SIGNIFICANT INVESTOR
It is a 4-year temporary visa which can become permanent when later applying for the Business Innovation & Investment (Residence) Subclass 888 visa – presuming one has maintained an investment in Australia for 4-years or established an ownership interest in an Australian business.
You will need to spend at least 160 days in Australia on your Significant Investor visa, and be sponsored by a state or territory government to qualify for a permanent subclass 888 visa.
If you have applied for the Business Innovation stream, a 2-year extension is possible once you have held the subclass 188 visa for 3 years, giving you 6 years from the date of grant of the original visa.
