The process of transforming a tourist visa into a work visa is not permitted to take place during an individual's stay in Australia. The Tourist Visa (subclass 600) serves exclusively for visitors who participate in touristic activities or family visits and conduct business within Australia. The process to work in Australia requires you to obtain a suitable work visa either through overseas application or through the Temporary Skill Shortage Visa (subclass 482) or Bridging Visa application process from Australia. A registered migration agent must be consulted before you change your immigration status.
