You will need a licence or registration if you intend to practice as a surveyor.
Licensed surveyors have specific expertise in the identification and measurement of property boundaries. They undertake surveys and planning applications for land subdivision and community titles. They are qualified to conduct surveys and authorise legal documentation. In South Australia, all property boundary surveys must be conducted or supervised by a practising licensed surveyor by law.
Registered surveyors have recognised expertise in areas other than land boundary definition. They specialise in engineering surveying, mining surveying and hydrographic surveying.
