Work experience requirement
You must have a minimum three years work experience in your nominated (or closely related) occupation for all occupations within some ANZSCO unit groups these unit groups are identified with a tick under the 'Experience' column on our NSW skilled occupation lists page.
This applies to all SkillSelect EOIs regardless of when they were submitted or amended.
Note: your three years work experience must be deemed skilled employment. See our Common questions about skilled visas page for information about what employment you are eligible to claim for the purpose of NSW nomination.
