might be something your husband could highlight. The ADF are quite specific I agree, we had a chat at the recruiting office in Parramatta when we visited my sister in Sydney in August. I had no idea that Infantry could only join the Infantry. I guess it makes sense but over here they can rebadge if necessary. Hey ho, lets wait and see what happens now.
I have an arrse account but don't use that email address any more, I guess I'll be setting up a new one.
