As somebody who has worked in Oz and elsewhere, I'll pass on a few tips for prospective employees, without all the crap everybody else is going on with.
Firstly, register with ASA's recruitment section. Then identify the location and the manger of the unit you want to go to, and then apply for a job thru them. I had applied for 6 months with the recruitment section but heard nothing. Within 24 hours of touching base with the managers in Bris and Melb, I had 2 job offers. Be careful where you apply to go, because transfers between locations in ASA are almost unheard of. The managers guard their staff numbers like their first born.
Secondly, the money is adequate for an upper-middle class lifestyle. You wont get rich, and you wont starve. The government will tax you like you wouldn't believe, and still expect you to pay for things you thought were government provided. You can supplement your income by doing overtime, but that will be taxed at roughly 40%. All said and done, you should have enough money unless you have 2 wives and 8 kids. There is an outstanding retirement fund. Leave is generally good.
Thirdly, work conditions are good. The traffic levels are moderate and it is more about discerning who gets what service and implementing quirky rules. The only time it gets really busy is when there are thunderstorms. Apart from a couple of sectors, radar control is a qasi-procedural control with the radar used to supplement situational awareness. It is frowned upon to use your knowledge and judgement too much in the radar environment. Some may say that there is a heavy handed approach to performance management. There is a tendency to squash all the shifts into a short amount of time, which suits some and not others. The union is strong and the fees reflect this, but to be fair the fees do include loss of licence insurance.
The outdoor lifestyle here is second to none. Even in the cooler climates, there is plenty to do outdoors. However if you are from Britain and Europe you will not be able to experience the same pub or cafe culture and sense of community in Oz unless you move to a small country town or right in to the heart of the inner-city. Over 90% of the population lives in vast tracts of mundane suburbia, the type that inavariably ends up located close to airports and ATC centres.
Come to Oz if you crave the outdoor lifestyle, or have a partner who is from Oz and wants to return, or if you come from a country in which you no longer want your kids to grow up in.
Dont come to Oz if you are looking to enhance your career, cant put up with half-wit managers or just because you reckon it'll be just like Neighbours.
