The “easiest” subclass depends on your profile, but for many skilled workers, Subclass 190 (Skilled Nominated) can be more achievable than Subclass 189 because state nomination adds +5 points and some states have lower invitation score thresholds for in-demand occupations. Subclass 491 (Skilled Work Regional Provisional) is often easier to qualify for since regional nomination or sponsorship adds +15 points, making it ideal for applicants with lower initial scores. However, 491 is provisional for 5 years before PR via Subclass 191, while 189 and 190 grant immediate permanent residency. Choosing the right subclass depends on your occupation and points.
