Okay - I'm commencing electrical engineering this year - and here is my understanding of it....
In Australia, most electrical engineering jobs are related to power supply and transmission - eg designing power stations, substations and working out stuff to do with the big power lines. You might also find work in designing the electrical layout for a big building or factory. Also there are a fair number of jobs in designing control systems - especially for the mining/resources industry. Some other fields you can enter include electronics and microelectronics - however there are not a huge number of these kinds of jobs in Australia.
As a standard electrical engineer, the average starting salary is about $45k i think - and with some experience an engineer can earn as much as $70k-$80k
However, most senior engineers move into management style positions which obviously have a lot more earning potential, and the salary can easily be $100k+
UNSW has a whole 5 storey building devoted to electrical engineering and the largest number of students, so obviously has a lot more resources at its disposal which you will appreciate when you come to do your thesis in 4th year. The curriculum is supposedly better than USyd and UTS, but thats a fairly subjective opinion.
UTS uses its 1 year of industry work experience which is built into the program as its major selling point - but people say its not particularly difficult to gain work experience anyway if you really want to - and UNSW requires you to have done at leat 60 days worth over the course of the degree - so you may as well graduate and start working sooner.
I noticed in your location that you are in the Eastern Suburbs - this means that UNSW would be the most convenient for you to commute to.
I'm sorry, I have absolutely no idea about the University of Newcastle, but looking at its program structure it looks very similar to UNSW in that in first year you basically do Maths, Physics, Computing and an introductory engineering subject then you begin electrical stuff in year 2.
Hope this helped and answered some of your questions.
