Swimming at the beach. I'll usually make a day trip to the Gold Coast about every 2-3 weeks in summer.
Fishing, although I rarely catch anything. I've got a tinny I like to take out, except it always breaks down. So I'm a pretty terrible fisherman, but I enjoy it.
Computer games, movies and tv. I love a great story with interesting characters.
Trivia. I love learning about everything. I often read random wikipedia articles. I go to a weekly pub trivia competition.
Things I hate:
Writing about myself
I generally try not to hate many things. It limits you as you never know when trying something you dislike will lead you to something you like.
