How can you get a entry level job for engineering in australia if u r a pakistani?

You will need a degree from a top engineering school, at least a bachelors, preferably masters. And Pakistani 'engineers' don't have much of a reputation. You would be in competition with Australians, Americans, Brits, Canadians, and more who have been to really good engineering schools plus excellent experience. No 'entry level' - you need good experience in addition to the degree(s). And Australia regularly updates their list of occupations acceptable for temporary employment visas or immigration. Lots of occupations have been removed from their lists over the past couple of years. They're pretty well filled up, especially as the world economy declines.
