Hi there and welcome.

After scouring many websites for jobs for my hubby in Oz, there are loads of Electricians wanted over there and from what I can see the wages are on a par to this country. Obviously it all depends on experience and how good you are at your job. Take a look at some of the sites and you can judge for yourself, it gives you a good base line to work from. You will have to pass the TRA assessment and get a blue card out there to work.
If you can add to your installation course anywhere along the line it will benefit you in the long run.

The plus side is that you have plenty of time to save and gather all the info you need.

Good luck to you!
