Australia has a huge number of visitors coming to our shores - both tourists and those who are looking to live and work temporarily and permanently. A huge part of this process is the use of 457 visas, which allow Australian businesses to sponsor overseas workers and bring their talents to an Australian enterprise.
In theory, it is a win-win situation for both parties. The business gets a wider talent pool, while the employee gets an opportunity that they may otherwise not have been able to achieve.
