If you are in a relationship with an Australian Citizen or Australian Permanent Resident or Eligible New Zealand Citizen then you can consider applying for a Partner Visa.
Partner Visa can be applied for onshore or offshore and you will either need to be married or be in a de facto relationship for 12 months. Couples must supply information to demonstrate the nature of their relationship to show that it is genuine and continuing. This includes financial, social, emotional, household evidence and commitment to each other.
Generally the partner visa is granted a 2 year temporary visa and at the end of the 2 year period, if the relationship is still ongoing a permanent visa is granted. For couples with children or for those who have been in a long term relationship over 3 years, you will be eligible for a permanent visa without waiting for the 2 year period.
