The pilot award system does not count in Western Australia. So, effectively, in WA, you are "award-free". (this information is from ATO, Workplaceinfo...etc)
Not entirely correct. If you are a Heli pilot or an Ag pilot then you are covered by an Award. If you are a GA pilot you are Award free but still entitled to the minimum standards in the Australian Fair Pay and Conditions Standard.
You are also entitled to be paid for each hour you work. That means that every hour you are required to attend to the workplace (cleaning hangars, washing planes etc not just flying time) you must be paid for. This is the important bit because some people are of the opinion that if you are Award free you are completely on your own. Not true.
