please remember we are not experts. she really should be contacting authorities.
1. what is the best possible way for her to find a job once she passes the oet?
she really needs to check with the immigration dept, the hospital that she wants to work at, the nurses board in that state, and find a university that may help her convert
2. are the 3 month training courses necessary to get a job in australia for foreigners?
are you talking of those oncap programmes run through hospital? i think she would really have to check again with the above resources
3. what benefits are provided to nurses by the state or individual hospitals?
nothing really. free uniforms in govt hospitals. penalties in govt hospitals. in some hospitals, single person accommodation, though this is becoming really rare in the cities
4. what is the average rate of pay raises in australian hospitals?
difficult question as it differs from state to state. the private system and aged care usually pays less
5. what promotion opportunities are available, if any, if i work there for a long time?depends on the hospital, your qualifications, your skills
6. are their courses to improve my nursing rank as i work? such as from a lpn to rn?
we do not have lpns here. we do have enrolled nurses/registered nurses level 2. it is currently a diploma course. as suzanne 4 says, only rns are able to apply, unless your friend chooses to do the en course. to upgrade to an rn you have to do another 2 years i think...depends on the university. most courses are through university and are for specialties such as renal or cancer nursing. and they will not improve your seniority, just make you accredited for that area.
government nurses do have increments whereby every year where the respective nurse's pay goes up. but that does not give you seniority generally
