haha!  i've been in adelaide since the 10th of feb 2011 bro.  for me it's alright. as long as you drink lots of water u should be alright. from what statistics show, it rains alot during winter and seldom during summer. it's dry during summer and wet in winter. for me the lip balm is not necessary but i do use moisturizer. and drink ALOT of water.   stay cool in the heat. it's not really that hot though. you can google adelaide's temperature now and see what temperature it is, the humidity levels and all. it's pretty cool now, down to 14.8 celsius.. this afternoon it reached 24 tops..   u planning to come to adelaide?
