hi rocco- you’ll need to post some pics of the actual safe for it to be identified, and help give an idea of what’s involved and whether it’s worth doing. Try and get a good clear straight-on pic of the front, as the fit of the door in the body, the style/shape of the hinges and the positioning of the handle and keyhole etc are all critical clues as to what it might be.
Not a name or badge I recognize from the UK, but hopefully some of the others down under will know. There’s a strong chance it might be a re-badged safe made by one of the more mainstream manufacturers, in which case there’s even more chance of it being recognized 🙁y):
