The Remaining Relative visa (subclass 115) allows people to move and stay permanently in Australia with their only remaining close family members who have settled in Australia as an Australian citizen, permanent resident or eligible New Zealand citizen.
The applicant should be the only person who is left in their home country and they don’t have any other family members left in their home country. The close relative meaning in this visa is your partner or your partner’s parent, brother, sister, stepbrother or stepsister, child or stepchild who has turned 18 years old and is not a dependent child.
Those near relative people can be your sponsor and they must agree to give you support, accommodation and financial assistance for the first two years of your residency in Australia. You will be eligible for this visa if you have met these requirements.
