For each visa, the minimum score is 65 points. The higher your points, the more likely it is that you will be invited to apply for a visa.
Points are awarded on the basis of a number of factors including Age, English language skills, skilled employment experience and qualifications.
At the time you are invited to apply for the visa, you must show that you achieve the score specified in your Expression of Interest.
