Licensing or registration requirements
In many occupations you must be registered with or obtain a license from a local authority in the state or territory where you want to practise your occupation. Contact the local authority in your relevant state or territory to enquire about the licensing or registration requirements.
Professional associations
You may benefit from becoming a member of a relevant industry association for your occupation. This could help you with your employment prospects, networking, contact with industry and professional development and may provide you with important information and support.
