The Australian economy took a dip like most Countries after the global financial crisis; However, Australia was not as badly affected as many other Countries and it's economy is recovering more rapidly than in other Countries due to heavy demand in the mining industry and related industries.
As a result, Australian businesses are scrambling to fill vacancies and are using the temporary 457 work visa to bring in skilled workers.
According to Department of Immigration and Citizenship (DIAC) figures, 42,840 applications were granted for the temporary 457 visa in the 11 months to the end of May, 38.3 percent higher than the same period in May 2010.
Twenty percent of these were for visas granted to workers in the mining and construction industries; There are large resource sector projects underway in both Queensland and Western Australia.
There were also many scientific and technical jobs available.
