Don't know about the practical test, but guess it would be on the lines of the AM2 test over here.
One thing to know, dont do a ring main over there, it scares the jeepers out of them and they just dont understand a dual fed circuit. You'll get :89:if you do it.
Was there a several years back and if you got ya license it should be easy to get work. If you head west to Kalgoorlie area you can earn big dollars on the gold mine sites/refinarys. I was on $1200 a week + $75 a week put aside for redundancy when the job finished (doing 13 days on, 1 off....) And that was as a trade assistant/sparkies mate. All I done was pull in cables and ty-rapping them down in the glorious sunny bush land. There are good opportunitys if you wanna work hard. But that was 2003 ish
