You didn't say what you need our opinions on. Be glad to help if you let us know. Are you saying that you can't use sunscreen with an SPF rating? Some moisturisers and liquid makeups have sunscreen in them, wear a hat and long sleeved cotton shirts and pants will cover the rest of you. I'm not in Qld but they are having lots of rain right now. If you get to Adelaide during your trip let me know.
