Hi Ian303,
I stopped looking at government jobs as one of my friends works for them and she said that unless you are PR or citizen you wont get anywhere.
I know exactly how you feel which is why I have been doing temp work it doesn't help with super (pension) but at least you aren't sitting at home doing nothing which really annoys me.
Have you registered with seek.com.au and linkedin? they are pretty good both positions I have had have been from seek.
I wish you luck in your search.
