My name is Pablo I am from Argentina looking for job in Australia as electrician. I was working before in?

Working in Australia is not all that easy. You would need to apply for a working visa before going to Aus. If you don't have a working visa and turn up at the airport without enough money to support yourself for the length of your stay you may be refused entry and get put on the next plane home. Try surfing the internet for jobs in Aus and apply online an employer may be able to sponsor you and get a work visa for you.
