The whole family immigrated to Melbourne

Cousins can't guarantee directly. First of all, there is no such thing as relative migration.

Only family members immigrate, and family members can only be their own family members. What do you mean? You can only support your parents and your children, not your grandparents. Only when you support your parents can your parents support their parents.

Cousin is more complicated. Suppose your mother's sister is an Australian citizen or PR, then she can only support her parents, that is, your mother's parents, then your mother's parents support your mother, and then your mother supports you.

Moreover, if there is an approval interval between family members and immigrants, the Immigration Bureau will not give you continuous approval.

Chefs have been removed from SOL, so neither ordinary skilled immigrants nor employers can guarantee immigrants.
