Can we eat them then?

Let’s say they manage to create a population in Australia. With an ever so small surplus, we could take that and eat it. Prices for legal rhino burger would probably be insane, right? I mean - that and horns are why they are poached. And legal horns could be a thing then, too.

Seems like the best option for any animal’s long term survival is to become human food or amusement.
