avoid hotter and dryer weather. (try looking up weather for Oz I went twice both times out of hot season) but as you are there for a year keep to coastal ares during hotter seasons such as cains or Sydney.
Uluru (ayers rock) not best visited during summer months but do see sunset and sunrise there if you visit it.
Alice springs is overrated and best avoided unless you are passing through.
Blue mountains are nice and there are many other things to see not to faraway, such as Jenolan caves. best to have a read of lonely planet on OZ and when you decide where you are going/visiting research them before hand. Look at sites where visitors have been and left pictures and comments such as on holiday's or hotels. enjoy its a fab place.
