Do I need a city and guilds to work as a hairdresser in Australia?

Answer 1

If you're coming to Australia from overseas, you need to have your skills recognised here. That is a prerequisite for obtaining a work visa, but once recognised, you can work in any state except Western Australia without further registration.

See: http://www.immi.gov.au/asri/occupations/... for skills recognition information details

Answer 2

You need to be either  qualified or an apprentice.
