If you have a skill that’s in demand in Australia, you can be sponsored by an approved business and work for up to four years in that occupation. Getting a 457 sponsored visa can be a challenge, but it’s currently the most commonly applied for and granted visa program for skilled overseas workers. You can bring your family with you (they can work and study) and you can travel in and out of Australia as often as you like.
