HSC lingo tends to turn my brain into cotton wool (hence the lack of definitions I'm going to use) but I'd interpret that as "rather than regurgitating stuff from study guides, tell us what YOU think using examples from the texts to support your case".
For example if they want to talk about how important a form of a message is, points you might want to bring up are books (most people can read these days, books being easily avaliable in many languages wherever you go), also things like how the reputation/celebrity status of an author can help particular texts be read by more people (effectively spreading the message out to more people - for example Geri Halliwell's autobiography. You wouldn't touch it if she wasn't an ex-Spice Girl, would you?).
It's time like these when you need to have a firm grasp of the content covered by the course, and then be able to independantly think about the IDEAS brought up - not neccessarily quotes and "the use of <insert technique here> conveys a sense of blahblahblah", but actual ideas you come up with on your own.
To nutshell things a bit more (mainly for my benefit, I hopped off a plane this morning and my head is spinning - I'm not even making sense to myself at the moment :S), your paragraph topics should be ideas/concepts of your own (such as the examples above), and THEN you support this stuff with examples from the text.
Umm... *searches through computer archives* here's an example of a "paragraph topic" I used in my hsc year
"It could be said that the action of ‘digging’ might refer to a search for self-identity. " <blahblahblah about Heaney's poem "Digging" here>
