I'm applying for 4 - UTS and UNSW Co-op, Sydney Uni and Malcolm Chaikin. Might as well I say. Talk about work experience you've done, extracurricular activities, positions of leadership, community stuff etc show that you're motivated and take initiative. They have some real suckers in the UNSW Co-op questionnaire though like "What do you consider as your strengths and weaknesses" - you've just got to come up with impressive sounding human skills jargon I guess... somehow turn your weaknesses into strengths...
