In Damien Parers book 200 pictures , it shows a couple of pics of the aussies using garands during an attack up in the pacific. whilst I realise it's a different are of ops, it does show thye used different weapons than issued. There is a drawing of a 2/6th commando in libya using a breda gun that was captured from the itlaians (wouldn'nt have had much use then) but the dtaes of the No4T like Max said could be out a little maybe. Who knows? anything is possible and probably is!!!

cheers
