In order to give you any help, you'll need to provide more info about yourself. There are two categories of visas that fit most situations:
- family-related: are you in a relationship with an Australian citizen or permanent resident? Or do you have parents/children who are?
- occupation or work-related: if a family-related visa isn't an option, then an occupation or work-related visa may be. What occupation do you have education and/or experience in? Not all occupations are eligible and the ones that are require some combination of education/experience in order to qualify for a visa.
There are additional types of visas but these usually require a large financial investment or other less common items.
Speaking with a migration agent may be a good first start to see what your options may be.
