Although it may be obvious to many I think it is also important to note attention to avoiding sunburn. Particularily for those of you coming from the Northern hemisphere, and especially so for those venturing to Australia. Our Sun burns especially hot and it does not take long before you will be suffering serious effects that may take the balance of your stay to recover from. Drinking lots Gatorade/powerade based drinks is a sensible option in any of the warm to Tropical regions, e.g Central Africa and so forth in order to maintain energy levels. Illness comes in many varied forms, be prepared and take the advice of your PH/outfitter who has your best interest at heart.
