What kind of relationship do you need to immigrate to Australia? Can distant relatives?

The application for immigration by unmarried relatives is the most stringent. Applicants who have immediate family members and a stable source of income in the immigrant country may apply for family immigration. Generally speaking, spouses, unmarried children, parents, brothers and sisters can apply for relative immigration. As long as the applicant meets the conditions of relatives, has financial security, is in good health and has no criminal record, it is easier to get approval.
