To obtain Australian Permanent Residency (PR), you can apply through different visa programs such as skilled migration, family migration, business migration, and humanitarian programs.

The most common pathway to obtain PR in Australia is through skilled migration. The Skilled Independent visa (subclass 189) and Skilled Nominated visa (subclass 190) are the two most popular visas under this category. To apply for these visas, you must meet the following criteria:

1. Occupation: You must have an occupation that is in demand in Australia and listed on the relevant occupation list.
2. Skill assessment: You must have your skills assessed by the relevant assessing authority in Australia.
3. Age: You must be under 45 years of age at the time of application.
4. English proficiency: You must prove your English proficiency by providing your IELTS, TOEFL or PTE scores.
5. Points Test: You must score a minimum of 65 points on the points test based on your age, education, work experience, language proficiency, and other factors.

Once you meet the eligibility criteria, you can submit an Expression of Interest (EOI) on the SkillSelect online platform. If you are invited to apply, you can lodge a formal application for the visa.

It is essential to seek the advice of a registered migration agent to ensure that you meet all the eligibility criteria and provide the correct documentation. The visa process can be complex, and an experienced migration agent can help you navigate the process and increase your chances of a successful application.
