Well, why don't you just ask them?
That seems the obvious solution. Why not give them a ring? They worst that can happen is that they will say No. Here's their website.
http://www.awm.gov.au/aboutus/welcome.htmBrensec knows more about the AWM than anyone else here so you could also ask him. I think he still pops in from time to time. From what he's already said here the AWM is not an ordinary museum but is also treated as a memorial. Apparently photography of the exhibits is not permitted, unlike conventional military museums in most countries.
I feel that I should get a taste for this stuff, because if no one else does, whos going to know about it except in three years from now.
I don't think you need worry too much about that. If you're really interested in this you could become a Friend of the Memorial. I'm sure they always need younger people to carry on the work.
