I really liked the creative SAC for Literature last year. Instead of just talking and discussing about an author's style, you can actually show that you know what you're talking about when you try to replicate the author's style.
Of course, your teacher and VCAA understand that you are just 17 and 18 year olds and don't expect you to write to the perfection of the author that you're studying. However, they do expect to see the jist of that particular style and, in particular, originality.
Put aside your worries about replicating master works of literature, and you'll find it incredibly fun. You have free reign over ideas, story, narrative. Play around with words; experiment.
Of all the SACs, this was the one i enjoyed most and gave me the biggest insight into the mind of the author - because you actually begin to think like them as you outline your story.
