Important piece of advice — save some money. Australia is an expensive place. It can be quite daunting at first. You can’t help but notice the cost of groceries and rent relative to Irish prices. Ensure you have sufficient cash for a bond (deposit) on an apartment and to allow for a few weeks of not having any earnings.
Contract work is the way of life in Australia. Have your CV prepared and send it to recruitment agencies a few days before you arrive in your chosen city. You can search for the agencies online that are most appropriate to your industry. Don’t forget your cover letter, which should detail when you are available for interviews. Note that you must be interviewed by recruiters before they take you on their books. If you are anxious to start working as soon as possible, this will save you waiting for an email/phone call when you get there.
Consider a temporary position. This allows you to familiarize yourself with the market and earn Australian dollars in the meantime. Be prepared to start from the bottom. If you work hard, it will be recognized.
Relocating your life is not easy. Do everything possible to get as organised as possible before you leave. Be excited. Australia is a wonderful country to live in. The people, the lifestyle, the food, the weather, and the natural beauty of the land are things that are hard to give up
Good-luck :) !
