Can i apply for work overseas even without a working visa yet?

Question

I plan to travel to australia and singapore and apply for jobs while i am there.

Answer 1

You will need the visa before you leave. If you go to without it you risk not having being deported as you will be entering the country as a tourist and trying to stay on fraudulent reasons. Australia will not allow you to enter on "good faith" and then see if you can get a work visa because there is a possibility that you may not even qualify for one and Singapore is even more strict.

You can apply for jobs online but in Australia if they like you they like to follow up with interviews in person. They don't hire that many people without meeting them first.

First link to Australian immigration and second and third to job websites.
