A permanent partner visa can be granted earlier than 2 years after lodgement under which circumstances?

There is a dependent child (but not a step-child) of the applicant and sponsor, and their relationship has been ongoing more than 2 years.

The sponsor dies while the sponsor and applicant were in a relationship.

The visa applicant suffers family violence by the sponsor.

The couple has separated, and the temporary partner visa holder has custody of a child that the sponsor has been ordered to make child maintenance payments for.

The relationship between the sponsor and visa applicant has been ongoing for more than 3 years.

All of the above.
