There are several cadetships on offer in Oz. Qantas has one, check their website and Ma-cair/ Jet-craft have one too. To do a search for that one remove the '-' from the search query. I can't recall their websites off the top of my head.
Realistically, at 35 you have a very slim chance at the likes of Qantas and Ansett. I am not too sure about Virgin Blue and Impulse (jets). Regionals are more likely to take you on however, you will need a far bit of time, eg +2000 hours, with +1000 twin and some turbine is the current 'minimums' at the moment. There are many other flying jobs that pay ok, eg Flying Doctor, Coastwatch and so on. Bare in mind that you will probably have to leave the city to get the hours up as well. Also, the pay scales is not very good initially.
So, check out the websites of the various companies mentioned, training costs aren't cheap. For pay rates, go to the Osiris site, it is the industrial relations site.
