Fact: he was in the wrong, even stealing from you that he should not had done.
Fact: he deserves a good beating.
It is good you did not attack him like that, perhaps he was under the influence of some substance, or had some tool on him to hurt people with, he dared to go back, so he had some confidence, and you did not made enough impression on him (he betted he could fuck with you and get away with it)
I think it's unlikely he'll go back to you again, or return to the street at all. These just drift around.
Now as for the future:
What I suggest is to get on good terms with neighbours. Small gestures, small favors. If some ruckus happens with such bad home cunt, they'll believe you, and even back you up - maybe not in a fistfight, but with the police if it gets to that. But they might even help you physically, or call the police on the cunt, and help you with the self-defense claim. Who knows. Police won't care about couple of roses, but an assault is an assault.
Get fit. You don't have to be jacked, just trained, got used to exertions.
Get a stick, about a meter long or a bit more. If you don't see anything on him, he still might have a knife. Hit is hand holding the knife, there won't be a problem anymore with it. Even if it becomes a police thing, a knife is a tool suitable to take a life.
Have a prepared story that he was already aggressive and you got the stick to defend yourself.
I dunno about self- and property protection rights in Australia, here it was hard and criminalized, but now as far as I know, if someone enters your property you can do whatever.
