It's really hard to say. Feelings can vary through different law subjects as well - you might enjoy criminal law, but despise public law.
I would say in general though, that if you enjoy critical analysis, reasoning and problem solving, that you will at least be fairly interested. It's probably easier to define in the negative. If you DON'T enjoy them at all, or you hate reading articles, hate trying to extract ideas from the text (most textbooks are 50% extracts/judgments through which you self-analyse and discuss in class, as opposed to the textbook telling you what is what and all the answers - you can't simply rote learn, you can't simply practice, you need to really understand, evaluate and form your own opinion), enjoy being spoonfed, can't write essays to save your life (generally at least 50% of final exam is an essay) then... considering the course structure at UNSW, it's probably not for you.
